I've installed a SuperTrapp and it does help with 65+ performance. The information in the reviews on this page and the information on the graph from SuperTrapp show a slightly higher top speed and about a 10% HP increase, also cures a couple drop off spots in the stock dyno curve. As you drop sprocket size diameter, think about the belt stress turning that sharp bend, why not consider a slightly smaller rear sprocket, or see if the 5 speed gearbox will fit in a 4 speed and find one at a salvage yard. The 5th gear is only a slight change from 4th but does drop the engine speed enough to see 80+ without alot of vibration. Max
