  1. REV-XP/XS Chassis: Renegades/Freeride/Backcountry
    So I’ve got a 2008 XP with a motor that is not salvageable. I was wondering if I could buy a ZX/REV 593 block (600) (NON HO) motor and buy a bottom crankcase half for a 2008+ and put it in place of the one that’s on there to make it work with the motor mounts? Or would that not work? Thanks for...

    So I have a 2004 Summit 800 HO 144 that’s not in the best shape. The motor itself is great, starts right up and runs the way it should. Only problem is that the rest of the sled is pretty bad, especially the track. Almost all the lugs are ripped and torn, and the thing gets stuck constantly in...

    I have a 2004 500ss. Already bought x package piggy backs for the front. Now I’m looking for a set for the rear. Was told by someone that sc4 piggy backs would work with a certain bushing from hygear, but I called them and they had no clue what the guy was talking about. I’m not trying to call...

    I have a 1998 Grand Touring 500 liquid cooled and would appreciate knowing what track lug size will fit in the tunnel, trying to replace the track now, was told a 1-1/2" lug track would swap in no problem. Have searched for info and found different stories on different similar machines - some...

  7. Vintage Ski Doo's
    Hello Everyone I'm currently restoring a '78 MotoSki Sonic 340 F/A. At this point I don't think that I will restore it to 100% original. It will probably come in somewhere around 90- 95% or so as I've been looking for an exhaust can but having no luck. I plan on showing it a bit and riding it...
  8. REV-XP/XS Chassis: Perf. Trail 120-129 Inch Models
    Hey guys I recently purchased a 2012 xrs 800 etec and I seem to have bent the rails. I'm having issues sourcing a set of used 120" r motion rails, but I've lined up a full skid from a 600rs from the same year for cheaper than a new set of rails. I plan on using the sled for freestyle and had...
  9. Vintage Ski Doo's
    I have a 1979 skidoo citation 300 that has the standard 114 x 15 track and I was thinking about swapping the skid out so I could run a little bit longer more common size track, like maybe a 121 x 15. The reason I want to do this is because the only 114 tracks I can find have 0.5" lugs but that...
  10. REV-XP/XS Chassis: Perf. Trail 120-129 Inch Models
    Hey guys, I've been pretty disappointed that Ski doo hasn't brought back the Mach Z since 2007. And I have a feeling they won't for some time. So I've gotten the idea to make my own by putting a 1000 sdi into my 2015 mxz xrs 800. The sheer power potential from that motor has my mouth watering...

  12. MXZ / Legend / Summit / Grand Touring / Formula
    Hey guys, New to forum, but not snowmobiling or working on them. Bought a low mileage 2000 Formula Z 600 with a burnt out piston. Come to find out the right side cylinder head is scored pretty nicely. Looking to find one in the used realm, but need to know what years and models they used the...

    I have a 1990 617 mach 1 otherwise known as the mach ton. I rode it this year and decided I hate the chassis. I just bought a 1998 670 chassis and plan on dropping my motor into it. Does anyone have any advice or will this even work? Also my motor runs great once you get it started... once I...

    Has any one ever taken a xp race sled and swapped the stock 600 out for a 800 etec?
  15. Vintage Ski Doo's
    Hey everyone, brand new to this site and hoping to get some great advice. I have some questions regarding a motor swap that I'm planning to do on a 1991 Skidoo Safari. I'm swapping the 377 out for a 503 that came out of a 1980 Everest. The 503 is a single carburetor model and I'm wondering if I...

    I have a mxz x 600ho sdi. The original battery is small in size and 12v 14ah, inserted in some kind of foam inside the "batterycase". Have installed some extra accessories on my sled like led lighting etc. Now i'm looking to install a larger battery, like 12v 20-21ah. Can i do this or will this...
  17. MXZX Race Sleds
    Uploaded some pics of my 2008 600 RS motor in my 2007 REV 600 mod sled. I'm now running all 600 mod electronics, flashed for trail curve, and TMX 38's. I've been playing around with different pipes, right now I'm running a 600 HO single pipe with dynoport can. I did try my 600 MOD twins and...

    I have a 2007 summit with a destroyed 800R: http://www.dootalk.com/forums/topic/760418-which-bottom-end-fits-the-p-tek I also recently picked up a 2004 Rev MXZ with a 600HO that has buggered up front end. Nun, A-Arm, and the front brace are bent or broken plus maybe more. The 600 has an MPEM...
  19. MXZX Race Sleds
    I got a 2007 MXZX 600 factory sled that was trail converted (HO head, ECM reflashed, single pipe, etc). The sled was blown up when I got it and I just got a 2008 600 RS trail converted motor for it. What all will I need to do for this swap? The cooling lines are different and I'm not sure how...
  20. MXZ / Legend / Summit / Grand Touring / Formula
    I am in the process of converting my stock 99 MXZ670HO to a 136 track with what I believe to be a SC 4 suspension. My original suspension (SC 10 I believe) is getting old and tired and now needs new bearings and more, but I would rather put my time and money into getting this suspension in then...
