Well i pulled the hub off at TDC and decided to take some pics before i put the double roller on. Can anyone tell me how to tell if the motor is truly at TDC by looking at the timing chain?

you se that little notch or pin hold at the end of the cam pulley. there should be an equal 1 on the crank sprocket when both are facing each other #6 cylinder is at TDC. by facing i mean crank sprocket pin hole is at 12'o clock and that 1 on the cam is at 6'0clock,

Alright i found the one on the crank gear. It's not as noticable, but i lined the two up so now number 6 should be at TDC right?
