How far does 1 tooth move the mark (sometimes if everything is lined up perfectly as you tension the chain the cams rotate) which can leave you a tooth out

Don´t know the 650 specs but on Z1/KZ900
15 tooth on crank and 30 tooth on cam sproket = gear ratio 2 to 1 = 48 degrees (2 tooth) on crank are 12 degrees (1 tooth) on cam sprocket.
As hardrockminer supposed, your TDC is 5 degrees advance on the crank = 2-3 degrees on cam = no problem.
Without a degree wheel and adjustable cam sprockets you can´t adjust the cam chain wear/stretch.

jekyllman Topic Author Offline User Posts: 58 Thank you received: 9	Thanks everyone. Just eyeballing it the difference equates to around 1/4 tooth on the cam sprocket, at most. I haven't fired it up yet. Hopefully this weekend. Just got the valve cover back on last night. 1980 KZ650F1 - 10k miles (see photo) 1981 KZ305 CSR - 10k miles (didn't have the heart to customize this one, will stay original)
