Last year we bought a 2002 R1150 RT for my girlfriend. It was barely used, with only 5800 miles on it. I did the 6k service, flushed the brake system, bled the clutch hydraulics, and all has been well. As of today it has 12,100 miles on it. Yesterday morning I took the RT on an Ironbutt ride. For about 600 miles of the 1100 + mile ride it was fine. After sitting for what seemed like an eternity waiting to re-enter the states at the Buffalo NY/Canadian border I barely noticed the engine seeming to rev just a little quicker than the bike was accelerating, only while under full throttle. A couple hundred miles later I got on it pretty hard in 3rd gear and the engine definitely took off without moving the bike appropriately. I nursed it through the remaining 500 miles of the ride, hoping to get home without having to call a wrecker. Just before I got home it was getting bad enough to slip at 1/2 throttle. I've read a few horror stories about early 1150 cc oilheads, such as premature input shaft spline wear, leaking input shaft seals, etc. My girlfriend has decided the bike is too heavy for her, so I'm going to buy her a different bike, sell my LT, and ride the wheels off of this paid for RT. I dislike broken bikes, even more so when they leave me stranded. Thinking about all of that this morning I decided I wanted to have a look at the input shaft splines anyway, so I decided to take a crash course in Oilhead transmission removal: Took a little bit to figure everything out, but it wasn't too bad. The input shaft seal of the transmission is completely dry. The splines look great as well: However, when I removed the slave cylinder I got a whole bunch of gear oil mixed with what looks to be rust running out of the back of the trans: The clutch disc looks good and doesn't really feel oily: The pressure plate has a little bit of oil on it, mostly out towards the edges: Other than that little bit of oil and a hot spot or two, things don't really look all that bad to me: This picure of the clutch spring leads me to believe my slippage was caused by gear lube travelling up the release shaft and then getting thrown out onto the clutch disc: My questions are: 1) Have I really found the problem? 2) Will an oilhead clutch slip with such a minute amount of oil on the clutch disc or pressure plate? 3) How is the gear lube getting into the slave cylinder hole, and how do I seal it so it doesn't happen again? There has to be more to sealing this thing than that silly little piece of felt on the clutch release shaft, isn't there? 4) Can I just clean up the slave cylinder with brake cleaner to get rid of all of the rusty crud or should I replace it? I really don't want to do this job again for a while. 5) Would you go ahead and replace the input shaft seal even though it isn't leaking and only has 12,000 miles on it? 6) Based on the pics would you believe the clutch is slipping or would you look elsewhere, such as the driveshaft rubber coupler? I've been through a broken driveshaft on a 2000 RT and the symptoms are largely the same. Incidentally the driveshaft on this bike looks ok. 7) Is there a particular way the driveshaft halves are supposed to be aligned before reassembly? 8) Will you come over and put this thing back together for me? Thanks!
