    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...

    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 posted a thread about the petcock on my bike and have read others... My bike will not run with the petcock in the "ON" position. I have to set it to "PRI" at all times. I tried riding the bike for about 20 minutes and while at a deserted intersection reached down and switched from "ON" to "PRI" and about 10 seconds later the engine quit and would not restart till I put it back to Prime.

So, this may explain while the bike is idling at 1800 - 2000 RPM when it is warm -- because it is running in Prime. Does this mean an overhaul of the petcock? Carb issues?
 
Sounds like either the vacuum is not hooked up or the petcock need some work.
 
Yep, pmilano is onto it: something's up with the vacuum operation of your fuel tap.
1. Check the vacuum line that runs from #2 inlet manifold, to the back of your fuel tap. It should have no cracks, leaks, etc.
2. If the vacuum line is OK then it's almost certainly the diaphragm in the back of your fuel tap needs replacing.

Replacement petcock parts

I took the bike to a shop and the mechanic said there are no parts for the petcock. He told me to leave it in PRIME and he installed a fuel shut off between the petcock and the carbs. Do you know where to find parts to rebuild the petcock?

Dont believe bike shops.They always tell you you their are no parts for these bikes. Try www.bikebandit.com or www.oldbikebarn.com or e-bay.Ther are plenty of other places if you keep searching. You will find one though.
 
Hi,
On old bikes like ours, it is a good idea to rebuild these things befoe they fail, in reference to the above post, I strongly suggest that you order a petcock rebuild kit from that eBay guy ( georgesfix), I "won" it on eBay a friday evening, he wrote to me saturday morning and shipped it 2 hours later ( I used my credit card).
