Loosen the fuel cap and take it for a ride. Don't take the cap off, just loosen it. You may have a bad vent in the fuel cap allowing a vacuum to build up in the tank.

Good Luck

It sounds more like a fuel problem to me. If I had to guess, I'd say that for some reason your bike has started to run lean. The lean mixture is causing your engine to run hot. The heat from the is "perculating" the fuel in your float bowl and causing it not to start. I've seen it before on race cars.

The mixture on your bike may be running lean for any fo several reasons. You could have trash in one of the jets in the carb or you could have a vacuum leak. I'd put my money on the later. There is a hose that comes off the backside and feeds vacuum to the VOES switch. Make sure this hose is intact and doesn't have any cracks in it. I'd also replace the intake gaskets at the heads and the carb seal provided the carb is the original CV carb.

If the carb has been changed to something else, there could be other problems as well. Also, make sure your not running gasoline that has a greater than 10% ethanol mixture in it. The greater the percentage of ethanol (alcohol) the leaner the engine will run.

Good Luck
Steve

It can also be faulty spark plugs or worn out spark plugs causing this.Also it can be low voltage battery.causing this.Disconnect the battery for 15 minutes then reconnect and check if its helping to reset the no start problem.Also check battery voltage.It should be 12 volts on meter. -------- How to test the coils on Harley Davidson Dyna 2002:-- The engine should be cool. There are two large coil terminals and two small terminals.Measure small terminals with meter set set on "RX1" and measure large terminals with meter set on "RX1000" First remove the two wiring connection on the spark plug.Just disconnect it.Then remove the small connections on the coil.This connections are screw tight.So remove the screws. Now with the meter measure the ohm reading.The reading between the two small connections of coil terminals.The reading should be between 2.6 to 3.0 ohms.----------- Now measure the large terminals.The reading should be between 10000 to 12500.If the reading is not between this then coils are faulty and coil pack needs to be replaced. ------------ How to test crank sensor on Harley Davidson Dyna 2002:-- The crank position sensor is located in front of the oil filter on the left side of the engine in front. Put an oscilloscope on the sensor leads and spin the engine. You should see a pulse coming from the sensor.The CKP sensor has a B+ power supply, a ground, and a signal circuit.As the crankshaft rotates, the wheel teeth interrupt a magnetic field produced by a magnet within the sensor. The sensor's internal circuitry detects this and produces a signal which the ECM reads. The ECM uses this signal to accurately measure crankshaft velocity which is a variable used in order to detect misfire, spark and, fueling.--------------- Find the wire that goes to the B+ Measure from this wire to ground for the DC supply voltage. Measurement should be taken on the sensor side of the connector. Ground connection as well.On Dyna 2002 this wire is marked BK for Black. Do this test at rest and with the engine spinning. A loose connection could break as the motor shakes.If you have voltage present with the key on and with the engine spinning move the positive meter lead to the Signal wire. This is marked R for Red on 2002 Dyna. With the engine spinning you should see a voltage signal on that wire. You should measure the signal at the sensor connector and the ecm to verify it is reaching the brain.-------- Also with meter you should get this reading on crank position sensor:--- constant 5vac with the plugs out and 3.2vac with the plugs in.If this is the reading you get then its proper crank shaft position sensor.But if you get contact 5 vac with or without plugs in then its faulty crank sensor. ---------------- For ignition module testing check for the 12 volts on main ignition live wires.If its 12 volts when key is turn on and no volt when its turned off.Then its proper voltage and good ignition module.But if its 12 volts in both on and off then its faulty module causing this problem. -------------- This should help.Thanks.Helpmech.

I would run the fault codes and look for a temperature sensor. It will also show up a faulty crank/cam position sensor and TCM fault as well . I would stay away from the transmission replacement idea until I was sure that the transmission was the reason for the overheating or hot stopping problems. To set your mind at ease have a pressure test done on the transmission to check for internal problems

Runs fine until it gets warm or hot then cuts off then cools and will recrank


Does it crank over when the engine is hot. If it does sounds like your maybe loosing fuel if so check fuel pressure if t is good check for spark could be a bad crank sensor or bad distributor.

Is there a heat shield on the starter


I don't think there is a heat shield on the starter but, I wouldn't think that would be you're problem. I would try changing the ignition module. It's on the engine block, drivers side, I think. Usually when they are going bad they will shut off engine when they get hot. It won't crank until it cools off. After it cools engine will crank and run good until it gets hot again. Good Luck.

It's a sensor. I had one that was cracked. When the car warmed up the heat caused the crack to expand and the sensor wouldn't work. After the car cooled it was fine until it got hot again. The sensor is probably gone for good now. You would need diagnostics or troubleshooting to determine which one. You can get a hand held diagnostic computer for cars. Some auto parts stores check for free. You could see if any does a loan-a-tool.

do you mean wont crank over and start till it cools off? if thats the case it sounds like you got a bad crankshaft position sensor,,thge sensor is fine when its cold and warm but when it gets hot it goes open and the cars computer cant see the rpm and shuts the engine off,and then when it cools off the sensor works again and the car starts and is ok till it gets hot again,if thats the case thats what it is,,,hope this helps,,,about $100 for the part
