Important Fitment Note
: In order to decrease the engine running temperature, a cooling fan is now integrated with the clutch drum. The clutch drum is not backwards compatible without a small re-work of the crankcase (listed below):
The fin that has been used for guiding the belt needs to be removed.
Use a pair of pliers or a monkey wrench and break the fin along the dashed red line.
