Put a new piston an rings in ny 2011 YZ450 and I'm at this point. I have the camshafts in and the timing chain on. Does the dots look like they are in the right spots? The Intake cam looks spot on. The Exhaust one looks bout right but dont know if it could be 1 tooth low. The lobes on cam (tapered ends) point toward each other as in the manual. However the exhaust lobes seem just a tad lower than the intake ones. If I was to go one tooth back on the exhaust cam to raise the lobes on the the EX cam, the cam dot on the EX cam would be way to low. The timing marks are aligned down at the cover.
