Question for you guys. I have a 04 crf150f and noticed today there was gas dripping out of the black tube hanging from the bottom of the bike. I went and bought some sea foam to clean out the carbs, and there is no more leaking now but the bike will cut off immediately when I don't give it any gas and just letting it idle. Any ideas what the problem could be?

Bump for a answer

It sounds like float level. I had something similar on my crf80, I tried a couple simple solutions and none of them worked.

I had to pull the carb and do a complete rebuild (clean up) and reset the float. Problem solved, runs perfect. Actually better than it has since the day I bought it.
There can be dirt, gum or grime that you can't even see and it will effect the way it runs.

Also use a air compressor and blow the carb out with a air hose after cleaning.

Sounds to me that in the start you had some trash in the needle and seat area keeping the fuel from shutting of when the fuel bowl got full therefore draining out of he float bowl overflow hose. When you sea foamed it you cleaned the trash out of the needle and know it sounds like it got stuck in the pilot jet. If the pilot gets stopped up it won't idle but will run off of the main as long as you are giving it some throttle. Remove the float bowl give the entire area in there a good cleaning with carb cleaner also remove the pilot jet and inspect the orifice to see if it is stopped up. It is a tiny little hole so hold a light on the other end and see if you can see light thru the opening. Clean it out, blow it out, or poke it out with a torch tip cleaner or something. I'm pretty sure this will solve your problem. Been down that road many times. I put a fuel filter in line on most of mine to help keep trash out of the carb.
