Well I just got my girlfriends vinson fired up, after a long long time. She blew the motor up, so instead of putting stock boring no performance parts in I decided to start the quest for more power[img]i/expressions/face-icon-small-happy.gif[/img]
I put the 581 big bore kit in, the web cam, fourstroke tech porting, hmf pipe, and some other little odds an ends.

It definately has quite a bit more power then it did stock, but I am a little diappointed, I thought it should have more.
I Ihave the jetting spot on, this thing runs great. Its still pretty slow, my stock prairie wipes the smile off this things face. Although I have to remember that this is my girlfriends quad, and it has more power then she needs.
It can actually do wheelies now.... with ease!
