    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. 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.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. 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 slippage

Now that I have my 83 GS750ES making some decent power, and I'm actually getting to ride it, i have found that (on occasion) if I get on the power hard, the clutch will let go a bit. The oil was changed recently to Bel-ray Synthetic 0W-40, and the bike has 63,000 kms (36,000 miles) on it. Should I be looking at a new clutch yet, or is the oil too thin, or ???
Thanks.

I would move up to 10-40 oil and see how it makes out. The thinner oil could be the problem.
 
Make sure the oil you are using doesn't have friction modifiers in it.

Thanks for the tip, and enjoy the trail! A beautiful ride, and a very distracting one...Wish I could join you!
 
Pull the steels and hit them with a bead blaster. Then re-install and shim a couple of the springs to increase the spring pressure. I had a honda I used to dragrace alot. Did this at least once a year. Tons of drag launches all on the original clutch this way.
 
I doubt the oil weight is an issue here. I race a GSX-R 750 (ex-factory race bike) that also used 0 weight oil (as done by the factory race mechanics... 0-20 or 0-30, it's been a while) and never had any clutch slipping problems.
