    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...

    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 just put my 83 GS650 back on the road after 13 years, (long story) short version below, but I resurrected it. It has half the power it had when I garaged it.
How do I get my power back or increase it some more (I dont have deep wallet).
I completely rebuilt carbs due to varnishing and sync'd-em. new battery and she cranked. I had her to a buck20. I mean 65, but it lacks the accel it had... please reply with ideas

Story
I thought the front was toast, LET SOMEONE ON IT, IT NEVER CAME BACK WHOLE, they made it 100 feet though, they thought my guards were brakes but no braking, threw bike, intraments first into curb, forks and handle bars pointing to different compass points. figured a couple grand to fix. My buddy gave me a running 82 650 for parts, stripped the instraments and loosened fork bolts and my buddy said twist this......and cranked on the handle bars and tire, BOOOM.. IT LOOKED STRAIGHT.
I clamped the wheels and cranked the bolts down, goes to 120/65 no a hint of a shimmy. WOW, I never reallized how much I missed my GS.. SHE'S BACK

thanks
 
Seeing as the bike has been sitting for so long it may just need time to loosen up again, give it a full service (plugs oil change etc) and treat it as if it being run-in and then go from there, a couple of hundred miles may make a lot of difference.
 
Also, since you had the carbs off (and you DID replace the O-rings...) check for vacuum leak, this can cause a low power condition also
 
Thanks so far

Thanks so far

Thanks so far,
I did NOT change the carb 0-rings YET, just got two kits in, and re-building spare carbs now, I did silicone o-rings while rebuilding. Only 10k on bike and no dry seals..
I never heard of re-breaking in the bike but sounds logical. It was rough idling but is smoothing out nice this week (400miles later).
I changed all fluids and filters, plugs, but still need to check points, yet.
Can condenser or coils go over time sitting ???
Thanks, Bob
