    All new forum registrations must be activated via email before you have full access to the forum.

    A Special Note about Email accounts!
    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.

AT MY WITS END. The bike was on a spin and covered 120 miles, running like a clock. Suddenly a gradual loss of power and a cut out. Refused to start. Got her home. Checked ignition, sparking on all 4. Fuel in fuel filter under tank, tank not air locking. Bike started but only revving to 4000rpm, completely flat after that. Bike will rev fully when aerosol sprayed into manifold, indicating fuel starvation.Tried an alternative fuel supply, no change. Removed carbs, found nothing, cleaned and blew out, just in case. Refitted and problem still there.
ANY IDEAS??????????

Did you look at the spark plugs? It's possible that a float stuck and you fouled out a plug. If so, replace the plugs and check your oil for a gassy smell.

Otherwise, your symptoms sound like a fuel delivery problem. Did you switch to "reserve" just before the problems started? Try removing the fuel filter.

When replacing the carbs on a 650, I loosen the battery box too to get a little extra room.
