finding top dead centre

Recommended Posts

when i found top dead centre to check the valve clearances but when i lined the markings on the cams with the top like the manual says. the little mark u have to look at when u turn the crank is not quite in the middle. should i go by the cam marks or by this mark?

the crank has 2 marks on it TDC & a timing mark. If all you are doing is checking the clearances you will be close enough ether way you go

I was told to go by the crank marks. When the crank is in line and the cam marks are off, this is a sign of Timing Chain wear?? Any other thoughts????

I agree with Cycle Pop, the only thing I will add is you need to use the TDC mark I believe it's the second mark turning counter clockwise, set this mark first then check the cam marks I'll bet your real close. if those two marks aren't at the top of the case like the manual shows, then the chain stretched or you jumped a tooth the later I think you would have known. Just my 2 Cents :applause:

did you remove the rubber gasket from atop the head?

if not, you are not lining up the cam marks to the metal of the head (which is where you are to align them to).

This may be the cause of the error you see in the alignment.
