    Hi. Im fairly new to snowmobiles, and brand new to Arctic chat so I'm not entirely sure if this is the right place to post this, but I cant figure out what's wrong with it. I've tried adjusting the jetting, air screw, idle screw, and it still doesn't run right. I thought about adjusting which...

    Question: What is the height of a 580 cylinder? (From gasket to gasket mounting surfaces) As a follow-up, does anyone have an engineering dwg of the stock pistons? I have the bore and stroke dimensions, but I have no clue if the stroke is from the cylinder base or top of the intake ports I'm...

    I recently bought a 98 Pantera that the lights and handwarmers don't work on. When I dug into the voltage regulator/rectifier, it appeared that someone had previously replaced the regulator. It is a 5 wire regulator (black, red, and 3 yellow/red). The previous repair clipped the connector and...

    Hey Ya'll, I've got a 1995 ZR 580 EFI that I got for 500 from a friend. It runs but it's a ditch banger and it has its issues. The main problem with it is that the engine is limiting itself to 5000 RPM sometimes. It can be immediately upon starting or happen after anywhere from 5-10 min of...

    I went for a ride last night and after about 20 minutes it started to get kind of 'numb' if I was just riding at a steady speed, but if I gave it some more fuel it would come right back. As the ride went on it would get number and number and would stop coming back. I would have to let it idle...

Sorry for the book, just don't want...

    Hey guys. I got a 94 zr 580 carb. And I keep hearing a sort of ticking noise near the primary clutch (comet 6 tower) and the ticking goes faster as the clutch turns faster. I'm kinda worried I might need it to be rebuilt. Any suggestions on what it could really be? Thanks
