    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.

Engine Cleaning?

What's a good way to clean all of the gunk off of a long-neglected 79 GS750 engine? Should I just use some engine degreaser and then spray the crap all off with a heavy stream of water? If so, should I have the engine running when spraying?

Thanks for the help!

I would start with the engine degreaser and a tooth brush. Then get your hands on a power washer and power wash it off. Then use a lot of simple green and do the same. Simple green not only acts as a degreaser, it smells nice and it is safe for the earth :) Ive been a long time user can ya tell? Then power wash. Honestly the power washing is what is going to get any built up oil and anything else off that and your fingers if your not carefull. Also depends on how dirty it is. Maybe take a couple of pics before your process so that you can see the before and after pics. Hope that helps.
 
Dont have the engine running because once you start spraying water, it creates a lot of steam meaning more cleaning. Do your cleaning and wipe with a lot of shop rags or cloths really well and then go from there.

I do that, with that purple Castrol degreaser and a nozzle, be careful not to blast the nozzle hard at a gasket, might cause a leak. Don't have the bike running at the time, seems like the water might crack something hot. Then take it for a long ride to get it thoroughly dry. Some people don't think using water is a good idea, as the water gets in places and doesn't come out, but a good ride seems good enough for me.
The degreaser may discolor the paint, be careful not to get any on painted parts.
Rifle cleaning brushes will reach way inside the cooling fins.
