    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

You can probably blame that backfire on the same thing.... even if it was the petcock (which I doubt) you still need new float valves and seats. :)

as someone said above, they should be able to hold back the full tank by themselves in theory...

Thanks, and I suspect you're right. I pulled the carbs today and did a visual inspection of the floats and needles. There was some rust stain in the bowls, which isn't great but I assume came from the tank, but the needles and floats seemed to be clean and moving free. I didn't note anything stuck. I did not look at the seats, but the carbs were recently rebuilt so I'm hoping that's not the case. Changed the gassy oil and I'll install the new OEM petcock tomorrow and we'll see.
 
Just following up in case someone finds this later. New OEM petock installed today. And I removed the carbs and checked that no floats or needle valves were stuck. (Incidentally, removing and reinstalling the carbs was not nearly the pain in the rear it was during the rebuild. The new rubber boots have reshaped themselves around the carbs a bit, and maybe I knew what to expect a bit more.) I pulled the needles out and inspected the chambers but didn't remove the chambers or get into the seats. I didn't see any obstructions and everything seemed to move freely. I may have dislodged something small I suppose. But there is no mistake, the bike definitely runs better now. No more backfiring or sputtering, idle is smoother, acceleration is smoother. Starting is instantaneous. I didn't think it was bad before, but it's better now. I can't say for sure if it was the petcock or the floats / needles, but so far at least, no more leaks. The real test will be over the next couple of days after sitting on the kickstand.

Thanks for all the help.
 
good news! It's not unusual to go through stuff twice to catch a gremlin. They are tiny critters and can hide in small corners.
