Engine in or out(valve shim)

Hi.just wondering is it awkward doing the valve shims with the engine in situ?
I've no problem whipping the motor out to do them

I found it easier engine out but I am not quite as deft of approach as some of the owners on here

We did mine in situ but it was a bit awkward in places what with the frame being in the way on #1 & #4 cyl.

It's a lot of work to remove the engine just for doing the shims. Better to at least measure the clearances & if they don't need doing then it'll be less faff.

But it was an easy job to do on not only my Exup but also my R1 if the radiator is unmounted & pulled forward. There's no need to pull the carbs but it does make it easier. On my Exup the biggest job was aligning the crank on the marker & then getting the cam timing right. This was more of a faff than any other procedure.

easiest way to do the cam timing is to use a bit of marker pen/nail polish and put a tiny mark on your chain and on your cams, as long as you dont then rotate your crank (which you should be able to do) you just re-align your marks and your good to go...

That's the way Mike and I did it banner. Makes the job a lot easier. We used tippex fluid.
