Question

Answer
James......   Ignition timing????   Cam timing???  Gotta be more specific in your questions.

Flywheel markings have T (top dead center) and F (firing mark).

For cam timing set crankshaft position to T mark on flywheel. Rotate camshaft in head so the lobes are turned DOWNWARDS like an inverted V. Place camsprocket in the camchain and then install so that the 0 punch mark is straight up towards the top of the cylinder head. There may a mark punched on the cylinder head cavity to help with alignment.

You can go to: http://www.bikebandit.com/partsbandit/OEM-Parts-Nav.asp and find some illustrations of your bike's parts, but the camshaft sprocket/timing chain image doesn't show the punchmark, unfortunately. Just do as I have indicated above and the cam timing will be fine. Once the cam timing is set, you can also adjust the valve clearances at this position.
