I rode it today,it wouldn't run right without the air box lid but ran ok with it.I think it needs to be a size or two bigger because the bottom end wasn't as strong as it could be.I'm goin to the dealer wed. to buy a jet kit and get her dialed in.I have a 145 in it that came with the pipe,and I'm buying a dynojet kit.I would like to go to a 150-155 jet like the one that came with it.(not sure what brand the jet is???)What would you reccomend to start at with a dynojet?THANKS AGAIN!!!
