Hi, I'm totally new to this site...forgive me if this is not the right place to ask this. My son has a 2008 GTX 550F, the other day he lost the engine in it (piston and rings). I replaced the piston and rings and now the machine runs very rough and the entire engine is covered in oil. Anyone out...

Will a motor from a CK3 chassis bolt into an F-2000 chassis?

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...

will a 99 670 mount straight over onto a 2002 summit frame? Some background. I lost the motor on my 02 800 Summit Highmark. It lost all of the fluid and seized up while my son was riding it. I found a couple of engines close to home but one is from a 99 670 formula SS and another is from a 99...

Hey guys so here's whats going on. Recently I "siezed" the motor in my 600 SDI. As I started to dismantle the engine I noticed the nut on the cable adjuster on my oil pump had backed completely off, there's my answer to why it seized... Anyway, the engine is fully torn down and tragically my MAG...

My etec 800 from 2011 starts and works normal in every way, beside that every time I let go of the throttle and rev starts to sink and are supposed to stay at idle 1200rpm, It just passes that point just like the snowmobile doesn't have any idle. The result is that the engine dies every time i...

A friend of mine recently purchased a 2014 renegade 800 etec, and had an engine failure 40kms into his first ride on it. I've since torn the engine down and found a catastrophic failure in the PTO side cylinder. I'm having a hard time telling what may have caused the failure due to the condition...

This last year I noticed the tunnel cooler heating up right away when the engine was started from cold. Took longer for the engine to warm up. Evidently the thermostat is stuck open.... or is it something else? Coolant is full. (I have 2 900's, same sleds, and the other sled the engine warms up...

(UPDATE: IT seemed like the oil was darker than normal for only getting about 1400 easy trail miles on this past winter. Thermostat was stuck open which may contribute to oil getting darker quicker. See my thermostat post for more info.) What's your engine oil looking like at the end of the...

Picked up an 06 summit 800 151 in trade, figured it would put me back in about where I left off with my 05 roughly ten years ago. The sled has about 3600 km on it and from what I read the outside main bearings need isoflex about this time. Figured out pretty well how to repack the pto...

I have a 2007 mxzx 440 that has been going back and forth from running perfect to bogging at all times. I recently had a bogging issue and discovered it was only running rich. So, I raised the main needle to the highest position (it was on the 2 from the top) and after that it ran like a champ...

The oil light went on last week on my Expedition 600 ACE 2015. I changed the oil and found the old one to be very milky and liquid. Didin't think much of it at the time but a week later the same thing happened. I saw a couple of old posts here suggesting water or coolant could leak into the...

So, last weekend I went on a snowmobile trip up north about 4 hours away from where I live. First day was great! Sled ran and started up fine. Second day got ready to head out again started up my sled for a few minutes filled it up with premium gas mixed with amzoil at 33:1. Same mix, fuel, and...

Okay guys so I have a 2004 600 SDI and along with a possible gasket leak which I have another post going for...I was out last week on a run with the boys to diner and its about a 90km run round trip, about 3/4 the way back I couldn't rev over 6,500 and my engine light was on, when I got home I...

Hello folks, I have a 2004 600 sdi which I think is leaking at the base gasket, I'm not a hundred percent sure though, I'll degrease and clean it the next warm day we get and see. But the front of my motor from the bottom of the exhaust flanges down is coated in oil, is there any other seal it...

Hello All!! Time to start working on the sleds!! I have two 2005 500ss sleds that I've owned for a while now. Love them. Both ate their second sets of pistons at the end of last year (blew top ends on last trip of season). Each engine has around 14,000 miles on the crankshafts. Cranks are...

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...

I was riding last week and I noticed that I'm getting to 7600-7700 RPM instantly and after 5 seconds or so....pop 7900. I know the Rave is opening at 7000RPM...I can hear it plain as day with the can I use. After that it's hard to tell. I don't think it's clutching as I was routinely hitting...
