Good morning everyone,
I recently bought a 2012 Pro 600 w/ 155 track for my teenage daughters to ride. Outfitting the entire family with sleds without breaking the bank has proven to be difficult! ? Anyway, the sled had 2400 miles on it when bought but seemed to be in really good shape and I didn't notice any issues. I'd estimate we have put 50-75 miles on it this winter. At first she seemed to be running fine, but is suddenly fouling the exhaust side plug like nobody's business. Here are some thoughts and additional intel:
- This seems to be happening every 10 miles or so. It will get progressively worse and after stopping, I will need to baby the throttle to get it to start (while pulling on the starter cord). I shut the sled down for the weekend once it was obvious I had a problem but I still needed to get it back to the trailer.
- After initial research, I thought maybe it was because I didn't let it warm up enough (running rough, electronics flickering, etc.), but it seems to continue fouling plugs even when warm and on the trail.
- The plugs look dark grey/black - like they have excessive carbon buildup on them. I can post pics if it will help.
- I am currently running the non-ethanol resistor but AM running ethanol free 91 octane. I haven't switched because I wanted to ensure I had ran all of the "old" gas out of the tank prior to going to the ethanol free resistor. Could this be causing the problem? If I try the ethanol free resistor, what are the chances the fouled plugs go away?
- Does starting and stopping too much lead to a fouled plug problem? I've never had an issue like this with my other sleds, so my gut says no, but its worth asking.
- Other threads point to a TPS issue and I will check that out. Is there an easy way to do? I did find this video, and it's seems manageable but am wondering if there are any other tricks?
- I plan on inspecting everything tonight when I get time and am hopeful I find something obvious but am not counting on it. I've seen plug wires mentioned. Is there anything else I should be on the lookout for? Maybe a bad coil, something going on with the throttle body? Any tests I can run? Any and all help is truly appreciated.
- PS - this machine doesn't seem to be using much oil in my opinion. Like I've mentioned above, I estimate we've put 50-75 miles on the sled and my oil reservoir still seems almost full to me. Could lack of oil be contributing to this problem?
