    So I picked up a beat up 440, it sat a long time in the shop while I piled parts to fix it. Finally I got it going. From what I’ve been told it was a ripper, always put gas n go. But I’m finding it was running pretty crappy in the -7c the other day. Takes off after sitting for a bit..but 2 mins...

    I bought a 9500 Blizzard back in the 90's parted it out back then but kept the engine. I was going to use it in a project, never did. I think it was out of 79 or 80. I thought the only difference between the engines were the ignition system. Thanks for any help!

    So I’m trail converting my 2006 mxzx 440 and I had the head sent off to get it machined to low compression. They need to know piston deck height and piston crown rise. Any help would be appreciated thanks

    Hey guys. So ever since I bought my 72 Nordic I have been trying to decide what to do with it. A resto is impractical, as it needs a track, which are no longer produced (18x114), the seat is junk, the fuel tank is cracked pretty bad, all the chrome is rough, and the tunnel is pretty rusty...

    I have an 07 mxzx 440 that I am switching the engine out for an 800. The engine is off of a 2003 mxz and I know that the engine is not the only part that is necessary to do the swap. I know the computer, and voltage regulator also are necessary components. I am just wondering if anything else is...

    I"m talking to a guy that has a tnt Everest 440 and a tnt 440 for sale. Both are fan cooled. I haven't seen either of them in person yet. What is the deference between the two? I believe they are both 1974. I'm leaning toward the Everest, seems like it maybe a little more rare. Thanks for any...
  8. MXZX Race Sleds
    I have a 2007 mxzx 440 that has been going back and forth from running perfect to bogging at all times. I recently had a bogging issue and discovered it was only running rich. So, I raised the main needle to the highest position (it was on the 2 from the top) and after that it ran like a champ...

    Hi, I have a 74 T’NT 440 free air. I know there weren’t a pile of them built, but wondering if anyone might know the production numbers on them. I have #936
  10. MXZX Race Sleds
    So, last weekend I went on a snowmobile trip up north about 4 hours away from where I live. First day was great! Sled ran and started up fine. Second day got ready to head out again started up my sled for a few minutes filled it up with premium gas mixed with amzoil at 33:1. Same mix, fuel, and...
  11. MXZX Race Sleds
    Hello gentleman, I have a question on what my sled would be worth. Last year I picked up a 2004 MXZX 440 with a 800ho swap. Very nicely done. It was a older mans "local" riding sled. The sled has 2500 miles on it. I am thinking about getting rid of it and wondered your opinions on its worth...
  12. MXZX Race Sleds
    The engine light on my 07 mxz x is blinking for some reason. I have no Idea why because my sled, as far as I can tell, is running and starting up fine. It blinks at a rate of about once per second. I`m thinking it could be a wiring issue on a sensor or something because of the fact hat nothing...

    My Grandpa has this 78 Blizzard 440. He is looking at the possibility of selling it, So I decided to come on here and see if anyone could give a valuation of what this might bring. It's an awesome sled!

    Hello everyone, new to the forum. Just wondering what it would take to put a modern track on a old sled with bogie suspension. I have a 71 olympique and the track is about as usefull as flip flops on a ice rink, and want to put a track on it with like 1 inch lugs or somewhere around that. The...
  16. REV-XP/XS Chassis: Perf. Trail 120-129 Inch Models
    The other day while ridding on the trail my 2004 MXZ X 440 snow cross ran out of fuel and needed to be towed to the station. When we tried to remove the belt we realized we did not have the correct tool to loosen the secondary in order to remove the belt. There were 7 Skidoo's there and we tried...
  17. MXZX Race Sleds
    I just got my first sled. Its kind of a Frankenstein. Its a 2001 MXZ X 400 upgraded with a 2000 600 motor. I have always wanted a sled but normally a bit out of my price range but i got a extremely good deal on this sled as the pulse line wasn't getting any vacuum. I fixed that easy enough...

    I'm looking for a new exhaust boot. Does any one have a part number, or know which ones will fit it? Thanks, Matt

    Hey hey. Picked up a 1977 Ski-Doo Everest 440/E F/C last year and finally got around to getting this thing running. No spark on mag side. Previous owner was kind of a hack, so I have a bit of mess to fix up. Purchase points, condensers, external coil(one wasn't reading any ohms), battery and I...
  20. REV Chassis - Performance and Trail Models
    Friend of mine is buying a 2004 MXZ that has a 440 trail converted motor in it. Its not the race chassis sled. What are some good modifications to do to it? Want to make it responsive but yet good offtrail. Thinking in the are of swapping gears around and reeds. But maybe someone else knows how...
