  1. REV Chassis - Mountain Sleds
    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...

    Well, new 2020 with no miles, bit of white stuff and thought Id break in the sled. 850 XRS, filled with fuel and realized a bad leak was at the O-ring that seals in the fuel pump (FUEL HAS NEVER BEEN HIGH ENOUGTH TO SEE THIS UNTIL NOW) , I don't think it was ever in correct. I have tried too...

  5. REV-XR/XS Chassis: 4-TEC 1200 Perf. & Trail Models
    I just purchased a 2010 MXZ 1200 Adrenaline with 500 miles on it and after riding about 25 miles, there is a sputtering and loss of throttle. It will maintain speed but it will not accelerate. Every time it happened I was light on the throttle riding over bumps (not sure if that is a trigger...
  6. REV-GEN 4 - Summit/Freeride/ 850 Turbo
    Hey guys, Sorry if there is an existing topic on this, I tried to search on it and found nothing. On a 2019 Summit X, I ran low, low, low on fuel. Beeping and flashing for a while but still going. I noticed my bar warmers stop working, it wasn't cold out but the bars quickly became ICE cold...
  7. Freestyle / Legend / Tundra / Expedition Sport
    I have a 2012 Expedition Sport 600ace. I have been experiencing an intermittent problem with it cutting out suddenly ( as if engine shut-off was depressed) and then not starting, or not starting at all after having been left. The engine will turn over but not fire up. The fuel pump, which you...
  8. REV Chassis - Performance and Trail Models
    My 2004 ski Doo gsx sdi (fuel injection) model has a fuel problem. Just went through the entire sled all is set. But once the fuel tank gets to or below 1/2 tank it will stall and spitter at high rpms. Idles perfect still. Put a fuel gauge on it, rode it, and the pressure drops. I took the pump...
  9. Mountain Riding
    I haven't seen anything on here about running racing gas or high octane fuel through etecs. Can you run it when with a stock engine or do you need upgrades? Has anyone tried this?
  10. MXZX Race Sleds
    Hello everyone, Quick question. I have a 2008 600rs and it starts and idles great. Sled runs good and pulls hard until i try to hold it wide open. 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...
  11. Freestyle / Legend / Tundra / Expedition Sport
    Hello everyone. I was curious if anyone knew whether the a replacement gas tank for the 1996 Tundra II will fit on a 1993 Tundra II. I just bought my sled and the gas tank neck snapped off. Was going to glue it on, but it got mangled getting the broken piece out of the cap. Now I need a another...

  13. Mach Z RT and MXZ 1000 SDI Models
    Long story short, last season my 2005 Mach Z 1000 sdi ran great. My last run was late March (I live in MN). I just put a new skid in and went to fire her up so I could get my track aligned and to my surprise she wouldn’t start. Battery was still fully charged, plugs spark great, and the pump...
  14. REV-XP / XM Chassis - Mountain Sleds
    Hi! I bought a complete, but used, Straightline Performance (SPI) 860 e-tec big bore kit for a 2014 Freeride. Ive installed it but I'm now having issues with the fuel controller. It seems like the settings doesnt get saved when I restart the sled. I enter the changes and let it go back to the...

  16. MXZ / Legend / Summit / Grand Touring / Formula
    I recently went on vacation for a few weeks and when I got home I tried to start my 01 mxz 600. I pulled it over about 10 times without it firing so I took the plugs out and they were wet with oil but I didn't smell any gas. I took the exhaust off about a month ago and the expansion chamber had...
  17. Sledding - General Discussion
    There seems to be a lot of controversy over whether Octane Boosters really do work or are they just snake oil? Some say they work, while others say they do not, which is it?

    Hi, i been having problems with my sled all season, its done about 4000 km and ive been loosing rpms all this year and im going crazy, it revs out without any heavy load such as trail riding but not in deep snow, it goes down to 6900/7300 and jumps up and down.

  19. 900 ACE 4-Stroke Models
    Was not a fan of the linq system as I wanted to keep my tunnel bag so I came up with this. Purchased a rack from Up North Technologies, 1 gallon Rotopax fuel can along with mount and an extra set of buttons so I can move the tunnel bag when I am not carrying the fuel can. I purchased a 5"...
  20. REV-XP / XM Chassis - Mountain Sleds
    I inherited a wrecked 2009 Rev XP 800 Summit Everest P-Tek. The E and S modules were replaced, but when the sled was more or less back together no fuel was making it to the carbs. I pulled the tank off and siphoned gas out of the outlet port. Fuel came out as expected, so I am not thinking it is...
