Too Many Timing Marks
« on: February 09, 2018, 12:19:17 PM »


I've got custom camshafts and they're covered in various timing marks, arrows, chevrons, lines, letters...

What do the factory standard ones look like, which one specifically is the TDC timing mark, and where should they be at piston TDC?

Dear flayer of bearings, crusher of washers and devourer of Yamahas,

Since when did you get a 250?

P.S. I was going to add "stopper only for kittens", but I wasn't sure if it was true.

My 125 engine uses GV250 cam chains (wider than the 125 ones) and presumably GV250 camshaft sprockets. These are the ones with all the timing marks on. I doubt the 125 is much different but it seemed more appropriate to go up here.
