  1. REV-XP / XM Chassis - Mountain Sleds
    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 am running the skinz helium hood with their intake shelf and was thinking of running a 3.5" tube from the bondi box to the intake shelf with a...
  2. Sledding - General Discussion
    Was just finishing my engine assembly on my 860 rebuild, and something I never really noticed before. The head sits over the coolant jacket seal, but basically stops there, lol. Can't really see it causing any issues? But just thought it was really weird. Must have always been like this, just...
  3. 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...
  4. REV-XP/XS Chassis: Renegades/Freeride/Backcountry
    Looking at getting my engine completely rebuilt in my 800r Ptek over the off season. Just can't decide which route to take. The sled definitely should have the crank rebuilt as the sled has 12300 miles on the stock bottom end. I rebuilt the top end about 3000 miles ago, didn't blow just did it...
  5. REV-XP / XM Chassis - Mountain Sleds
    Got this mono block from US Chrome last year bored to an 860. Had an engine builder do the porting, cut the head, and set me up with pistons, it runs good, but I noticed this on the mag side. Looks like it was damaged and attempted to be repaired but now it leaks a little coolant, if you look...
  6. REV-XP / XM Chassis - Mountain Sleds
    I know most of you are going to say to talk to the engine builder, but I want to know what you guys are running. Right now I have 200-320 spring with 433 ramps and 21g, secondary is team tied with purple spring and 66/62 helix. Looking for a little more bottom end pull, everywhere else seems to...
  7. REV-XP / XM Chassis - Mountain Sleds
    Hey guys, I'm in the process of building my first 860r. Just wondering if anyone has experience with running a timbersled intake with an 860 kit and where a good place would be to start with jetting, and also what base gasket to run. With my trygstad ported setup I was at .020 shim and 540 main...

We do a bit of trail riding, with a decent amount of boondocking. Just wondering what heads make the best hp with BJ's...

  19. REV Chassis - Mountain Sleds
    Curious as to peoples thoughts on ceramic coating vs just using ceramic pipe wrap? Im putting a set of factory race pipes on my 07 860r this year and figured if I can keep the heat in them it should be easier to tune...I hope anyways. Also has anyone ran these on just a stock 800r? Wondering if...
