On-board video (..and a question or two!)

[weeveetwin]

Hi chaps

Thought that the 'classic' enthusiasts among you might like to see some video I took yesterday, when trying out a new camera mount for the first time. It's not a Duc, but it's equally Italian .

I've tried in the past to capture the unique sound made by this bike, but I've never really succeeded. This is perhaps the closest I've come. Turn up your speakers!!

Now a question: She's developed something of a misfire, recently, which is (..I think) down to the poor seating of the float needle in one of the carbs. (..the float chamber is weeping now when the bike's leaning to the left on its side stand). At the first sign of the misfire, I checked the condition of the plugs, and found they were sooted-up around the electrode. Fitting 'hotter' plugs has helped a little (..they're nearer the correct colour now), but the misfire remains, and the bike won't take full throttle.

The carbs are DellOrto SS(I). I believe a version of this carb was used on the single-cylinder 350 & 450 Ducs. Anyone ever worked on these carbs? The float level seems to be non-adjustable: anyone know if this is the case?

Cheers
Steve

Being an amateur , i can't answer your question,
however, that's a good wee video,

I really like the colour scheme , it takes me back to my first T.T. in '79

as in, "It's not a Duc, but it's equally Italian", are Ducatis' not German now ?

This may be of use to you http://www.dellorto.co.uk/images/parts/ss1-diag.pdf eurocarb has spares for these carbs . Not had any experience with that version though! Iconic bike by the way!

Don't know about these carbs specifically but heard tales of the tips of the float needles being affected by the ethanol in the modern fuel.
I replaced one of my float needles as I had the same problem.
Away to listen to your clip now!

Hi Steve, enjoyed the video, would be nice to see a video of the RC30.

Thanks for the link Sam. The fitting of replacement parts will probably have to wait until summer (ahem!) is over. In the meantime I may just try to 'lap' the needle for a better seal (..with toothpaste, or similar. :lol2

239desmo: The float-chamber weeping has only recently started, but there could be something in the Ethanol theory. (The engine of this bike stays very hot for hours after it's parked, and the big worry is fuel weeping onto that hot surface!)

I am going to try this same remote camera-mount/microphone combination on the RC30, Andy. I'll add to this post if/when it works out.
