I know it's probably a silly question to anyone who know these engines but I don't! I'm guessing the camshaft arrangement is shim under bucket rather than over - can anyone confirm? I need a 0.5mm set of shims to get the right valve clearances for my new cam...

Have you had a look at the manual?

I don't know but I'd assume the shim is under the bucket... I don't know of a bike with the shim above it.

yeah it is, remove the cam and lift off the bucket. best way is to get one of the telescopic magnetic pens, the shim will be stuck in the bucket, but some fall out so be careful you don't drop one into the engine.

how do you know what size shims you need if you haven't measured the shims in the engine? or have you just measured the gap?

What he said. I presume you have the rocker cover off at the moment and your getting your figure after measuring current clearances? Otherwise Id advise doing that first before you go ordering new shims.

sorry wasnt gonna tell any one about that, it helps me pull on a sat night

Well yes I'll measure it when it's all back together but the ballpark shim will be 0.5mm. The reason for this is that assuming it was shimmed correctly when I pulled the motor apart, the base circle grind on the camshaft will provide for 0.5mm less than standard so it'll need shimming up that much....at least that's the theory - I'll let yo uknow what happens in practice, but in the meantime, thanks for the confirmation...
