performance question..

[motoxracer690]

I think I have installed all the "bolt-on" performance eq possible.

I have a K&N, eseries pipe, jets and modified airbox.. It still doesn't seem to hit the peak Rs...

I have also added disks, tweaked jetting and removed the airbox..

Is there anything else.. I try to compare to my buddies 450F... It isn't even close.

What about rev limiter? Will this really help?

Thanks in advance.

to compare to ur buddies 450f ur gonna need to do internal motor work... ur gonna need a full race 416,426, or 440...

u can add a carb to ur quad for about 450$ as a bolt on part but its not gonna show its full performance till u add a piston cam and porting...
