I have a 2002 st1100 and have a problem with my clutch slipping. I have replaced the slave cylinder, rebuilt the master cylinder and no help. I dismantled the clutch and found two pressure plate and one spacer were bad. I am replacing the whole clutch and i am having problem installing the the clutch basket. I aligned the four dowel pins and also aligned the spline of the gear but no help. I wonder if anyone has an idea or if anyone run into this kind of problem. The motorcycle has only 30,000 miles and had no problem before. I found the hydraulic fluid was contaminated and thwt is how the problem started and when i took out the friction and the spacers plates they were all wet and i didn't know if this is normal.
