727cc big bore Yamaha Raptor dyno
This bike was built by Bo White. Dyno'd and tuned by me at Mobile Electronics in Tuscaloosa, Al.
First pull is bone stock on slicks with the filter lid on and the baffle taken out of the muffler.
Second pull is the same Raptor with a 105mm bigbore kit(102mm is stock), 12:1(stock is 9.2:1), my ported head with stock valves, Stage II Hot Cam, 2mm overbored throttle body, Cold air intake kit, dual exhaust, Power Commander fuel controller. Needs a little more tuning and a timing adjuster and itll be done.
