Took out my wife's 2004 660 turbo trail for the day on sunday and notice a little clunking noise on the left side at real slow speeds. As i would excellerate it would go away. As i rode it, the noise got a little worse and i noticed a pretty good viberation at higher speeds. At the end of the day though it seemed to get better. Have had people tell me a bearing on the drive shaft, to a belt issue, and chain loose. Any thoughts. Seems like a pretty complicated sled and harder to find the problem than a normal 2 stroke sled.
