keeps dying after 20 miles

So I was riding down the road when I suddenly lost power. I pulled over and tried to restart the bike but it will only start if I have the throttle all the way open and while I have the starter engaged. Then It immediately dies. I think it is flooding because I can smell fuel and there is some grey ish smoke coming from the exhaust. Also if I leave out for a few minutes it will run few seconds and then die again. This happens the other day and I took the carbs apart and blasted everything with carb cleaner and the problem seemed to be fixed but after another20 miles the same issue arose. My guess is a tiny crack in the floats. Anyone else think the same?

Could be a stuck float, dirt/rubber in the needle valve.

Make sure the oil hasn't filled up with gas.

The oil level is correct. I made sure to check needle and I didn't see any build up or anything. The floats did look sun dried. The hardest part of this is how to tell if I've fixed the problem or not.

Pretty sure it's not vapor lock. The first time it happened I left the gas tank open for about twenty minutes and it would still do the same thing. This site needs to stop saying poogs and switch to vapor lock. More people will know what we are talking about. I have experienced vapor lock before and the engine is not acting like it's out of gas.

Dear guy with 13 whole posts here. POOGS is not the same thing as vapor lock.


Vapor lock is a problem that mostly affects gasoline-fueled internal combustion engines.It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling. Restarting the engine from this state may be difficult.

POOGS is caused by a block in the gas tank vent that keeps fuel from
flowing properly into the carb bowls. Basicly the same thing as putting your finger over the end of a straw keeping liquid from flowing out the end.
NOT the same thing.
