Last winter my m8 motor decided to go clankity clank and leave me stranded in about 3 feet of fresh powder 10 miles from the trailer.
After I got it home I dug into it and I was shocked, but impressed. I had never seen this happen before.
I just started the rebuild process because I had a bunch of projects to get to first.
Before I rebuild the whole thing, I would like to hear some ideas on why it happened in the first place.
Concerns:
1) I am not sure if it overheated (I have dual Koso EGT gauges and coolant temp, BUT.... the gauge shorted out and would not read anything the day before after a quick power-wash) Maybe it was taking power from fuel pump? I have never had a problem with high coolant temps, and EGTs only get too high if you cruise on the trail without varying the throttle.
2) The Mag side head and plug has never looked like this (What is with the thick black glaze?)
3) Could a bad PTO seal cause this? Bad injector? Stuck power valve?
4) I do not have the stock m8 gauges so I am not sure if it threw any codes. The ECU was tuned by Speedwerx and the arctic cat race team.
5) Anyone want to buy a rolling chassis (2008 sno pro 600 with 158" track, m8 skid, custom tunnel, etc.) Kidding, kind of.
Here are some pictures for your enjoyment.
Thanks in advance for any ideas before the rebuild!
