Twin Cam Valve Clearances

I?ve also found the clearances close up when you bolt the cylinder head on. I can?t remember the figures but it is enough to take them out of spec and it?s not equal on all cylinders.

Hi There
I've no idea if the changes would be repeatable or not but, now I think about it, it might be worth making an attempt at setting them on the bench to figures larger than they should be. They still of course should be checked once the head is in place but it might be they'll close up to the correct values and that will save a job. If thay don't, well you're really no worse off.
