So I had to replace my head gasket and am going to have to retime and check the valve clearence on the bike. Got the Valve specs but the manual has no info about determining TDC on the crank. Can I pull off one of the covers and see a notch or line or something? The cam side seems easy with the pin counting and the lines etc. I just need a way other than watching the piston to be sure of TDC as there is a bit of leeway on that from the eye.
