Sport Pipe not as high quality.

The scooterworks pipe definitely is not a 100% bolt on and go. I kept the air injection assembly so, I needed new bolts and nuts. The air pipe was not in a good position and needed to stretch the hose a lot. Bent the air hose pipe a bit with an old shotgun barrel. Pipe has to be pulled down to the crankcase a bit, maybe a centimeter with the bolt. Wheel cover bracket needed some bending.

it does run way cooler though, with more power. also up jetted to 80 as recommended. Did the Malossi Varriator as well.
