    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.

found that my petcock is damaged and have ordered a new one. Looking through my old parts from other bikes over the years and put on a non vacuum petcock. flows great for now. What happens if you don't plug that vacuum on carb #2, out of curiosity? Vacuum leak?
 
Do you really need someone to tell you not plugging it's a bad idea?:rolleyes:

I know it's a bad idea, but I'm asking why. Does it create a vac leak? Does it cause it to pull less fuel? I didn't ask should I, I asked what happens. :D:D:D

I've already plugged it, because I assume there's all sorts of stuff that can get sucked in, but I'm curious to how it affects the carb operation, for my own knoweldge.
 
Open vacuum port,yeah it's a giant vacuum leak.Will lean out that cylinder big time.Happy you did plug it.Worse case it could lean it enough to seize it.Overheat it for sure.

"Leak" usually implies something small. :o

I don't think the term would apply in this case.

I think "vacuum DUMP" would be more appropriate. :-\\\

One cylinder running like crap usually makes the others trying to compensate run like crap as well.

At least as he said it was a what would happen not a should I plug it question.
