How do you set timing on Yamaha badger 80?

To set the time simply remove the black plug with a straight screwdriver located on top of the left side case, then remove the cam cover located on the left side of the jug. The cam gear has a line and the case has an upside down triangle. Line them up and take a flashlight to look into the hole where the black plug was. There is the markings f and t the t is time. Line that up with the notch in the threads of the hole. You will need to loosen the chain tensioner to rotate the gears, and that is located in the back of the left side case.
