a little clutch slippage

[zipster68]

Hi,
I've got a little clutch slippage when I fully gas it in 4th and 5th.  Tiny bit of oil from the weep hole.  I'm facing a 1200 mile Lake Michigan loop this August.  Should I risk it?  No shudder during takeoff, clutch is freshly adjusted.  Only seems to slip when hot.
Also, from the photos.....do I have a RS or RT or fairing strapped to a stock K100?
cheers,
Ray

Sounds like a clutch o-ring leak.  The fairing looks like a cut down RT fairing on a C or s model.  I like it.

Put your moto's VIN in a VIN-decoder; all will be revealed. The fuel tank cap is 180º out of position. That can allow moisture to infiltrate the tank more easily.

Look for the rubber bushing indicated in the diagram where the front of the engine is mounted to the frame. If it is absent, your moto is likely a naked K100 that has been modified with an RS upper as TMG has indicated. There were no K100S or C models. If it is present, it's a cut-down RS fairing on an RS frame with additional naked K100 radiator shroud parts.

Contact by the clutch arm bolt should be just touching; I measure freeplay at the lever while using light pressure with just one finger on the lever. Sometimes a slight readjustment is all you need.

I'd risk it regardless. It's not mountainous. Just don't goose the engine. Fix it if you're risk-averse but it's a slippery slope—clutch disc replacement, o-ring, maybe a new compression ring, maybe new clutch pack nuts, maybe a new rear seal, how about the clutch rod boot, a new rod seal, maybe . . .

I've learned over the years that the Airhead/Oilhead/K dry clutch gives the hint of an issue always at WFO in the higher gears, where all the HP is on tap,  and almost never from a dead stop. Even with high power slippage, usually you still have some time. I go for that 2/3 day ride, just ride drag instead of  point . :beer:
