What have you done on your bike today?

Injector washer puller is what the workforce use here to get them out of various places, we used them and blind bearing pullers when I was doing my engineering degree for similar reasons

^ that had occurred to me too. I'm fairly certain that it is still there. but I will take a phot of the V plug hole and compare notes. It is quite a fiddle trying to hod the torch and phone camera and line it all up.
You need a borescope. As well as the Skylift.

@Exige has a point though, just put a new plug in and accept there may be 2 crush washers on it. Maybe when you come to change the new plug in 30,000km time it will bring the old washer out too.

The problem with extra sealing washers is that it will affect the immersion depth of the plug - plus point is the extra washer will move the plug away from the piston so no interference with moving parts, but if further recessed in the head, and even with a two plug head, it may result in poor combustion, carbon build up around the electrode, etc, and could be even more of a bastard to get out next time.

IMHO, get the original seal ring out.

Something like this may work...

Very valid points 👍

I’ve a set of those picks and can tell you, before you spend money Hugo, they’re not long enough to reach down that plug tunnel in the head. However, they’re still very useful tools so add them to your shopping list along with the hydraulic bench, the wheel chock, the front and rear axle stands, the superbike stand, the Skylift and go get them. You’ll soon burn through the grant you don’t receive 😂

Edit: you can get extra long ones though 👍🏼


Get both sets

I wouldn't need any of this if your service facilities were a little more accessible.
 
The sun is shining in Dorset today.

I took the plug out of Bumpkin's H head (it came out easily with washer attached) I took a photo, it looked like the photo I took of mine. Then using the vernier gauge @Exige I measured to the depth of the hole to the seating and also to the start of the thread.
Back to my bike remove the mudguard, brakes and front wheel take measurements. There is 1.47mm difference, thus washer is stuck to seating.
Armed with some facts and more room to move, I (my son) could then screw the spark plug (welded to a rod ,2 turns through the errant washer and pull

Bingo out it came!

Thank you all for your help..

I haven't got a clue what all that means but if it gets you back on your Harley then I'm pleased for you :D

Give it all a real good blow out 👍
 
It's raining in Dorset today.
Having replaced the plugs with new ones gap set etc., new air filter, battery fully charged. We replaced the tank plumbed and wired it up pressed the button. The engine turned but wouldn't fire. Waited until the battery was back up to 14.5 whilst still on the charger, same again. Put jump leads not another battery to give it plenty of amps, still nothing until I opened the throttle then there was a bit of smoke as it tried to fire but wouldn't pick up.

Unless you (the gang) can come up with a better idea I shall drain the fuel and try with some fresh. It's hard to see why that should make a difference as it was working when I parked up last December 19th 2025.

Edit
Injector relay?
