Last weekend we picked up a 2002 MXZ X 800. I know its a racing sled made for the low elevation flat lands but we ride the mountains so our issue is this:
We need to find a way to get it to start and stay running at higher altitudes. When we're at the parking lot 7-8,000ft she will fire right up and run just fine. But once we get her up around 10-11,000 ft she dies out and will NOT restart.
Yesterday she got stuck in about 4 ft of fresh around 11,000 ft. Couldn't get her started again, checked the plugs and they were not only black (just put new ones in last week) but they were also wet, which makes me think that whatever senses altitude is not doing it's job since it's flooding the engine with gas and not pulling in extra air to compensate for the thin air at that altitude. I think it may have to do with the MPEM box, any input would be very helpful.
I have experience with Polaris and Cats, but Doo is a new animal to me. Thanks in advance!!!
