Need some tech help from any Monster experts. Just bought a 1995 M900 with 20,0000 miles on it and was told that it needed to be rejetted. Being a bike newbie I accepted that, but a buddy of mine says the problem the bike has is unlikely to be the jets. The problem is that the bike has absolutely no top end in any gear. After about a half throttle turn the bike just doesn't rev any higher and actually backs off alittle. The fuel/oil filter and oil have all been replaced and the originally owner claims that the valves were recently adjusted 1000 miles ago. I'm going to take it in, but I was hoping to get some idea of the problem before hand. Thanks!
