you are referring to a manual?
You didn't take any photos of the cam positions before you removed them?
Timing marks should be on the right side of the cam gears.
When piston #1 (left side of the bike) is at the top of the cylinder, you want the lobes on both cams pointing away from the spark plug hole. Basically you want the exhaust valve to open in about ninety-degrees of cam rotation, and then the intake valve ninety-degrees after that.
