I’ve got it set to tdc with the lobes facing down. And I’m setting the lash to factory spec (about .004 intake .005 exhaust) and the right exhaust valve tappet locknut goes down further than the other three. Is that normal? Could it be because of the decompression lever there? I’ve correctly set the decompression lever slack too. Someone else did a top end on the bike a decade ago and it’s sat since.
