    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.

hey am pretty new to this and i have recently received a 1980(i think)gs450l from a friend. the bike was very nearly a basket case and after a bit of a rebuild it now runs, unforunately it runs like a sack of spanners, idle speed is fine but as soon as i open the throttle even a fraction it starts running rough and backfiring through the left hand carb any help would be greatly appreciated thanks
 
Did you dip the carbs and install new o-rings? Also check the valve adjustment. Forum member Steve has a pretty awesome spread sheet for doing the valve adjustments.

been through the carbs and had them double checked by a friend, changed the o rings and checked valve adjustment all ok :confused:. been told by another friend that it may just be down to the airbox and if i fit a set of filters (that he provided free of charge) it may just rectify the problem, is there any truth in this

You've been through the carbs ? You mean you dipped and cleaned them ?

Did you adjust the valves ? How do you mean that they're ok ? Why the question mark face ??

If you install pods, re-jetting of the carbs will be required.:)
