    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.

I have burning oil on my left exhaust. The right three cylinders were about 70 to 80 psi for the compression check. My left cylinder was around 35 psi. After adding a touch of oil into the cylinder and checking the compression once again the pressure jumped up to 85. I'm seeking good advice on what is best to do at this time from people with experience. I assume I will have to pull the engine apart and change the piston rings which will then include the cam gasket, exhaust gaskets and cylinder gaskets.
 
I think you are quite right about taking the engine apart, but while it's apart, you might want to have a machine shop check the bores to see if they are still in spec. If the bores are out-of-round or tapered or just plain worn, you will have to bore them out to the next size, then order pistons and rings to match, so do that before you order new rings.

Yep, even the three "good" cylinders are below spec (100 minimum) so rebuild time.
 
Did you check them warm with the carbs at full throttle?
What kind of bike ya got?
 
Does the bike run Ok ? Those readings would make it hard to start As said! Make sure the throttle is wide open when checking. When was the last time the valves were adjusted ?
 
Are those pressure values in metric units of some sort? Most of us Yanks are only familar with psi when it comes to pressure.
