Why does the bike starts, runs, but after warmed up will not restart till it cools down?

SOURCE: '01 GSXR 1000 won't start at temps above 170 or so.

Check the coolant sensor.Probably reads to the ECU that the engine is cold while it is not and the ECU injects more fuel that it should.Unscrew the coolant sensor (it is located on the cylinder head or on the thermostat casing) and boil it in water and measure it's resistance before (cold) and after boiling it (hot).It should not be the same.

Mine has the same fault. The ignition sensor leaks to earth when it is hot so engine cuts out. I've had two sensors fitted. But They still leak to earth. Trying to get Suzuki to sort, permanently.

Overheating. The raditor coolant or the cooling fan is'nt working corectly the engine should be as hot as it's going to get in 5 minutes then the therostae opens to start keeping it at the same temperture if the coolant or the fan can't keepit at this temperture it'll not restsate till it's cool enough to be in the safe range agin. Some times not changind the oil often enough can case this problem too low coolant and the fan not working all can cause this after finding the coolant system problem and fixing it change the oil as it'll be ruiened from the overheat. Low speed hotrodding and stop and go traffic can trash the oil and just a few hot runs acan make it need and oil change as the oil fails at high tempertures and the oil is an important part of the cooling system as it's cooler beng clean and in the air flow. As the oil cooler doesn't have the benifit of a fan sitting running and hotrodding at low speeds will heat and kill the oil then after the oils killed then it'll overheat case the oils bad.

coils can expand and lose internal connection when hot.you can test the coils cold and then heat them with a heat gun and see if you loose continuity.
