I'm having a problem with throttle control on the new bike. There seems to be no roll on with the bike. The throttle is either on or off. In ruts it's coming on to quickly and popping the front up and coming into corners the back locks up too abruptly. I've checked the throttle tube and it looks like its pretty much like all the other 450's, if not a slight bit smaller in circumference. Is there an easy way to get the bike to have more of a moderated acceleration. At the moment it feels like riding with a 1/4 throttle. I was wondering if it was a problem (or trait) that could be sorted out with a diferent map?
