I don't remember exactly where that line runs but it is not the air box drain tube. I don't remember if it's supposed to be capped or connected to something. It's not one of the breather hoses that creates vacuum for the gas tank... Cap it off and see what happens. And someone who still has the bike, check to see where yours leads.

In pic 1 that I uploaded, you can see the hose and its attachment to the carb...{upper left}. It runs from the carb along the top right side of the airbox and turns down dead ending near the bottom of the air box. If the hose in my pics isn't the mung cleanout for the airbox, what is it and where does it go?

If I remember correctly, that's just an overflow line to drain excess fuel from the carb.

You mean like when the carb floods.....to keep it from filling the crankcase? The line im holding in the pic ISN'T the bowl drain on the bottom of the carb. Just wanna be sure of what your telling me bro. Thanks.

Yes, in case it floods. There's the line at the bottom with a screw to drain the carb manually, but the one on the top is an overflow. I could be wrong, but that same hose is not attached to anything or plugged on my bike, just dangles under the air box, and the bike runs fine so I have to assume that it is just an overflow.

More idling issues

TrevorG is right. The small line in the upper right, by trottle cables goes to petcock. Since you changed petcock, close that one off. The upper left is overflow. Then there is the bowl drain hose. I then have hose at front of carb. that goes down to a canister on frame. The only other hose is the gas line from petcock to carb. Hope this helps.

It did help. Nailed down each and every line and hose perfectly. Thanks to the members here.

The three screw in jets in the carb......they don't get O-rings, correct? Man, Im stumped. This bike warms up and the RPMs come down and it dies. For the life of me it acts like fuel starvation. I tore apart the gas cap to make sure it isn't a plugged vacuum equalization hole. Thing is, it takes hours before it'll start up again once it dies. Far longer than you'd expect either from an overheating issue or a fuel starvation issue.

All the answers and posts Ive seen here touching on this don't seem to account for that excessive time factor before it'll start back up. And when it does start, it fires right up on one touch.....no choke, no throttle.

So from bone cold, you can thumb it once and it will fire right up and run. It will idle and operate just fine until it gets warm, then it will idle down, die and refuse to start after that for this long period of time, right?

And when it does this, how long does it run during this "warm up" phase?
