Have you cleaned the carb out could have some crap in there. Or need a new plug.

Does it have gas in it lol, just bugging ya !

check valve clearance, it should be .003" if memory serves me correct.....also when it does quit, shut the fuel petcock and crack the carb bowl drain and make sure there is fuel there, the screen in the tank often plugs up and won't flow enough fuel to keep the bowl full

Maybe the diaphragm in the carb is dried out and cracked. Sounds like a "not getting enough gas problem" to keep it running.

my 250 sx did that if it got water in the fuel. If I dumped a little gas line antifreeze in the tank it would run perfect again, might be worth a try.

sounds like its running out of fuel.check tank bowl.make sure the gas cap is turned on.

Does it have the valve on the gas cap. Try turning it half way between the open and close position.

You could go and buy a inline spark tester at p.a for 6 bucks why waste time on fuel if it is electrical....or vise versa. Clubplug has platinum spark plugs, make sure you start with a new plug.

That could be it. One if my trikes would quit running every now and then, if I took the gas cap off it would start running again.

Yep four of my five trikes would do this. Tank would airlock. All I did was drill a little hole under the on/off switch in the gas cap. Just had to vent the tank. Try riding with the cap off first to see it it helps before you drill it.

No response yet. How long does it take to remove your gas cap, pull your tank off and clean it, change your peacock and filter, get rid of an aftermarket carb, change your stator coil, check your primary coil for breakage, change your spark plug and check for shorts which can take time.

my trike is doing the same thing, its as thou it cuts out as it gets warm. I wish I was home to sort it out.
buddy rolled his trike 2 years ago and crushed the top of the tank pushing the cap in. it couldn't vent and would do the same thing.
let us know wot you learn ...

THANK you for all the great info, i think it was an airlock now it's seem to be a-ok good for another 29 years lol

Thought I would throw up some trike pics. Me and my buds love these death machines.
