    Hello I am new to snowmobile ownership and was hoping someone could possibly point me in the right direction. I recently bought a 95 Ski-doo MX 470. The sled won’t rev over 6k rpms with the track off the ground or under load. Download the service manual and 7200 is top rpm. Tops out about 40 mph...

    Hey guys, first time posting! My 2004 Ski Doo Summit HO has no spark and I am trying to diagnose the issue. I am using my multimeter to test resistance on the stator and I am not sure what readings I need. The plug going to my volt regulator with 3 wires (2 yellow 1 green) reads 1.5 ohms...

    Hey guy, I have a 1971 Ski Doo T'NT 399 and am curious about how the fuel lines work with the tilloston carb. There are 2 fuel lines from the tank directly to the carb. One goes into the side and feeds it and the other is on the bottom of the filter. Is this correct? Is there a pulse line? I...

I have cleaned the tank, and checked all of the lines, put a bit of oil in each head, replaced the plugs...

    Recently I've been having motor issues with one of our sleds and have a friend coming North later this month and need a quick fix. We've reconstructed the engine multiple times and drained the oil without any sign of getting better. It's our only two-person sled and my parents are looking to...

    What's up guys? I'm new to the page. I'm looking to add an ice fishing sled to my collection that still has some speed and would make a good backup or loaner sled for buddies to use when we go out on the trails. I'm looking at 2 different sleds and would like your opinions on both. First, there...

    I work for a very small ski hill and am a diesel mechanic by trade, so I'm not great with small engines. I primarily don't operate the sleds, so getting told what happened when things occur is slim at best. This started last week when the sled fouled a set of plugs out on the trail. The...
