looks good......

 

Good? What are you talking about at 350 lbs that is great!

 

[img]i/expressions/face-icon-small-wink.gif[/img] I just don't want to get to excited..... I don't have mine yet and the Alaskan summer is ticking away.

 

And it makes max hp at ~8,200 rpm!!

 

So in other words it does stomp every stock machine.

 

Well..........I dont thi.....nevermind

 

I just got My bike back from Curtis sparks. He put a pipe on it, Jetted my carb & couple other little things. AND IT RIPS!!! iT HAULS ***!!! I MEAN I CAN'T BELIEVE IT. Curtis is lucky he isn't here right now because I would kiss him!

 

I agree with ridley, that doesn't look right. These motors make peak power at a higher rpm that 8000!!! Ridley knows this too i'm sure.[img]i/expressions/face-icon-small-smile.gif[/img]

 

Ridley would you care to guess about what hp 250rforlife is making with the curtis sparks pipe? I guess he would have took off the airbox, to wouldn't he?
