Well, I tested it this weekend with not very good results. After about 10-15 mins of riding it shuts down. It won't start up after it shuts down until I wait about 10-20 mins. Then acts like nothing ever happened. When it shut down, I had about 1/3 throttle and the engine just cut out. I was on a flat surface so no bumps to bounce any wires, but it acts like some one just hit the kill switch and turned it off.
spark is ok flywheel is ok fuel is pumping battery at 13.7v grounds are still ok
Is there a way to test the coolant temp sensor to see if it is sending faulty info to the ecu?
When an ecu goes bad what does it or doesn't it do?
There is a way to test the temp sensor on the head. I have to read the wiring manual to give you better directions, but I think the manual can be found online here in our tech section.
The ecu could be bad and still work there is no real way of saying yes I have a bad ecu unless you switch it out.
anything is possible.
One question what makes you think it is due to a faulty heat reading. Could be a bad wire in the harness to. Reason I ask is if the fan isn't running then it may not be your problem.
when it shut down I stuck a thermometer in the radiator and it was at 160. The impeller was just replaced last month. I am going to pull the cover tonight and make sure the bleed hole is not cloged an make sure that the impeller is on tight with the washer behind it. I am also going to change out the ecu with my other bike. well see what happenes.
you can start it right?????......go start it and let it idle for like 5 minutes.....and touch the radiator....if its still cold like the engine never even ran...then you have air bubbles in your lines...ive had this many times when changing coolant and stuff. And yes check the big bach of wires and those connections....you dont need bumpy conditions for them to act up....sometimes they are jsut loose from the begginning. CHAD
i'd recalibrate the throttle and the TPS. Have you rerouted your fuel lines? I had a similar problem it stalled about mid throttle like it was out of gas. I shielded and rerouted my fuel lines and reset the throttle and checked the TPS and it has run great for the last 2 yrs.
Originally posted by 440rider also check o rings and fuel filter. Is your stator sheilded? I also had a prob like that because my stator wasn't sheilded properly.
by sheilded do you mean the plastic sleeve that goes around it? don't know I ordered a flywheel puller over 2 weeks ago and have not recieved it yet. I ordered one from haydug on friday and should get it tomorrow. I will check then.

did you have to wait 10 mins. before it would restart? also I don't have a d&m kit. Anybody near DFW Texas have one?
