1997 K1100LT. 96,500 miles+. Started to notice a growing oil leak under the bike when it was parked for the night. Suspected it was due to the rear main seal leaking. It turned out to be correct. Planned a couple of weekends ago to fix and do the "spline lube" while I was in there too. Ended up spending off and on the whole week and half to get the bike fixed and put back together. When I got to the old clutch plates, discovered the plates were covered in oil. (Believed the clutch to be original). Miked the plates and they were about 5. Regrouped, and a new plan of action put into place. Ended up following a "BMW 12K mile service check list" that I took off the internet. Put in new rear main bearing and seal, new clutch, working backwards all new seals, fluids, etc. New fuel filter, new front fork oil. New coolant/flushed. New brake fluid and bleed for front and back brakes. Checked valve clearances and clearances were in speck. Bearings in neck were worn and notchy so replaced those bearings. BMW dealer was nice (I think) and sugg that I utilize aftermarket bearings instead of BMW OEM bearings. The aftermarket bearings retailed for $30.00 dollars. I went for it. I will see how they hold up. Also, I saw that a vent hose coming off #1 on the fuel bar was blown off .... (explains a bit why I felt the bike was running somewhat rich). Tonight I'm on Max's BMW motorcycle parts list and the vent hose (part # 11151461834) is going for $76.00 :mbird New clamps will run about $9.00. Anybody have experience and sugg for alternative hoses/pricing? After the first 100 mile shake out ride, it appears that the bike is running great and no leaks ... (knock on wood). :riding:
