there still working on it .

 

Has this bike been fixed yet ?

If not, I would like to arrange to see it.

Does it foul the plugs when cold or hot or both?
Has Leaders checked the fuel pressure.
Several of the main sensors could cause this problem. (Coolant Temp, MAP, IAT) depending on when it happens.
TPS Initialization is definately a possibility and the most likely cause.
Are you getting black smoke?

Lots of other questions to be asked.

 

Guess the question of hot/cold would have been obvious had I read the title of this Thread.

 

well they worked on it and said the tps was out of whack its ok as long as you dont get on it cold but it's back in the shop with a bad belt it has 57 miles on it.

 

Not surprised that the TPS Init was the cause, but I can't say I agree with the part about not "getting on it" while it's cold.

The plugs should not foul out under any but the most extreme circumstances. If a new set of plugs fouls out again, I would say there is still something else going on.

 

He says it is out of wack, but did he fix it? Or did he just tell you not to get on it when its cold.

Setting the TPS is actually something you could do yourself with a DVOM and some instructions. I would suggest you take DSA up on her offer to look at it, if your dealer has not fixed it. You will not foul plugs if the thing is working correctly.

 

Temp Sensor is the problem - we fixed one today the sensor is reading to high making the quad think it is warmed up already.

GM had this problem too lol maybe they sold polaris their temp switches..

 

what model GM product had this problem?

 

Mid 90 models with TBI injection

 

What do you mean by reading "too high"? The temperature or the actual resistance? If the temperature is reading too high, this would lean out the system, because more fuel is added at colder engine temperatures. If the resistance is "too high", that could be the problem, since the sensor resistance goes down as temperature goes up (i.e. cold temperature=high resistance).

Most likely a bad temperature sensor (and I assume you mean the coolant temp not air temp) will result in a code being set. But if it was just reading the wrong temperature two things are likely: 1) coolant temperature reading is MUCH lower than actual=more fuel added and could foul out plugs 2) coolant temperature eading is MUCH higher than actual=less fuel, should only have impact on first few minutes of operation after a cold start, will likely have a complaint of stalling after start.

The air temperature sensor will have even less effect on the system.
