loncin 125cc 4 stroke pit bike engine timing issue.

[Lewissenior]

hi i have recently bought a loncin 125cc (1p52fmi) engine in bits, there was no timing marks made on the cam or timing chain, there is however a small circle on the cam wheel, does anybody know what this is for? thanks.

This pic here shows it mate, did you find the flywheel timing mark?

there is 2 marks on my flywheel/magneto. one says T and the other says F, they are about an inch apart, when i line the T up with the notch on the crankcase i get TDC but there is no visible mark on the head to line the cam gear up with? any ideas mate?

The cam sprocket notch must be at 9 o'clock like the T is at 12o'clock, make sure the piston is at the top, the pic I linked is the way it will go

Scroll down the page on this link and it shows the marks from another thread.
