Two Non-used Connectors on Carbs

[Guest]

So I'm not sure how to word this, but my 82 GS750E carbs have two black holes that look like they use to take a vacuum hose, but since there are air filters on them, they don't have anything on them at the moment. Should they both be capped off? Are they for vacuum lines? I tried to cap them off, but then the bike wouldn't start. So apparently it didn't like that. Here are the pictures I took:

Bowl vents. Leave them open.

Gotcha, I guess that makes sense why it wouldn't turn on when plugged :P Just wanted to make sure it wasn't a problem!

There is supposed to be tubing running from them to down between the swing arm and tranny...same as with the bowl overflow drains. Trim the ends off about flush with the bottom of the engine.

Without the airbox most people just leave the tubes off, they run better.

I am sure someone has already supplied you with this link. Go there and sellect the right one for your bike..8 valve or 16 valve. It has directions on all the things you are asking about. I even do believe there is a cable and hose routing diagram somewhere near the end.

Yes, exactly...
