Hey guys, Im new to this form and new to being a cb750 owner. I've been reading and educating myself as much as possible. huge fan of these bike.
I have a 73 750 and I got a great deal on it. it runs pretty decent gotta sync them carbs and a few odd and ends. my question is on the carbs you have the 2 fuel feed nipples, above them more so in the middle theres 2 more nipples, what are these??? should something be hooked up to them? Im sorry if im putting this on the wrong page.
any info would be great guys!!

Hey matt, welcome.
Just an FYI, its bad form to ask your question on another's thread.  It changes the subject from what the original poster intended.  ;)
start another thread, and others will chime in.    ;D

This would be the bowl vents. They should have short rubber hoses on them that vent up around the airbox. If you want your post to get more views, start a new topic! :D
