As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Clutch seems to be slipping after oil change

I changed the oil on my 80 GS1000 last week and used Rotella T triple protection. I used the 15w40 and the jug has the JASO MA designation on the rear. The clutch never slipped before the oil change but now it definitely feels like it its. Has anyone else experienced this? Suggestions?
 
That's the right oil, it didn't hurt anything. Adjust your clutch.
If it still slips, check the clutch springs.
 
yes, goto your clutch adjustment and loosen the lock nut, then turn in about 1/4 turn and then tighten the lock nut back up.. if that dont work you may need new fibers
 
I've had this happen with the rotella.

It was explained to me that while the oil itself is good for our old bikes, it does break down the old oily crap sitting around from regular moto oils. That broken down old oil can then become slippery.

Rotella had me see 16k+rpm on a 69 cb750 due to clutch slip (and stupidity by riding it hard even when I knew I was having slip problems). Can you say "bent valves"? I knew you could :)

Maybe you do need to just tighten em down. But as I said, I've had this issue with Rotella before. Again, nothing against Rotella. Just how it reacts to the crud already in your crank-case and oil system.

Other than replacing your bent valves, what did you do to rectify the problem with the oil?
 
Get new clutch springs. My old KZ had the same problem with fresh oil slip.

It's been sitting since that (it did get me the 60 miles home, though...) Sold it to a friend, he's in the process of rebuilding.
Everything will be flushed on that engine, I'm sure.
