I am just redoing my valve clearances for the first time on the bike. I had two inlets under spec, one inlet on the lowest limit, one exhaust below spec and one right on minimum. To be honest I was a bit peeved as the bike has only done about 1500kms and is meticulously maintained. I have calculated what size shims I need to put each valve back in the middle of the specs. I am hoping that I have got it pretty spot on with my calculations, as I don't want to have to buy even more hims if it isn't just right. Am I able to accurately perform a quick measurement of the clearances without having to re-install the cam chain and tensioner. Provided that the cams are in the correct position/alignment and bearing caps bolted down, I assume that the cams will be in the position of least resistance ie TDC Also, when re-installing the cam chain, provided the TDC marks are lined up, the cams "punch marks" line up horizontally, is there any other tricks to ensuring that everything is lined up properly? I am getting paranoid I could be out on the timing .
