well, its on, and for the most part id say im satisfied. Only issues i had, the new "air box" did not quite line up with the original air box tray. i had to drill one new hole, and widen the supplied rubber insertion bolts that came with the kit. They were supposed to fit snuggly into 5/8" holes, but it wasnt even close. i widened them by wrapping electrical tape around them, and forcing them into the holes. Sounds pretty half-assed, but it worked! Also, i modified a bracket that supports a rad hose, and shortened the supplied crank case vent hose. Other than that, the kit installed great. As for performance, there is definitely a NOTICABLE difference in pedal responsiveness. I really didnt take much of a test drive, or get on too much it yet, so i guess time will tell how worth it this install was..............
