ADJUSTABLE CAM TIMING SPROCKET (HEAVY DUTY)
This adjustable cam timing sprocket for CRF110F is not only a real must have to get the best result possible out of your high performance camshaft, it's also "Heavy Duty" which means that this is a very very solid version of the stock cam timing sprocket you have installed from the factory.
Typically the little arm on the cam sprocket will bend, or if you really aren't lucky, it will break off and fall in your crankcases...
Even if you don't want to adjust your cam timing with this sprocket, the fact that this is a Heavy Duty edition is reason enough to consider installing it. Cheap insurance and also ultimate adjustability.
