  1. REV-XP/XS Chassis: Renegades/Freeride/Backcountry
    Was out riding this past weekend when my '13 Backcountry 800 which had a CV tech short block installed about 14 months ago, lost power instantaneously and threw a knock code. I've been down this road before so I pulled the spark plug to find it bent out of shape severely. We towed it home and...
  2. REV-GEN 4 & 5- Summit/Freeride/ 850 Turbo
    Uhh... 2018 850 etec with 3k locked up. 20 miles and 2 hrs into trip, water temp was 105F. Stopped for 30 seconds, started it and took off at a 15 mph clip. 20 feet later it beeped and flashed "rev limit" then immediate power loss and I slapped the killswitch. Locked up with maybe 10° rock...

    As most of us know the detination and/or seize of the 2004 800 H.O motor is nothing new. I haven't yet torn into it, but as it refuses to turn over at all, clearly some rod or ring or chip of something has granaded the motor. What confuses me: I went to start it in preparation for winter. It...
  4. MXZ / Legend / Summit / Grand Touring / Formula
    Fixing a motor I didn't blow up - where do I start? So I got a used sled for cheap with a brand new track, rebuilt clutch and a bad motor.

  6. REV Chassis - Mountain Sleds
    Picked up a Rev 800 for what I thought was a good price, but a couple of hours into day 1... The seller said his buddy worked at a doo dealership and put a new top end in 600 miles ago, 4600 total on the sled. I bought it with every intention of rebuilding the top and bottom (nervous about...

  10. Mach Z / Mach 1 / Formula III Triples
    I blew the track out of my 89 Mach 1 the other day and I'm looking into replacing it. What I can't find anywhere is how deep the tread can be without rubbing on the radiator fins down there in the tunnel. With my old track if I accelerated hard then the track would smack and clatter over the...
  11. REV-XP/XS Chassis: Perf. Trail 120-129 Inch Models

    New to the board so hello everyone! Having issues again with my sons 07 blizzard 800 ptek. Rebuilt last year with new cylinders, head and top end due to detonation. He had used low octane fuel is the only thing we could come up and it went boom not long down the trail. He has since put on...

    Well I thought I had my problem solved, but no!!! My 2007 600sdi Blizz keeps blowing Fuse F4, I recently replaced Rely R2 and fuse F4 did not blow for the first 5 minutes of easy riding. Then it blew again. It blows with the bar warmers and thumb warmers turned off, it blows with the helmet...

  15. REV Chassis - Performance and Trail Models
    So I blew my 07 800Ptek up last ride of the year. Just getting around to rebuilding it now. I figured I melted down a piston. I took the head and juggs off found I melted down the Mag side piston pretty bad. When I took the jug off I notice the entire Mag side of the bottom end was full of oil...

    Hello dootalkers. So I caught my kimpex piston's ring leaking carbon in one spot after breaking the pin that holds the ring. I am very peed off with this kit, and am not going to go with another. There are a few VERY small scrapes on the wall, but There is no way I'm paying another 1300 dollars...
  17. Vintage Ski Doo's
    So I finally got ahold of a compression tester, and my 447 tested 121 PSI Mag, 28PSI PTO on average for both. I did 3 tests each. What are the acceptable compression levels for this motor? I am hoping to get away with rebuilding just the one side, assuming the other is ok, but I think 121 is way...
