Clutch slippage

Post by coolrogue1 »



New Goldwing owner. 1985 GL1200i

I just purchased the bike and when I test rode it everything was great. (The temperature was in the 60's so I never got the bike up to "operating" temperature) Now after getting it home I rode it today for the first time "on the road", once the engine reached "operating" temperature the clutch started slipping. I watched the tach and the RPM would just start increasing while "going" down the road. I checked the clutch fluid level and it was good...Any ideas for what to check would be greatly appreciated.

These need oil with no friction modifiers. If PO put regular autopilot in, it will slip. Sounds like it could be worse, but that's a start. Most use Rotella 15-40 or Delo15-40. They also make motorcycle specific oils.

I am doing an oil change and a clutch fluid change and bleeding, I saw a similar post on the forum which gave me a few other things to check...

Another somewhat common occurrence is oil contaminated by gasoline. A leaky carb (float valve usually) can slowly leak gas when sitting. It eventually gets past the rings and dilutes the oil. If the oil level was too high, I'd suspect that. I bentca rod from hydrolocking from this last summer. If it's leaking, it needs attention.

Make sure that the return port in the clutch master cylinder is clear, as the engine fully warms any air/contaminates in the hydraulic line expands and slips the clutch. 8-)

Yes I saw that on another thread. It was clogged I cleaned it out and bled the line. I also am "rebuilding" the master cylinder
