Any ideas why this machine runs real rich? did they have mproblems with injectors or somethig? Am i missing something? Any help would be appreciated.

 

make sure the asir filter isnt plugged or any vent lines. if not maybe the t bap sensor is bad causing it to go rich. check for any codes it might have.

 

Air filter looks good. Wonderin if it ain't injectors. that is the code that comes up. code 51. not sure i tried different plugs. they seemed to help but not last. got rid of champions and went to ngk.

 

If the code is telling you "injectors" than it must be an injector problem. Does your manual list several possible problems? My quad is totally different but a code 51 can be 4 different problems with injector #1 for cylinder #1. Code 52 would be the other side of the engine. If it CAN be multiple problems pick one, like a short circuit, check it and try to eliminate as many as possible.

 

I talked to a local mechanic, and he said sounds like a power inverter or something loike that. he has 3 quads at his shop waitin for them. they r back ordered for a couple weeks
