    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.

I put new plugs and new coils in it, but that didn't help. Sometimes it regains all power while i am riding it. Runs ok for a few minutes... then back to half power. Does not seem to be heat related. I am new to riding, any suggestions?

Sound like your fuel filter is plugged. Try changing that.
 
There are a couple of other areas to consider.

The fuel filter is one - both any inline fuel filter and those on the inside of the petcock and inside the tank. If the tank is rusty inside, the crud can build up on the in tank filter or in any mesh screens inside the petcock (not sure if this model witll have that or not).

Another often overlooked area is the gas cap. The inside of the gask caps have a small vent hole - these can get clogged (remember how tough is it to pour gas out of a gas can when the little breather hole is still plugged?). This is especially true is the tank has been sealed... If you are running the bike when the bike starts acting up, open the gas cap and see if air rushes in.

Another issue can be using too small a fuel hose or having a kink in the hose. If you don't have clear fuel hose, replace it to get a better view of the gas flow.
 
thanks

thanks

It seems I may have had a couple issues...I bypassed the fuel filter and that helped some...Then I took the carbs apart and sprayed them down and now I'm doing 60 in 2nd gear! I will check for rust in the gas tank also.
