Starts stalls I have a 2007 Kawasaki 450r. It was running fine then After about 30 minutes it would stall no matter how much throttle was given when The clutch was released all the way. It would idle fine,, but progressively got to where it would stall after idling in neutral also. Brought it home and let it cool down. Tried to start it 30 minutes later and now will not even attempt to turn over. I've used the choke and let the engine warm up properly prior to riding. Just went to turn around and it just started stalling all of a sudden when clutch was fully released. Any ideas?

Contaminated or water in the fuel is most likely the culprit here.
drain the tank and carb (small screw at bottom of carb float bowl)
Add fresh fuel from a CLEAN fuel source. Best to completely drain your fuel can and fill it up with fresh fuel. That way if the fuel can is the culprit you eliminated doing this twice.
What happened was fuel sits on top of water, this is why the bike would still idle. The idle circuit in the carb pulls fuel from a higher point than the main jet. This is also why when you hit the throttle it would just die, it was sucking most like something other than fuel.

SOURCE: have an 06 Suzuki Katana

Not for sure but u might try to re jet the bike.i own a 98 suzuki bandit 600s and it also is really cold hearted. those bikes are unfortunately known for that problem.not that it was much help but u might try contacting Dales Holeshot Performance he specializes those types of bikes he also sells the jet kits.
i would also try to adjust the idle slightly higher hope this at least helps

SOURCE: stalling out

u have the mixture screw wound in to far. its normally located on the bottom of the carb. try winding it out half a turn at a time once the bike has warmed up. also turn the idle screw out a quarter of a turn at the time its in to far thats why it idles at low revs. the choke is needed to keep the air fuel mixture right thats why u are having to leave it on for so long. hope this helps.

SOURCE: Stalls to idle after riding for an hour.

It sounds like you probably need to replace the fuel filter, or you may have alot of trash in the bottom of your gas tank, possibly even water in the gas. If you can, take the tank off and clean it out well, making note if there is any trash in it, by emptying it into a bucket so you can examine it. Go ahead and replace the filter if you find any trash or water in the gas tank. If it is ok, then the next thing would be to check the fuel line for aging. Sometimes in rare cases, the hose gets old and weak and when you try to pull fuel through it, it can collapse and essential stop the gas flow, just as if you have turned the gas off, then when the suction is stopped the hose will open back up and appear to be in good shape. You can use your fingers and squeeze the line the entire length and see if it seems to feel excessively soft, if so that could also be causing your problem.

SOURCE: Honda 750 stalls if throttle is opened unless choke is on.

Hmm , sounds like a vacuum leak, check all the hoses, and the rubber intake manifolds and clamps

2007 Kawasaki STX 12 F running rough

Sounds like you might have some trash in the fuel system that worked its way into the carburetors. I would suggest having the fuel system serviced.

Kawasaki 450r

I had a similar problem on one of my bikes. Turned out a "Test Port" had rattled loose between the carb and the intake. I threaded a screw in the hole to prevent the leak and problem was resolved.

1989 chevy cavalier z24 strats but stalls rapidly

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Starts fine, Idles fine, Drives Fine for a while

you might want to chk. the crank sensor and or cam sensor. sounds more to me that it could be fuel problem. chk. fuel pressure. pump could be on its way out. don't be fooled by hearing the pump running as they sound like they are pumping but there not, at least not enought pressure to keep it running. pressure should be around 50 p.s.i.
