  1. REV-XP/XS Chassis: Perf. Trail 120-129 Inch Models
    Here’s a pic from some field riding (landowner approved) we did last year. It’s across from our home, so the dogs like to run behind the sleds and I couldn’t resist a pic. We have two of these 2015 MXZ carb models and they’ve been incredible. Roughly 6000 miles on each and zero issues thus far.

  3. Vintage Ski Doo's
    Hey I have a 250cc single elan and it runs like brand new, does not bog, and sounds aweosme. But if it doesn’t start first pull then it doesn’t start. I have read that this is the float sticking or a problem with the needle valve. Am wondering if this will work as a replacement carb or if anyone...

    2002 mxz 800 Little backfire on deceleration. Sleds runs great otherwise. So Put on 65 miles today, half way through my ride I noticed as I slowed and let off throttle from 4k + rpms I’d sometimes get a random backfire, just a little pop out of the exhaust. Also noticed the sled is really bad on...

    Swapped the 250 twin for a single in my 78 elan dlx, reused the carb from the twin (hr-172a) it starts easy and idles smooth, but it wont rev past 1/3 throttle. It's just enough for it to move but noe more. Plug is black and wet so it seems like the motor is flooding. My first thought was that...

    Hey all, new to the forum here; thanks for any help you can offer ahead of time!! I’m having a strange issue with my Rotax 800. The issue is that it wants to continue to pull and keep going for a second or so AFTER letting go of the throttle. It seems to idle ok (now: see below) but not...

    Hey guys, for starters I'm sorry about the long post, just want to include as much info as I can. I have a 95 MX 470 I picked up, hasn't been running since a couple years & I haven't had it running right yet. When I pulled it home I got it running to find it was only running on 1 cylinder...

    I bought a 1985 safari 447 the guy gave me a carb that he said would work for it. But after looking up the info on it, it will not work plus the carb is trashed. The manual says it should be a Mikuni VM34-310. I can not find that carb anywhere and the closest I can find is VM34-275. Can I use...

    I have a carbed 860 in an xm chassis and am looking for a little more. I recently picked up a bondi air box dirt cheap to play around with next winter.

    I have an '81 Everest 503 with a single Mikuni carb that won't stay idling, it dies after about 10 seconds if I don't give it a partial primer pump or put my fingers over the carb throat. Dies from being too lean. Holding palm over carb throat or giving it a pump of the primer it starts right...

    I've got an 03 Rev 600HO that I had removed the engine to replace the crank seals (one popped out) Well anyway, I got it together and if I start it without the airbox on it runs and idles great but once I put the air box on it will start hard and when it does its like running on one cylinder and...

If i do a WOT pull it will pull approx 8100-8300RPM everytime and pull hard non stop until after 3-5 seconds of holding it it will then drop down to...
  16. REV-XP / XM Chassis - Mountain Sleds
    Been having issues with my sled... First the check engine light and overheating light came up on my dash. Shortly after the lights came on, the speedometer sensor gave out and wasn't getting any readings of the sled speed. Then shortly after that the reverse has burnt out. Looking for more info...

    Gentleman, I've finished cleaning and setting up my carbs to factory settings, replaced all fuel lines and tank filters. Cleaned and inspected fuel pump - seems to be okay. Sled starts cold (full choke) two pulls every time and will sit and idle for hours if I leave it. The minute I try to...

    I've got a 2001 Grand Touring 500F - Bought it at an auction for 400$ and it had been sitting in a barn for over four years. I've got nearly everything in the fuel system replaced/cleaned including the carbs - I just can't seem to find the settings for these carbs anywhere online and my...

    Hey guys, I have a 2013 Skidoo Summit Sport 600, 10300km and while I was taking my carb apart this is how my reeds were looking like (first picture clutch side, second is chaincase side). Last year my sled would start bogging if only I would crack the throttle from nothing to full throttle for...

    Hey guys, I have a 2013 Summit Sport 600, just reached 10,000km last year, I just want some input on what I should expect or what do with that kind of mileage. Last year I switched the sliders, skis, had brought it to the dealer to have a maintenance check-up (never doing that again) since I...
