BTW first time trying this.

As the cam pic sits take a pic of the FLYWHEEL timing.

Def at TDC on the flywheel, because I checked the piston before I put the head on and made sure the chain did not move the flywheel. The piston is on its compression stroke all the way up. 1drv.ms/1j6EF1b

Still need to see where the CASE POINTER IS POINTING to on the FLYWHEEL to be able to tell if your off one tooth.

Ok I see the case marker and of you rotate the CAM SPROCKET back to line up the two holes with the top of the head the Case Marker should be CLOSER to the LINE JUST BEFORE THE "T" if so your good to go.

Right now it is a little advanced but that is because the CAM HOLES are not both even with the head.

Alley you be the scooter GOD!!! Wow

[adamhoyer]

Final cam align, does this look ok? Its at tdc on compression. 1drv.ms/1k595Vb

[adamhoyer]

So both cams holes have to be evenly showing?

[adamhoyer]

using this as a reference for timing cam, but skip video to 5:18

[Alleyoop]

So now how the timing on the flywheel. I think your on because before you had to move the cam back which would move the flywheel counter clockwise and would then be right on.

No I lined up the piston before I tried to put the head on. The piston was all the way up on tdc at that mark. And it has stayed at that mark since.

[adamhoyer]

My flywheel is a little off or something.

Rotate the engine over by hand ti check for bin for binding .
