The only mods for power you have done thus far are a slip on pipe, filter, and new jets. I would say that if you want more power you need to go to a high comp pistion and new cam or a big bore kit. That or try to put a hyabusa engine in it. [img]i/expressions/face-icon-small-happy.gif[/img]

 

If you get the carb through a major supplier it's expensive, but there is a dealer on ebay selling them for $350. I had a friend buy one so I know it's not a scam.
