    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.

It's already been mentioned but if you want to ride a vintage bike you got to know how to turn wrenches! No experience? Find a lawnmower, weed whacker, chainsaw etc. and start there. Get that puppy running perfect and keep it running perfect for awhile. After you've gained some confidence move up to something with a twin cylinder such as a smaller bike, outboard motor, etc. Same deal, make it run perfect and keep it running perfect. By then you should have accumulated enough tools and knowledge to take on a four cylinder bike, just make sure it's not your only transportation. There's nothing worse for learning than being flustered and in a hurry.
 
this is crazy!!!! if the air/screw doesnt make a difference that osunds like the problem. pull it out and check the o-ring in there BE VERY CAREFUL NOT TO RUIN ANY THREADS! i would take it out clean it and replace o ring
 
I agree! i got my bike in december. i live in ohio so i couldnt ride! i bought a clymer and read this website pretty much every day as i went through the bike. the clyhmer even has sched. maintenance procedures .
 
(...)A 37 yr old motorcycle is not going to get fixed at the local shop.(...)

Unless the shop in question has been in the business for that long. When I started out two (three?) years ago, I had them do various work that was outside my comfort zone and/or equipment. It cost a pretty f***ng penny, but the work was always properly done.

As for the thread, everything has already been said, good luck to the OP.

I would not be concerned about the o-ring as I would be the shape of the tip of that mixture screw. If turning the screw makes no difference, it is apparent that it's not letting any fuel through. Could be a broken tip that is stuck in the port or could be a plugged pilot jet or simply clogged passages between the jet and the mixture screw.

Take the fuel hose and vacuum hose off the petcock.

Open the petcock in the prime position and check fuel runs out.

Put the petcock in the on position and check there is no fuel coming out of the vacuum hose.

Flooding on one cylinder (if it's flooding on no. 2 - I can't see anywhere that you mention which cylinder it is) can be fuel leaking through the petcock diaphragm straight into that cylinder.

Four things are certain in life; Death, taxes, faulty GS petcocks and faulty GS regulators/rectifiers and charging systems.

I think that adds up to five things:confused:.
