    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...

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.

gr650 oil streams from head

I have a gr650. Removed airbox a while back and haven been running pods. This morning the bike was running a little bit underpowered and I noticed that when I give it a lot of throttle and stream of oil is spraying out of my head through (if memory serves me correct) an intake port that ran from the middle of the head to the factory airbox. I expect it might be normal for a little bit of oil to leak from there but this is a full stream spraying as if it was coming out of a fountain. Any one know what could be causing this?
 
Your breather hose?
If so it's either a broken ring or a blown head gasket.
 
Chef, I'm not doubting by any means. But why do you say the head gasket?
 
Pressure from the compression/oil forcing itself under the valve cover will come out the crankcase ventilation.
 
Yes it is coming from the ventilation. It just seems like an awful lot to just be blow by. I guess I will pull the head tomorrow and take a look. If I can remember then I will get some video of it beforehand.
 
Curious, did you properly rejet your GR650 after the pods install???. If it ran too lean for too long you'll toast the rings, or worse burn a hole in the piston.
