Absolutely sweet freakin bike!
Belts started to be used by HD to eliminate chain noise.
revs have NOTHING to do with it! Those revs are completely irrelivant once the power goes thru the tranny!!!
My chop runs a belt!! And it puts down like 117hp and 117 torque. And besides, its the torque that will eat up belts not horsepower!
Leave them on. Those aren't that bad and they are hidden near the neck.
