slipping sound

[old stoner]

Just started for a ride and getting ready to shift to 5th, and started getting a loud slipping sound. This is a 1800 goldwing with champion solid axle. Went back home put it up on jack stands, started it and went through the gears and from 2nd up it made a loud slipping grinding type sound from rear end and driveline area! Any input would be great!!

Sounds like U-Joints.... Grinding..... Slipping ? Clutch, maybe ..... what oil You use? Has to be a Jaso MA Rated oil made for a wet clutch...

4T specificationsModern passenger car engine oils contain more and more friction modifiers. While this is the good thing for those segments (reduces wear and fuel consumption) it's bad for the motorcycles. At least for those motorcycles which use engine oil to lubricate their transmission and wet clutch. JASO introduced the MA and MB specification to distinguish between friction modified and non friction modified engine oils.

Most four-stroke motorcycles with wet clutches need a JASO MA oil.

Japanese standard for special oil which can be used in 4-stroke motorcycle engine with one oil system for engine, gearbox and wet clutch system.

Fluid is non-friction modified.

Oil isn't just oil anymore.... hope that helps.

Thanks for the response I received! Thought I would get more input but whatever! Anyway found the problem, my driveline was just about to come off the out put shaft!!!!! I got back on where it is supposed to be put locktight on the bolts and torqued to 12 lbs per manual. Everyone might want to check their driveline off and on!! Would of sucked to be going down hwy 101 and have the driveline come off!!!!!!
