Hey guys, I'm really near the end of my rope here. I have a 2002 Polaris 500 HO RSE.
The issue: Once warmed up (not cold) half way through the throttle range it acts like it's overfueling and hesitates. I went though the fuel system treating the symptom unsuccessfully unitl I checked the timing. At the same time it starts hesitating the rpm's drop by half and the timing light flickers erratically.
From what I understand the ignition fires twice, if this is the case then my question is does it do this all through the throttle range?
So far I've switched out the coil/cap, spark plug and cdi box, no difference. Compression is good - 85 Psi, 60 Psi on the first crank.
It has also been pointed out to me that it could be going into 'limp home' mode due to perhaps an overheating condition. Are these machines equipped with this?
I'm desperate as I need the quad for hunting next week. I appreciate any insight or perhaps a thread where this may have been covered before. Thanks, Andrew
