Bringing back this thread - she's dead again!
Got a few hundred miles on it before it went back down. Dealer told me it was idling rough but taking throttle just fine, recommended new plugs and run it a bit. I did both of those things and was just going to live with the rough idle so long as it ran good otherwise. Spoiler alert: didn't work that way!
Sled would idle real rough but as soon as on the throttle smooth right out and run great. About 300 miles in i noticed a bog when i slowed down on the trail. Immediately went oh boy, here we go. It smoothed out after that and got my back to within house range. Stopped at a bar after a long run of 80+mph without a hiccup. Shut the sled off, went inside, came out a half hour later and went to start. Started on one cylinder, bogging terribly, backfired. Would only run on one. Got it back to the house like that, and guess what - NO PTO SPARK WHATSOEVER.
So i'm like cool, ignition coil and out. Installed my new ignition coil yesterday - still not an OUNCE of spark PTO side. Will still run on the mag cylinder. Compression 155-160 each hole.
I'll be honest, I now hate this sled. Electrical nightmare and at this point I'm not sure its worth the time or money to fix it. I'm not even sure it is fixable. Might replace the capacitor or something else easy, but other than that I'm at a complete loss. The new ECU fixed my problems for a couple hundred miles and now I'm back to square one.
Good thing I don't have much time to ride this year.
