I currently have a 2008 mxz adrenaline 800r ptek. The motor is blown. I can get a good deal on a new used engine from a 2010 mxz. Will this motor work in my sled? I believe the 2008s and 2010s had different cranks... If this motor is not a direct fit, does anyone know what would need to be done...

I was doing some pre ride maintenance on my 08 Summit with the 800r PTEK and noticed my clutch had some movement up and down. Pulled it off and can move the crank up and down by hand. Obviously this seems bad. I'm assuming the bearings are shot. Sled will still start and run fine even did 20...

Hello , I have a big difference in my spark I need your advice for the grey spark , you can see on the photo , I already tried to turn out 1/4 the fuel screw for idle richer , Does I need to worrying about the grey spark ? Is it too lean ? My cylinder was washed for the rebuild could be small...

Bought a 2008 summit 800r with low compression for a good deal. Doing top end and would like to know what you guys think caused the piston to go. Checked out a few charts and can’t tell if it’s lack of lubrications or overheating. Would be nice to know to prevent new pistons and newly plated...

SHOULD I BUY IT??? Just went and looked at 2008 Ski-doo 800R MXZ Renegade. 3150 miles. Electric start. Reverse. New skis, new track -1.5 inch lug, 137 inch long track. It may not be what you want, but it IS what I have been looking for. Seat in great condition, everything cosmetically...

My 2012 summit 800 keeps popping reeds and can't figure out why runs really good but slightly pops on downrevs when your wide open and let off. I'm using spi reed replacements but still should be able to get more then 150 miles out of a set!! Where do I even start to figure out the downrev...

Hey people, I was wondering if a summit 800r ptek 2014 with less than 3000km worth 4200$ is a good first sled? I want to do some trail but also off trail. Sometimes I'll be riding two people on it also. My father keeps telling me to buy a 4 stroke because I'm no mechanic. There is also an...

Ok, so I'm getting all my sleds ready for this winter. Got an 2007 ski doo summit xrs 800 I checked the compression 90 psi and 95 psi. I ran the sled until it was up to operating temps and held the throttle at wide open during the test. I guess my question is should i go ahead and do a top...

Just wondering if anyone has the bike man performance 860 etec big bore.. I have a 13 rene 800r etec and was looking into big bore kits, I seen this one and it looked pretty good so I was wondering if anyone else has had this and can give me their input.. Thanks

I've seen a few posts from back in the day about this topic but none from recent time.. I have a 2013 renegade x 800r etec and I was looking to get some more power, I understand it is a trail sled and I though about upgrading but it's a little out of my budget so I'd rather just keep what I...

Hey , I know this topic has been beaten to death and I did doo a search for 800r in this section; read about 20 pages and most of them were referring to 800r swaps or 800HO cylinders for a 770 build. My question is will 2009 800R cylinders work for the 770 build or they have to be 800HO? I...

So I'm not sure if this has anything to do with my failure, but figured I'd run it by you guys to see what you think. I may be off base saying the bearing buddy failed, but what appears to have happened is the cap that plugs my fill hose came off and the hose puked some isoflex, and appears to...

Just bought this sled from a guy in Iowa. It ran perfect for the first 100 miles or so and on my last run back to the truck it started acting up. At WOT it sounds like it's down a cyl or the computer is preventing it from running full power for some reason. A few things I've read say could be...

I've spent hours going through posts to help troubleshoot my battery isn't charging. For the life of me I cannot locate the voltage regulator in this machine, even the parts view doesn't show one. Any help would be appreciated, bottom line is I'm trying to test stator output but ruling out all...

Hey all so I bought a new cluster gauge for my 09 renegade 800r... and now it doesn't seem to be working right... Old one was pretty beat up, and so it just needed a new one. So I bought it, but now the digital isn't working... It lights up after it starts up and seems like it should be, but...

Bought this sled in July been going over it since. Before I bought the sled I did a compression test. I bought my compression tester at Crapy Tire so I don't exactly trust it. The test read about 120psi each side (throttle closed), I don't remember the exact readings, but it was in that ball...

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...

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...

My 16' Renegade BCX 800R E-TEC is having issues getting into reverse. Regardless of engine temp, when pressing in RER, it just shuts the engine off and can't get it started in reverse again. Have no issues starting the engine again, but when pressing RER, it just dies off. Anyone know about...
