    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...

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.

1978 gs1000e oil leak

My son resently bought a 78 gs1000e. Great bike, and in great condition, except for the basic 30+ year old issues. I've checked the search option and have read of similar issues, but just need some verification from you guys.

I own a gs750 and have worked extensively on it, but I'm far from an expert. My sons 1000 is leaking oil from the left side of the cam over. It leaks very little (nothing noticable) when driving around town, but when he takes it to the highway, oil actually gets on his left lower leg.

I think my issue is this. The guy who replaced the cam cover gasket last time used some kind of black gasket sealer, because I can see it kind of bubbled out sightly all the way around the cam cover. I have replaced the cam cover gasket on my 750 and didn't use sealer and I have not leaks.

Could the excess sealer cause the leak? My son said that the bike seemed to lose power when if got up to speed, the last time he had it on the expressway. Can this loss of power be attributed to the oil leak, or is that another "can of worms".

You seem to have forgotten the 10 common issues

The 1000 needs a valve adjustment. Order up a valve cover gasket and 4 half moons. Undo the PO s mistakes up there and properly install the gasket and half moons.

The oil leak should now be gone, along with all the goo

Oil leak is in no way related to power loss. Mine feels like they lose power at about 115 mph.

The crappy work visible should be a hint that there's more issues to come.

Thanks. I haven't forgotten, just wanted to start with the crappiest one. I'm balancing a son who wants to ride a lot, and working through the various problems. Nothing major, but you know... carbs, electricial, etc.

I appreciate your help, and it is nice to have your reassurance on the oil leaks. I won't even tell you how jacked up the electrical was. :^)

I agree with Big T, please perform some basic maintenance. Adjust the valves, and tend to the gasket and half moon seals as needed. There is no need for gasket goop if the gasket is in decent shape, but some sealer on the curved portion of the half moons is recommended. Do maintenance first, and fix any remaining problems second (if there are any).
