[QUOTE="Filthy_McNasty, post: 1202632, member: 77501"] The most common problem that I can recall is damaged teeth on the sub-port drums from owners letting the service intervals for the top-end go too long. If you don't service the power valves regularly, they tend to carbon up and seize, damaging the drum teeth and the timing rod. If you ride the bike and it seems to have really soft power at low rpms, there's a good chance that the drum valves aren't functioning correctly. [/QUOTE]
