1980 900SS rebuild...

Summer is on the way and Spring has well and truly sprung so I am trying to get my backside into gear and get my bike back on the road and do some riding.

This is the first of my two Dukes which came out of a twenty-three-or-so year slumber a couple of years ago. The good news was after a bit of coaxing the engine burst into life and ran really quite well; Although it looked a bit of a dog as it was running a dented orange tank and the cases needed a lot of elbow grease.

I got the bikes out of slumber as I had had to get rid of my Gixer K8 for financial reasons and was bikeless. I used most of the Gixer money to 'deal with things' and what was left got the old girl back on the road. I had some really epic (but slow) rides on it, the Gixer became a distant memory and I remembered exactly why I had like this bike so much.

In between times I lost both my parents and they were kind enough to leave me something; I think they had a pretty good idea what I might spend it on and both my Mum & Dad were great believers in thoroughness. That's my excuse for what is undoubtedly something I have always wanted to do properly but never had the means.

So I decided to take it off the road last April and really sort it out in time for the V Twin Rally. I didn't quite make the V Twin much to the amusement of my mates who drank my portion of beer and all I can say is I hope they all had hangovers (FX: Mutter, mutter).

When I finally got the whole thing back together a week after the V Twin, I was very disappointed with the stove enamelling on the frame; They had used red oxide primer, the paint was thick and so soft the cable ties were digging in. The black frame looked dark brown in strong sunlight. Also the guy who did the paintwork did a beautiful job in terms of quality of finish, however the tank stickers make the bike look like it is about to take off from Cape Canaveral; Needs fixing! Anyway, here it is running my spare wire wheels and missing it's fairing...
DSCF5223.jpg


Even worse, when I fired up the engine with the front head rebuilt by Pietro with new valves, guides and all bearings (including the self aligners), it was obvious there were deeper and darker problems with the engine.

So I ripped it down again, it felt like all the hard work and family money I had put into the bike had been squandered - and I'd failed to reach the rally. Here is the naughty engine awaiting tear down...
DSCF5357.jpg


I took the engine to Pietro for dismantling & inspection. The news was 'really quite bad'. Big ends on the way out, pistons had some scoring (although not too bad) and the oil pump looking a bit sad. The engine was still on it's original 86.0mm pistons.

The bill was going to be a stinker whatever I chose to do. Not wanting to repeat the rebuild for as long as possible I decided to address what I perceive as all of the main problems with the bevel engine, and do this without any external giveaways that this engine is one that might last. One that might last by design, not as a result of being the lucky engine assembled on Tuesday by the line's best engineer with a very fortunate set of accidentally blueprint perfect parts of perfect materials and running oil/filter changes every 500 miles by a diligent altruistic owner.

Anyway, that's the plan.

I am quite happy with the performance of the bike so no overt tuning mods going on, perhaps a quick gas flow and that's about it.

Already quite a lot parts have been procured and work done, The changes are:-
  • new 3 dog gearbox - the old one was worn but not overly so. However the combined separate parts costs to make it close to as new made it a no brainer to replace the entire cluster
  • straight cut primary drive gears - nothing wrong with the clutch basket or gears however the helical gears try and move the crank from side to side and it has been said the incessant forces can disintegrate crankshaft end float shims. So goodbye helical gears but I am retaining the (new) wet clutch for aesthetic reasons. Excitingly the straight cut gear set is a lot lighter than standard which will help the engine spin up more quickly
  • every bearing in the engine is being replaced except the plain bearings for the lower bevels and kickstart shaft, they were fine. Yes, that does include self aligners/lower bevels & supports. All bearings
  • high capacity oil pump & full flow lubrication system. Doing this means I can use modern oils which may well be the single largest gift of longevity I can give the engine
  • chassis wise, the only real change is I have had new rods made for my original Marzocchi ET85 shocks, so the Fontana's will be used elsewhere and this bike will have it's original shocks back on
  • the frame is being blasted and re-stoved (again) by someone else.

So this rebuild is really about the engine.

I have been really interested in what Martin has been doing with Eelco's Darmah and although a late arrival I have been watching it come together; Martin is approaching the oil filtration from a similar direction as I. I have almost had enough apart from a few pickies so I'll bung in the oil filtration stuff into my next post as I have just made some really nifty progress.

There is some good news in that the bevels all look good as do the cams & rockers. Both heads are getting new valves, guides, bearings & seals anyway. Here is the front head which has seen about an hour of use before being pulled off - at least it is completely done and re-shimmed so it can go straight back on.
7e734615-07b7-49a6-bcdd-2beb50f1ef40.jpg


Bottom end has been rebuilt by Godden Engineering and uses standard SS rods with new pin & Lacey needle rollers. It hasn't arrived yet and I can't wait.

Anyway, here is a nice new gearbox cluster from Andy@mdinaitalia
DSCF6791.jpg

And a nice new straight cut gear set from Nova Engineering
DSCF6475.jpg

And like many things, far more interesting from behind.

That's it for now.

Hi

As Kenny says keep it coming, there are many on here that enjoy these threads a little bit of inspiration below, not that you really seem to need that but nice to see all the same.

Its also good to see the committee getting behind the classic events such as the Moffat Giro and the likes which is just around the corner by the way, especially when the number of participents have grown so much since last year, well done you.

Sadly I will miss this years event :mad: but I would like to wish all a very safe and enjoyable weekend.

I might have the engine largely in one piece by then - but I am not carrying it to Scotland for Saturday May 14th! ;-)

Very nice bike, BTW.

Full Flow Oil Filtration on a Bevel Engine

If like me you've been around bevels a long time you will most likely have developed belt drive envy for their lubrication systems. The Pantah has a full flow filtration system with the filter where it ought to be - nice and low.

Their reliability was not lost on us otherwise happy bevel owners and many took matters into their own hands, coming up with many weird and wonderful interpretations including remote filters and all sorts of hackery and welding on crankcases; Mostly these were 'a very good thing' and bikes with one of these systems fitted properly like below are likely to be trustworthy machines. The most extreme seems to me to be by Kevin Bracken.

Here are a couple of examples...

IMAG0650.jpg

Here is the remote filter, under the tank...
IMAG0652.jpg

And how NCR did it...
NCREngineWithCartridgeOilFilter.jpg

I too trod this path and came up with a solution part devised by others and part home designed; I think the combination is one of the neater solutions and included nice machined from billet cam supports and a filter that screws in where you'd expect it to on a bevel. It kept one of my bikes running sweetly for many years. Here it is minus the pipework...
DSCF6272.jpg


However things change and my other Duke has standard unmolested crankcases and I'd like them to stay that way; So any changes can't be visible. A bit of research will result in the discovery that filtering the oil can indeed be done on early bevel engines without external modifications; The best news is the internal mods remain reversible should anybody wish to go back to a system which recirculates swarf.

So hat-tip to Roland Steidle & Martin Dauble (The 'a' in Dauble should have an umlaut too) who I hope won't mind if I use some of their drawings if I give them the full credit they deserve. Another hat tip to Damien Birch of Bevel Rubber fame, an unknown bevelhead called Pete at micapeak referenced in this post. There are others too. However a modified oil pump, a couple of 1/4"BSP brass fittings, some 8mm Bundy pipe, two steel spacers and a couple of 'O' rings according to Roland Steidle & Martin Dauble's specifications constitute the parts needed for a complete full flow filtration system for a bevel drive Ducati. Best of all, the external appearance is retained. See, no sealing wax required.

There is more good news. if you choose to re-use the existing oil pump, you will still achieve 15% extra oil going where it needs to because the original design bleeds off approximately 15% of pumped oil for parasitic filtration and return of cleaned oil to the sump. This can be further improved by restricting the flow to the heads to what they need rather than what they are fed as standard. The calculations and testing have already been done by others which means this is empirical data tested under harsh track conditions. What follows is my stab at translating the original German into English, The rough translations were done using Google Translate and Babylon 9 and then me trying to work out what they really wanted to say. So without further ado, over to Roland Steidle & Martin Dauble:-

Measuring the oil flow on an unmodified engine.
Measurements show that 16% of oil pumped flows through the oil filter. The vertical cylinder received about 22% and although using the same oil way dimensions the horizontal cylinder received approximately 27% due to being closer to the oil pump. The crankshaft received approximately 35% of the oil.

The oil way openings to the vertical & horizontal cylinders and crankshaft were measured at 5.2 mm. The oil way opening to the oil filter was kept original at 2 mm diameter. The oil pump speed was approximately 2500 RPM corresponding to about 5000 RPM of the crankshaft; The delivery volume measured about 9.3 L/min at 20oC oil temperature.

From above figures, it can be seen that 16% of the pumped oil is diverted through the passive filter and is lost for the lubrication & cooling of the engine.

Measuring the oil flow after the full flow modifications:
With the same arrangement as described above, the vertical cylinder receives approximately 35%, the horizontal cylinder about 34% and about 31% for the crankshaft. Since we are not losing 16% of the oil pumped back to the sump, 16% more oil is available for lubrication / cooling.

The difference in supply to the heads is the point where where the oil enters the oil circuit. In the original unmodified engine, the oil line to the vertical head was the longest. After the conversion is the oil supply is from between the cylinders from the oil filter housing and thus the oil way to the crankshaft is now the longest.

To restore the original ratio of the amounts of oil delivered to the crankshaft & heads, the feeds to the heads are reduced to 3.3 mm. The heads then receive about 30% each and the crankshaft approximately 40% of the oil supply. Since the heads are leaking too much oil in particular on the valve covers, we have further reduced the oil riser pipes between the cylinder and cylinder head to 1.5 mm internal diameter. This resulted in 25% to each head and 50% to the crankshaft (by calculation).

Oil Pumps
I had to buy a new pump anyway and the question for me was which one would best serve the needs of a full flow conversion. The next picture shows a standard pump and one of Andy's beautifully made pumps as backdrops, with three different oil pump gears in the foreground for comparison. From left to right, standard bevel gear, Monster 600 gear, uprated bevel gear from an Andy supplied pump.
DSCF6227.jpg

Another pump you can get from Andy is the Mario Sassi 'By Pass' pump. I was quite amused when I dismantled this one as the 'by pass' bit refers to Mario having built a brand new oil pressure relief valve into this pump, blanking off the old one. So now this pump - you guessed it - squirts oil out the side instead of into the main crankcase. So the spring, ball etc., went in the bin and I tapped it for 1/4" BSP, drilled the hole for the original oil pressure relief valve and I have a couple of holes to have welded up.
DSCF6424.jpg

Moving on (because it's late) the oil way under the oil filter does need to be faced off, recessed slightly and threaded with 1/4"BSP. Here it is done:-
DSCF6346.jpg

With that out of the way, it's time to make up the link tube between the oil pump and the oil way under the filter. This really isn't as easy as it might sound. 8mm Bundy steel tubing doesn't want to bend particularly, definitely not around a tight radius and certainly if at all possible with kinks. I believe I can do you a great service and show you what to buy and what to avoid. The correct tool should be about a tenner.
DSCF6772.jpg

The one you want is the blue one! The reason is the tight radius. I can tell you it is extremely hard to get the bends with the larger unit. I have done it but the pipe was a very tight fit hence quite difficult to put together. The blue tool is supposed to only go up to 6mm which means it is time to do some hackery...
DSCF6774.jpg

Bending the pipe was by far the hardest part of the whole process, I was beginning to wonder if the minimum order length of 3m of Bundy tubing would be enough. It has a slight compound nature to it's curves if you are using a high capacity pump in that the pump and access point are not in line with the filter entry. ideally you should be able to wiggle the pipe slightly and not so much feel movement as feel that it is 'not tight'. Then you can be sure when you are tightening up everything is properly seated. Here are a few of my failures...
DSCF6781.jpg

And here is success.
DSCF6771.jpg


DSCF6766.jpg

That's enough for tonight, I'm bushed.
Back again to finish off the post with a couple of relevant pictures I forgot because I was too knackered, the first being an outline of the tube...

Ooo, so shiney. I've got oil-pump gear envy. I think that the next bit is going to get even better. It has been an education and a pleasure to benefit from Vacant's patient research with which he is very generous. Inspirational! if I weren't going away again tonight I'd be back out in the garage again myself....

Part 2: Oil filter housing

We've got the oil to the filter now, although the eagle eyed will spot that the oil is flowing the opposite way through the filter than both was originally intended and convention. Hey Ho.

Old engines have a plug to control the amount of oil entering the filter housing. This needs to be removed which has already been done in this shot by me decades ago.
DSCF6269.jpg

New engines have a 2mm aperture as part of the casting like this
DSCF6159.jpg

which must be drilled out to enable increased flow. Don't worry, if you are convinced in future you'd like to reinstate the standard swarf re-circulation system, you can make up an ally plug with a 2mm hole as per the older 860 engines. It is reversible.

The oil seals which come attached to new filters are superfluous with the mod installed, as is the large washer part #075949875 which sits underneath the filter in a standard engine.

Note: The seals are both required in a standard bevel engine; The lower seal is sometimes compromised as people throw the baby out with the bathwater by accidentally throwing out the large washer underneath the filter when changing the filter. If you are running a standard bevel engine without the mod and that large washer is missing, no oil is being filtered.

The seals are replaced with tried and trusted 'O' rings protected by spacers (Yup, Andy has 'O' rings and metal spacers already made up). The spacers protect the 'O' rings by limiting how much they can be compressed when the filter housing is tightened down. The result is the filter is pinned from the top and the bottom ensuring all the oil goes through the filter.

This is how it is done:-
FullFlowFilterPartsDiagramsPage1.jpg

And assembled...
FullFlowFilterPartsDiagramsPage2.jpg

Revised oil flow is like this...
Ducati900SS1975OwnerManualRevisedOilSystem-1-150Percent.jpg

Here are the parts lined up...
DSCF6802.jpg

The far right hand ring is a ring magnet, we will come to that later.
In the meantime, let's start assembling. Here is the lower 'O' ring in the deeper of the two spacers too clear the lip on the bottom of the oil filter support shaft...
DSCF6805.jpg

Here is the next stage with the filter popped on and the slimmer of the two spacers encircling it's 'O' ring...
DSCF6807.jpg

And finally the underside of the filter with the ring magnet attached.
DSCF6808.jpg


Filter is pants

Might as well face up to it, this is a stingy small filter and it's going to be doing a lot more work; So changing the filter regularly is going to become a priority.

Aside from preventative maintenance, let's not rely on this excuse for a filter to do much except trap the boulders. Let's think about how to pick up and retain those sub 30 micron particles. Martin has glued some whopper neodymium N52 magnets into the filter cap - that will do the trick. I found this ring magnet at BevelHeaven, which will also trap the little sods. I gather Tony Brancato has something brewing too.
DSCF6414.jpg

What it does...
DSCF6415.jpg

I will be posting pictures of the build and hopefully won't be posting pictures of a subsequent failure (fingers crossed!). But that pretty much covers what I am up to with the engine; It's all about putting the engine together with an eye on reliability because as we all know in marketing, reliability breeds brand loyalty.

With the ready availability of the parts to carry out the mod, as long as the engine is already torn down it isn't hard to do. If you need a new oil pump anyway this mod isn't going to add much to the build cost - and might just keep the next build cost at bay for a long while.

Poor Andy.

Credits
I don't think this has been too hard as others have already done the research. So thank you to Ronald, Martin, Damien, Pete, MartinW and many others.

I'm sorry i don't have any pictures of the instillation now but i found this that shows the oil feed to the alternator/bevel gear etc at the bottom of the front frame tube. also shows the twin plug heads. What you really need is a bevel gazer just to be sure its all pumping like it should :)

http://i10.photobucket.com/albums/a103/F18/motorcycles/MyNCR.jpg

That's a great looking bike but I must admit the position of that oil feed or return is a mystery to me - especially since it looks like it comes off the alternator casing. It 's a shame you don't have more pickies; Do you still have the bike?

Godden comes good! And other miscellany...

Finally the crank turned up from Godden, brimming with Lacey Ducati bearings; Apart from new liners bored to match my new 86.0mm pistons, the crank is the final component I need before the engine can be built. (FX: Excited!)

So today's exciting metaphorical postbox included:-
  1. 1 x crankshaft ready to go
  2. 1 x 10mm aluminium threaded rod and 1 x 8mm aluminium threaded rod to use as:-
    • grub screws for blocking off entrances/exits for oil as needed
    • grub screws drilled as jets to restrict oil flow to the heads
  3. 2 x new liners

Yet Another External Full Flow Oil Filtration System - or YAEFOFS for short ;-)
I was a bit stingy in showing what my original 1980 ish vintage full flow oil system looked like. I can't show it attached to the correct crankcases as they are currently receiving attention at an engineering works - but I will. In the meantime, here are the main components...
DSCF6849.jpg

It was quite simple although spec'ing out the fittings took me an eon and both the fittings and pipework cost a fortune being contemporary F1 stuff. I had the billet cam bearing supports machined up by a small machine shop between Kingston Upon Thames and Surbiton.
DSCF6850.jpg

The neat oil filter mount/distribution unit is not of my making, I bought it from Newton equipment; The drawback is the oil filter housing has to be machined down to take it. Also the oil ways to the heads and between the two crankcase halves were sealed with grub screws as the oil was piped externally. It didn't leak and the engine didn't go wrong and was a very tidy installation. When I build the next bike I'll put the installation to the bike and take some pictures for posterity.
DSCF6853.jpg

Having read Roland & Martin's work, I expect purely by luck 50% of the oil went to the crank and 50% went to both heads, i.e., 25% each. I didn't jet the oil supplies to the heads so I guess it is just luck that it all worked so well. the nice thing is the fittings apart from the banjo washers (which can be re-annealed) are re-usable.

The New bottom end (TaDa!)
DSCF6828.jpg


Oil Pump - Finishing Off
The arrival of my aluminium threaded rods has enabled me to fabricate blanking plugs for holes in the oil pump which are no longer required. You can see an 8mm blanking plug blocking off Mario Sassi's oil pressure relief valve exit hole and also the 10mm blanking plug closing off the main oil pump exit to the main crankcase oil way. I am going to have these tagged with a spot of weld because I am either very insecure or have a love for making sure things stay where they are intended.

What you can't see is I have drilled a hole to accept the original standard oil presure relief valve ball.
DSCF6869.jpg

With the tagging done and the pipework complete so that it is easy enough to connect and swivel the pump into place, the internal part of the hidden full flow filtration system is complete. I have also meticulously cleaned the crankcases prior to dropping in the bearings.

I have yet to drop the new liners into the blasted and thoroughly cleaned blocks and send them off to a trustworthy boring service who know about air cooled motorcycle engines. I am considering using Dave Tag from SEP in Kegworth, Leicestershire simply because they sounded knowledgeable as a featured company in Classic Bike issue #385 February 2012 page 88. If anyone has any better ideas, please pipe up.

Oil Feed Restrictors/Jets
My next trick is to jet the oil ways to the heads in line with Roland & Martin's guidelines. I think they restricted flow by changing the metal oilway spigots between the block & head however I find these metal spigots b*gg*!s to remove so I am going to use a different and easier method which will allow me to quickly change the restrictors/jets if I so choose or have need. the following picture is an older cam bearing support for my other older bike.
DSCF6867.jpg


The oil feed to the cam bearing supports is suitable for being tapped with an 8mm thread, enabling me to make up short aluminium grub screws containing for instance a 1.5mm drilled hole. They can be removed if someone decides to go back to the standard recirculating swarf system.

'recirculating swarf system' priceless (well, about £2k really). I like your site for the restrictors better than mine, which is in the case/barrel joint and so much less accessible.

I need to get the liners/pistons bored/sorted so I just spoke with Service Exchange Parts (SEC) in Kegworth, Derbyshire. They sounded knowledgeable, helpful and reasonable so the work goes to them. £25 per bore + p&p and the usual government VAT drink from my already taxed wages.

Long time no update...

It's been a while and although I have been quiet I have been busy.

  • The FPS wheels are refurbed with new bearings & powder coating, look F.A.B and are ready to go on
  • Despite my disappointments, the engine is complete with it's fully fitted invisible full flow conversion and larger oil pump. Nice one Biggelaar, I'll come back to that in another post
  • I have gone solid state with the dashboard, courtesy of replacement LED dash indicator lights from Andy at Mdina
  • Frame is in for stoving next Monday
I am sick to death of removing the fairing and dismantling the dash just to change a really naff bulb; Some technology deservedly goes west. Anyway the only problem I came across was getting the indicator bulb working as believe it or not, if you check the wiring diagram you will discover that the left hand indicator lights the dash light by passing through the dash bulb and earthing through the RH bulb - and vice versa.

900SSWiringDiagramLargeWithLegend.jpg


I solved this with a pair of diodes, one for each indicator and accepted the volt drop.
SolidStateDiodeIndicatorMod.jpg


Anyway, wiring looks like this which I am not sure is any tidier than the original...

DSCF7448.jpg


And looks very nice when done (funnily enough, just like standard) but without the headaches. I now only have to worry about electromagnetic pulse when thinking about bulbs; Otherwise indestructible.

This was taken before I had resolved the dash indicator conundrum.

Earthing the indicator warning bulb through the indicator bulbs is normal practice still. I had to do a similar job with 2 diodes to allow me to fit an LED warning light on my previous ST4s.

Engine Rebuild with Biggelaar In Nederlande...

Where to start?

After a thoroughly disappointing culmination to my own work in terms of engineering capacity available to complete the build, things panned out. My good friend Jan-Willem suggested Biggelaar in the Netherlands, I expect the eagle eyed amongst you might have spotted that Jan-Willem might not be an entirely British name - in fact it might even be Dutch. And you'd be right.

So I called them and they were engaging, accessible and whilst not immediately available, were able to incorporate my build within a few weeks.

Again, Jan-Willem stepped up to the mark. This is all the more surprising as I have a competition running with his son who is completing a complex and complete rebuild of a 4 stroke 50cc Laverda scooter to be ready for his sixteenth b'day.

Jan-Willem had family business in the Netherlands and kindly took out the entire engine and dropped it off at Biggelaar. Thanks Jan-Willem.

That left me with the return journey to consider and also just how far I wanted to take the rebuild. Being an engineer, my soul shouts 'all the way' but I can't afford to have magnesium crankcases to be made up to my specification at the moment, oil filter where it is on the Pantah.

So, where to go? Really I want a standard SS which doesn't go 'bump' in the night (or day) so any mods which radically departed from standard were shelved; As opposed to my original plan, I backpeddled a bit and went for a combination of refurbishment and new. The engine is now as follows:-
  • New big end bearings by Lacey Ducati in standard SS con rods with new pin supplied and assembled by Godden Engineering, also new small end bearings and cleaned/replaced sludge traps
  • standard new 86.0mm pistons with new liners
  • Every roller bearing in the engine replaced, C3 where required
  • Mario Sassi high flow oil pump with invisible full flow oil conversion
  • Replaced mainshaft, new sleeve gear, 5th gear, polished selector forks
  • retained existing clutch basket & primary drive
  • new valves & guides
  • new unleaded friendly exhaust valve seats

Here she is boxed up to go...

And finally on my workbench. It is really quite heavy! Note the bodgers hammer bottom right. I really should have hidden it ;-)
DSCF7424.jpg


And one rather delicious picture of the end of my very expensive brand new sleeve gear, peeping out from where the final drive cover should be...
DSCF7425.jpg


What do I think of Biggelar? Straightforward to deal with, helpful, don't whinge and very knowledgeable. Did everything they could to accomodate me and my strange ideas.

£39 each way Dover Calais and a 3.5 hour drive each way to Oisterwijk.

Of course the proof is in the pudding so I'll only really know how well it has gone back together after running her for many years ;-) or as long as I can afford to keep her.

However, my vote of confidence is that I dropped off my 860GTS engine with Biggelaar when I picked up my SS motor; That's another story, thread & post and is part of the reason I have been quiet.

I expect to have the bike complete within the next four weeks and it is very likely I will use the old girl to get to the V Twin rally. I hope I will see some of you there in the sunny south. Bikes, band, beer and beautiful scenery; What more could you ask for?

Don't be put off by the fact it's organised by the Guzzi club, there will be a lot of Dukes & other V Twins present as well. The Guzzi Club do a very good job of organising this, it's a worthy meet.

Next up: Assembly!

Garage & bench...

You didn't see the garage a week earlier!! I had a massive throw out and quite a few dump runs.

I built the bench specially out of scrap wood I had lying around - it is designed to be bl***y heavy & sturdy, it's still missing its backboard which has a 4 socket 19" rack mount power distribution block I salvaged from a server rack, one of these Storage bin racks and space to hang some tools.

At last, somewhere not in my office I can keep clean and use for engineering widgety stuff.

Oil...

It's a good point; I will ask. I was a bit rushed when I picked the motor up, but with the oil filtration mod both you & I can take advantage of modern fully synthetic oils suitable for use with wet clutches.

These are the two oils I put forward to Biggelar and he was happy (for us) to use either:-

AMSOil also do a 10W40 which is suitable.

When I have a written response from Biggelaar, I'll post it.

They are both smellily expensive. FX: Ouch!
