So just like the title say Im leaking gas out of the side of my carb I believe. I tried a search but Im not sure what to look for and my internet is slow as crap! Its when the gas is left on it has a small drip out of the side of the carb. I ordered the Orings for it. My main question I was curious about is it ok to ride it like this while waiting for the part? I haven't been riding it since I found it. Also is it hard to fix by my self or should I have someone do it for me. I think its coming from this side of the carb.

Anyone help me with this. I have read several thread stating a float may be stuck. But I'm not sure? Any info would be helpful.

Where exactly is the gas coming from? Is it coming out of the hoses on the carb or somewhere else?

I think it is coming out of the side of the carb.. But I need to take some things off to see if it is coming out higher. It is on the side I took the pic but I have not been able to find exactly where yet.

I think its at the spot bolted together right under the lower brown tube.

The most likely cause of a leak in that area would be a torn accelerator pump diaphragm. It's fairly easy to replace without taking the whole carb apart.

Carbs are not particularly difficult, but they do require good mechanical skills to tear down and reassemble them without damaging screws and such, and very careful attention to detail.

I will have to look into that. Thats not a piece that comes with the carb rebuild kit is it? Should it stay parked and not started till that is fixed?

Yamaha doesn't sell rebuild kits, so I don't know what's in the kit you got from wherever it came from. Probably not.

As far as riding it, your engine gets hot, and gasoline is extremely flammable.

Oh I haven't been riding it. I bought all the orings separate that yamaha sold. I dropped it off with a buddy to look at. I know all about how flammable gas is (Im a fireman) But its the vapors that are the most flammable :thumbsup: I think your right about what part though gray, the leak is coming from higher up after we looked at it a little more. Thanks for the help! As you can tell I dont know much about dirt bikes so all the info is appreciated.
