    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.

Vacuum line plugging

I am about to install a pingle petcock and wonder about the technique used to plug the vac line. Do I plug just the #3 line or all of them? Should I plug the hose(s) or plug the inlet on the carb(s)?

Thanks!!
 
The only carb that should need a plug on the vacuum fitting is the one supplying vacuum for the petcock. That is unless for some reason the other three aren't already plugged.
 
I am unsure if the others are plugged, however all three(#'s 1,2,and 4) have lines coming from them that route behind the air box.
 
I know that the #3 is the only line that is "active" in applying vaccuum so that makes sense. Should it be plugged at the carb or at the end of the line?
 
Either method of plugging will work. The cleanest method is to get some plugs from any auto parts. Otherwise just plug the old line with a golf tee or something.
 
I installed a pingle on my 1100e three days ago (great valve BTW). I plugged the vacuum line from carb #2 with a 10mm bolt that I had coated with vacuum grease. I left the other two lines, a vent line and an overflow tube, alone.

Works great.

Hope this helps,

Jeff
 
kevin, just plug the vacuum line. The other 2 lines are the floatbowl vent tubes. If they are plugged or even kinked, the bowls will not vent properly and you will experience fuel starvation. They should be routed under the seat or any place where they will be in the clear. Bikes with stock intakes should leave them on. Bikes with pod filters should remove them to help the venting cope with the increased intake.
