Yeah, the bike has been in the shop for rejetting twice. The first dealership put in 45 pilot jets and the bike ran like crap and would take 6 or 8 revolutions before it would sputter and start. The second dealer put 40 pilots back in and 120's for the mains. It runs great now, but I've been told that having some back pressure will add some power back to the bike. (it seems a little weak in the mid throttle range, according to them)
