    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...

    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.

What is acceptable oil consumption --- 81' GS850G

I was using Shell T6 5w/40. Fuel economy seems to have improved a little, but I haven't finished off a tank yet.

I was using 5W/40 during the winter, which really helped cold clutch grab, but it was burning a little bit more than normal, although that didn't come as any great surprise. It certainly revved more freely, though; but the oil went off at around 1700 miles - the transmission got slightly notchy, like it always does when the oil is getting to the end of its life.

This summer I've been using 10W/50, with no downside so far.
 
Glad I found this thread. I just had to add some oil to my bike and I was worried it was maybe to much. Having said that .. I am losing a little bit of oil around the valve cover gasket in spots. Nothing major but after a few miles there is a light glaze of oil. I did the valves as instructed back when I started and installed a new gasket and now I am afraid of snugging it down any more on the aluminum heads. Sounded like using a torque wrench on those bolts was a bad idea from my reading and I dont trust my calibrated fingers. May give them another go when I take the tank off again.

after about 1500 miles I had to add 3 ounces of oil. Guess I should be happy!

Just changed to Mobile 15w/50 and the burn went from 1qt. every 300 miles to almost nil,wow...? Fingers crossed, lol.

Any change in fuel burn ?

Your '82 850L has a 4.5 gallon tank, you should go from FULL to REServe in about 150 miles. If you haven't "finished off a tank yet", I would say you have not gone much over that 150-mile mark.
Unless you have a cloud of blue smoke behind you that would make the mosquito abatement department proud, how are you going to say that consumption is almost nil?

Never mind, I looked at your statement again, you were using about half a quart in that amount to time, so it could, indeed, seem like "nil". :-\\\
