Posted October 6, 200915 yr hi guys -- can anyone please tell me what these 2 ports on the carburetor (marked 1 & 2 in the pic) are for, and what is supposed to be connected to them? a friend thought they were both vents of some kind & just needed an open-ended hose "whip" attached to them, but he wasn't positive. the fuel inlet line is on the other side of the carb and a much bigger barb. any ideas? also -- is the plastic fitting marked 3 in the pic some type of crankcase ventilating elbow (akin to a car's pcv valve) & the hose attached to it is supposed to be left open-ended? thank you for any info you could offer.

Like you say connect an open ended tube on them and run it down between the swing arm pivot and the back of the engine.3 is as stated a breather for the transmission, treat the same as the others. ...Paul
October 6, 200915 yr Author thanks for the reply, paul. do the open-ended hoses on the 2 carb vents need to go uphill above the carb a certain distance before heading downward -- to make spillage more difficult? my friend mentioned something along those lines, but i'm unsure if that's correct or not. thank you!

The only oneyou could get'spillage' from is the overflow and making that more difficult is defeating the object, it would then overflow into the engine! so the short answer is no
October 7, 200915 yr Author thanks again, paul! hopefully, we'll be able to try firing it up within a couple days (then we'll find out what else needs work on the bike, that we weren't aware of!)
