You didn't say what type of bike you were having a problem with but it sounds like a classic case of "fuel percolation". When the engine is hot and you shut it down, the lack of air flowing by the carb allows the fuel in the float bowl to boil. This floods the engine and it won't start.

Now, to determine exactly what's going on, The next time it does it, have a spare set of spark plugs with you. Pull the spark plug wires off the plugs in the heads and put the spare set in the wires. Ground them good on the engine and press the start button. Watch for the plugs to fire. If you see spark, then you know your problem is fuel related. If not, it's ignition related. Then we can go from there.

Tell me what type of bike we're messing with here?

Got spark got gas want fire at all


chances are the carb is not set properly. turn the screw on the carb all the way in then back it out 1 1/4 turns. as a trick you can spray WD40 in the carb to start it too. if you can get Either, that works best. you may need to adjust the screw to get it to run at peak performance. adjust it in 1/4 turn increments.

Honda shadow vt1100c 1986 idile to low after running awhile


There's an idle adjustment screw. The bike runs faster when cold because the fuel\air adjustment is richer on a cold engine. When the bike warms up, the fuel becomes more lean in mixture because the heat causes the fuel to expand, i.e., less molecules of fuel to the firing sequence of the piston. When the bike is warmed up, after say ten minutes, the heat causes a leaner mixture, so adjust the idle on a hot engine (about 1000 rpm more or less). The bike will idle faster when cold, then drop rpm's as the engine warms up. Good luck

Battery is charged, Starter Whines and is turning but bike won't fire off, 2009 Street Glide


is your engine turning over, if it is, pull your spark plugs and clean them. this happens on my 98 Heritage Softail Classic. It sounds funny but from long warm ups with choke pulled they get carbon build up and this keeps the plug from firing. If your motor is not turning over then you Bendix gear is out on your starter.

My suzuki lt z400 won,t start with switch ,but you can push start!


I would suspect the choke. Is it automatic? If so, it may not be active. So you are basically warming the engine the hard way. Seems like that would be the first thing to look into.

1200 custom sportster stops running when it get warm


Sounds like it is possibly the cam sensor. It is located under the round cover on the lower right side of the engine. The cover is held on by 2 rivets. If this is indeed the problem, you will have to re-time the bike after replacing the sensor.

Is my motorcycle fuel injected or carburetor? when trying to start my bike at a cold start it takes awhile to start. it sometimes back fires and makes a wierd sound.


irt is carbureted and all bikes dont like to be cold sharted you need to wait 3 min to let it warm up before you rev or leave on it. do you live in a humid/colder climate because that can have alot to do with the early morning and cold starts

How do i change the collant in my 1994 cbr 600 f2 my coolent is all souping right now


remove seat, turn fuel selector off, pull off fuel line to fuel filter, remove tank, you should see radiator cap now... turn loose not off, just incase still has pressure... now follow lower radiator hose and it will lead to the water pump and on the water pump there is a little screw on the bottom sticking out of the side...thats the drain for the system ...now place something to catch a lot of fluid and when you take the drain bolt out it'll start coming out but as soon as you take off the radiator cap it will pour out fast so be prepared. that bolt i think has a washer on it to, don't lose it...once drained, put drain bolt back firmly dont torque stand the bike up on a wheel stand and now slowly ever so slowly start to pour your coolant: coolaid, waterwetter, whatever, but not tap water. now jiggle the bike around once in awhile to get trapped air out of it it, may look full but you might have to get a stand or box about waist high set your tank on it and hook up the fuel...be careful dont let the tank fall, get someone to hold it for you...start the bike let it run for a minute shut down add more coolant, start it again run it and jiggle the bike watch to see if water bubbles are still coming out now rap the throttle up to about 4000rpm once or twice check the level again turn bike off let it set for a minute again, does the level stay now right up to the neck.... well then put on the cap and everything back on.. now when you have everything back on take for a short ride and then check your coolant reservoir, dont overfill it just up to the warm mark and you should now check the drain bolt for leaks...all done.
Can i get a very helpful reply....thanks

Kawasaki GT 550 - erratic tickover


Put a carby kit through it and clean, inspect and blow all ports through, check intake rubbers for any leaks, (pin holes can change air fuel ratio) Especially check for obstructions in your idle/bypass jet, do the kit first so you know its right, then tune your idle mix until steady.
