    2009 MXZ TNT 600 ETEC Original issue was sled shut off during riding and could not get it to start, took it into the dealership and a few weeks of them not knowing what was wrong they call me and tell me it was just the spark plug wires were bad and grounding out. So I picked up the sled and...
  3. REV-XP/XS Chassis: Renegades/Freeride/Backcountry
    My etec 800 from 2011 starts and works normal in every way, beside that every time I let go of the throttle and rev starts to sink and are supposed to stay at idle 1200rpm, It just passes that point just like the snowmobile doesn't have any idle. The result is that the engine dies every time i...

    I have a mint condition 1970 TNT 400(399) that someone gave me to get her ready for the winter, My only problem so far is the track turns when it idles to the point that if I apply brake she will stale. Put a new Belt that is for this sled, loosen the belt between pulleys. Still have the...

    I've been chasing a single cylinder idling problem on my 2003 Skandic SUV for several weeks now. Everything ! has been torn down, cleaned and subsequently swapped to the other side and still the problem persists on the mag side cylinder. I gave it one last tear down tonight to try and find my...

    Hey Guys, I am stumped on this one and am looking for some help. I almost have this sled running well but am running into issues with it idling.

    2004 MXZ 600 HO SDI - Here's where I'm at..... Hoping someone can help me out here. Last week I went riding all day with no issue. Stopped for a bit when we got back, and when I started up again, I fouled a plug. Changed both plugs out with new ones (NGK BR9ECS) and she started up again. Ran...

  13. MXZ / Legend / Summit / Grand Touring / Formula
    Hi i have been wandering the forums for a few weeks, just finishing my top end rebuild trying to get all the bugs out before i put my sled away for the summer. Which is depressing to do. Before the rebuild the compression in each cylinder was 98 psi on both. The Valves were awfully dirty and in...

  17. MXZ / Legend / Summit / Grand Touring / Formula
    Just finished top end rebuild, started right up, sounds great and breakin is going well. I am having a high idle issue, where it idles around 3000 rpm. I did add throttle extension so I think it might have to do with the throttle cable and carb set-up. Any insight would be helpful.
  18. MXZX Race Sleds
    Hi guys, I've searched a TON on this but can't find anything that meets my specific issue. I recently purchased an 03 mxzx 440, it will start up on one pull and 3-4 primes, and idle at 2000 rpm until warm and fall to 1800 rpm. Which seems normal to me. But my problem is, when I touch my gas, the...
  19. Skandic / Expedition
    Hey everybody I have a 2014 skandic 600 ace that won't idle right. The problem is at idle the rpm drops and won't stay steady. It's runs and idles fine but then drops all of a sudden, some times so hard that it stalls out. This also happens when I'm driving and I let off the throttle to hard...
  20. REV Chassis - Performance and Trail Models
    I got this sled used just about a week ago, and it drives fine, starts in about 5 ish pulls. The gas has been sitting since march, but did have fuel stabilizer. When I start it up, it will idle decently with the choke, but when I flip it off, it goes to about 1000-1200 rpms, and will shut off if...
