    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 have a 1981 gs550 and i have recently had the carbs rebuilt, cleaned and tuned to factory specs. My bike seems to not want to start on the first turn though! sometimes i need to hold down the button until it finally gets enough to get going. when it is going it runs ok but it seems to not like starting. Any ideas???

Mine's the same way. Once warmed up, if it sits for more than 15 minutes, it needs a few cranks to start. It starts with a little choke very quickly, though. I've also got a stock air/fuel system with factor settings. Maybe there's a small air leak somewhere. I'm living with it because otherwise it runs fine.
 
more than a few cranks

more than a few cranks

it takes more than a few cranks to start up though, it can take up to 30 seconds with it sort of running but needing the starter to keep pushing it through till it can run on its own. so i'm not sure if it is normal, it could be but i'm new to this whole motorcycle thing, this is my first bike.
 
check your battery. You might be suprised how much of a difference a low battery makes. Also could need tuned up (plugs/timing/carb sync).
 
put your bike on prime for a few seconds before you start to fill up the bowls, make sure its on choke and crank till it fires. its also alot easier to start whe bike is upright such as centerstand. tends to take longer on side stand.

Mine was a bit cold tempered, but a new battery and a $19 "Bell Juicer" battery tender from Wally World made a world of difference. I now start in a second rather than 5-10 seconds (when it was cold out or sat for a few days). I never thought the battery made such a difference, but it really does..

Yup, i had a bike for 2 years before i realised i had a low battery and was causing it to be a hard starter and always backfired. I just thought that was the way it was (my first bike). Battery finally died, got a new one and it was like night and day.
 
On cold starts try putting your thumb over the valve cover tube while pressing the starter button. It cranks over a little sooner and saves your battery from constant cranking. While it's idling reconnect the tube to the airbox.
