  2. Skandic / Expedition
    Hi all. I am mostly writing this to document my saga with diagnosing a very rough idle and bad backfire I was experiencing with a used sled I purchased recently. It may help others having the same issues. I recently moved to a northern community on the Quebec side of the James Bay. Winter comes...
  3. MXZ / Legend / Summit / Grand Touring / Formula
    I recently purchased a used 2006 Ski Doo MXZ 550F. It has ~10,000 mi on it. According to the mechanic of the guy I bought it from it needs a new "reverse pickup coil" (his words) in order to go into reverse. Currently if you push the RER button it will slow down and then stop - It doesn't start...

  5. Skandic / Expedition
    So I'm working on a 1996 Rotax 377 in a Scandic. Ducati ignition system. So the engine abruptly died. No spark. Measured stator and trigger, all values were within spec. So ordered a new coil/CDI (SPI brand). Got a weak spark, now and then, so no success. Because the sled was outdoors when I...
  6. Skandic / Expedition
    I have a 2003 Skandic 500F, I primarily use it for grooming trails a few times a year. At the start of last year my battery went bad so I replaced it and it still would not start with the starter (pull started fine). I checked the starter and it did not seem to be getting power, so this week I...
  7. Skandic / Expedition
    Hello folks, first post here. I actually joined the forum for this issue despite reading it for years. This season, my Skandic has been giving me DESS issues. Not every time, but on 70% of starts, I get the steady beep and flashing DESS light. The machine may not move for sometimes 3 or 4...

    Hello Everyone I'm currently restoring a '78 MotoSki Sonic 340 F/A. At this point I don't think that I will restore it to 100% original. It will probably come in somewhere around 90- 95% or so as I've been looking for an exhaust can but having no luck. I plan on showing it a bit and riding it...

    Hello all, got a 1980 Mirage II with a 377. Previous owner said sled didn't run. Took the motor apart and nothing looked terrible, except the crank seals looked like they were done. Rebuilt the motor with new seals, pistons, condensers, plug wires. Compression is over 100, both sides...
  11. MXZ / Legend / Summit / Grand Touring / Formula
    I have two 1999 Touring E 380's that I bought new. One runs well but the other barely ran at the beginning of this season. I pulled the carbs, gave them a good soaking in carb solvent, and replaced the jets. The sled runs much better but it has a skip I can't chase down. I replaced the plugs and...
  12. MXZ / Legend / Summit / Grand Touring / Formula
    I just got a 2002 MXZ 800 that had been used as a water skipper all summer. It had been running great, all in needed was for the accessories such as headlights, dash, seat, etc. to be reinstalled. When I got it to my garage I tried to start it but it had no spark. So far I've checked all the...
  13. Elite
    I'm begining to study the wire diagram for my '04 Elite to figure out why the tach dosen't work and the temp light Flashes when it starts. Can someone tell me what is suposed to happen when you turn the key to "on"? Now all the lights come on, temp light flashes, and the Bat.light and Acc lights...
  14. REV-XP / XM Chassis - Mountain Sleds
    Anyone experienced this or have any suggestions? After 30-45 seconds wide open on hill climbs, my engine loses power quickly and dies. If I'm in a committed steep hill climb spot, it's scary. If I immediately turn back downhill, it recovers and runs fine until the next climb after being...
  15. Elite
    I'm going through my new to me 2004 elite, fixing all the things that need attention. Since wiring and electric circuits are not my forte, but know enough to be my own worst enemy. I've come to the forum hopefully to find someone who can point me in the right direction. My Elite starts, runs...

    So, my '70 Olympique 299 single is giving me more grief than normal. Here's the problem; from idle the engine backfires just before the clutch engages and won't rev up. Now here is the background; typically this machine runs well but will occasionally foul a plug, put a new one in and it would...

    I have an 07 Renegade X 600 SDI. I just recently(intermittently)experienced a problem where under heavy acceleration the engine would appear to stall for a brief moment and even make a popping noise. Also at times the electric start function would not work although it would start with no problem...

    Hey Guys, I'm new to the site and I hope someone can assist with an issue I have. I recently rebuilt an 86' Citation LSE and had her running like a charm last week, started with the key no problem, However, I did notice some issues with the headlight being very dim and figured I should get a...
