i am not here to bust balls, riding this weekend was pretty good for me. but for my brother different story. he had the ecu reflashed, thought he was good to go, wrong. first 2 days sled ran fine.on our way back to camp sled quit, let it cool a little would start for two minutes then quit again. did this twice and then realized it was hopeless. backfiring like crazy. havent had a chance to look at it in the daylight yet but am thinking or hoping its a wire melted or something simple.we all ride cats six of us except one who rides a skidoo. well needless to say he wanted to do the towing, we let em but did not take pics as requested. will post what we find.
