Gas Dripping From Tube Behind Front Fairing.

[uechi kid]

I have gas dripping from a tube behind the front left fairing.

It's coming from what looks like a feed line for the carburetors.  Anyone know what's causing this and how to fix it?

Most likely is a stuck needle valve or debris in between the needle and the seat that is not allowing the float to close the valve fully.

Some times a dose of Seafoam and a good spirited run will clear that up if it is minor. If a dose of Seafoam or carb cleaner does not fix it, you probably in for a carb overhaul.

I am pretty sure the are posts in the tech library to help with this issue.

Thanks.  I’m giveing the Seafoam a try.  I’ve never taken a carburetor apart so I’m a little nervous about having to do that.

Seafoam didn’t do the trick, so I guess it’s time to explore a carb rebuild.

Bang on each bowl with the handle of a screwdriver. If that does not work you just need to take the bowl off and make sure the needle valve seats.

I hate to sound so ignorant but, can you point out the float bowl and drain valve?  And do the carbs need to be removed to do this?

Thanks.

Seafoam although a good product often does not do the trick. Best get a spray can of carb cleaner and spray the whole can into 1/4 tank of fuel. Once installed start the engine, run it on choke for a bit, then let it run for about 20 minutes every once in a while running the rpms up to 2000 for a minute or so. Shut it off, let cool and do it all again. 3 times is good. Now fill the tank and go for a ride keeping the rpms up. Could be a problem solver.

Use the spay carb cleaner rather than the stuff similar to sea foam that’s designed to go in the tank?

That's what I use, seems to do a better more thorough job.

Use chevron techroline in the tank. SeaFoam is junk, and does Foam everything it touches. You need to remove the carbs and replace needles and seat on bad carbs (I think 2 carbs use that hose). It's alot of work. The problem may be the o-rings on the seat itself, which should also be changed. Check all jets while at it. It looks like this
