    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.

curious problems with an 82 GS650

So I've been working on this new bike I got, and at first was only firing on two cylinders. The two left ones would fire, and I found replacing the igniter and one coil was the problem.

Now although the thing runs pretty decent, it seems to need a bit of a carb adjustment, but otherwise fine. (this is due to a very slight bog when you hit the throttle hard) I figured synching the carbs may do the trick (there isn't much problem here)

However Whenever I try to synch them up now, my tool shows no vaccum coming from the carburators, and I'm curious because with no vaccum, how is it running so well?

I hooked the tool up to my 550 that's running fine and there isn't a problem, it's showing plenty of vaccum...

a little info, it was sitting for a little bit when we got it, has about 19,000 miles on it. Compression was 8% change across the board (from 160-180).

So frankly, I'm stumped. Any help is appreciated.
 
If it's running, there is vacumn.
All I can think of is the way you have it hooked up,are the adapters screwed in OK?
 
oh yeah, totally. could it be that the boots themselves in between the carbs and engine are faulty? If that's the case it should hardly run at all, right?

I dunno I'm confused. I also wondered if the holes themselves were plugged for some reason, and that's not the case either.

oye...
 
Well yes you could have vacumn leak's in the boot's ,but it should still show some reading's on the gauge's.
You blanked off the vacumn take off for the petcock?
Take one of the screw's out of the carb boot's & push a piece of wire through to make shure they are not sealed off, people do wierd thing's!
 
yeah haha, I blocked it off, made that mistake with the first bike.


I'll try jammin stuff up onto the holes and see if that's the problem heh.


Thanks a lot.
