well i bought my 06 last year used from a place called Ride Now. it had aftermarket exhaust on it(dual big guns). well i ran fine for most of the time. but then i had problems with it starting. so a friend helped me adjust the intake valves and it was good to go. then i took it up to utah(panguitch to be exact) and attempted to ride it. well it ran like crap(super fat), sucked gas and did not run at 100% and actually got to a point where the bike would stay running, but no power was being generated(at about 8500ft.) well i coasted it down the hill, probably about half a mile, ended up creating power again. so it made me think i had jetting problems at higher elevations. so got it back to vegas and took it out on a ride, still was running really bad. so i took it to a shop and had them rejet it. come to find out, the jets were not correct to match with the biggun, so he re did it. got it home and the motor seemed to be really good making passes up the street. along with him doing the work, he said that the drive belt is supposed to have 1.25" play or up to and said that mine had 3" of play. that would mean that the thing has to not even be attached, so how the hell does it spin the tires???? so he wants like 100 bux to buy the belt and then another 200 to put it in and im not really feelin that.
so i just want someone that knows about this beast to give me a heads up, maybe ride it, and tell me whats going on. and if that person can work on it, id be willing to pay, long as the problem/s are handled.
