Review: Installed the Bully EFI and have put about 700-800 miles on bike. Ran at std setting for about 300 miles before making any adjustments. Been making minor adjustments to find the combination I like the best. Bike set-up before Bully EFI........ Cobra slip on 2 into 1 exhaust with baffle. OEM air Filter. Air box drilled with six 1" holes. Performance before Bully EFI....... 47-50 MPG (depending on how I drive) Some pop and backfire on decel. (not horrible but more than I would like) Dead spot in throttle when coasting then trying to accel back to speed. This occurred mostly when going around corners or traveling very slow in parking lot. This was very annoying and to the point of being unsafe. AS you twisted the throttle nothing would happen, then all of a sudden a violent jerk. Tried installing a K&M air filter but everything got worse; Backfire, Mileage (40-42 MPG), and the throttle response. Bike set-up after Bully EFI......... Bully EFI. Cobra slip on 2 into 1 exhaust with baffle. K&N air Filter. Air box drilled with six 1" holes. Performance after Bully EFI....... 44-46 MPG (not happy about the decrease) Dead spot in throttle hasn't been eliminated but its hardly noticeable which is great. Worth the money for that alone. Bikes performance is noticeably better, better acceleration, motor runs smother at highway speed (70-75 MPH). Still has some pop / backfire on decel, maybe not as bad but still noticeable.
