Polaris 800 CFI snowmobile engines simply don't use enough oil which causes premature failure. My Polaris Switchback 800 ran strong but had multiple issues. The 800 RMK engine was tore into just in time also.

I remember when there were two engine wires and one tube, a belt and 4 bolts to get the engine out. Of course I remember when a 16 HP Scorpion was a hot machine. I can't believe how complex these machines are now. You know what? Back in the day those machines were just as much fun.

yes but also back in the day, you could go slow and brake ffresh trail though 6 feet of snow, now you need a groomed trail or they just sink like a 1200 pond rock, but will go 100mph, oh ya so much fun,, not...

I love snowmobiling I always owned a sled. Up until the middle to late ninetys. My last sled was the 97 Polaris 700 Triple. Fastest sled I ever had. So This one late fall I figured I would take my sled to the polaris dealer that sold this sled to the original owner so knew the sled. I would take and get carbs cleaned and adjusted. They put bigger Jets in the sled when it was new., Badass clutch, and 144 spikes in track, and Pipes. Well needless to say they put the jets in wrong Carbs and Gave it back and my first ride it let loose. No sorry Or repair. Hell at the end of fighting with them I would of been happy with a Fuck You to me. But NOTHING... So I quit riding plus we didnt get snow like we used to anyhow. You brought back alot of good memories and one bad...LOL...Those 800 are Rockets ..Great Video.. I bet that long track is a hell of a trail breaker .. Sweet Sleds Bud ..

Brings back memories from last fall when I had to go through my 600 Rush at 8400 miles. A piece of something got in the PTO cylinder transfer port and ripped the whole side apart. New pistons, cylinder refurbish by US Chrome, seals and a used set of cases from ebay. I also sent the injectors out to be tested. They were all a little low but the were cleaned and brought up to spec. I changed my first set of pistons at 5500 miles due to the ring grooves getting wider. At 7000 miles I changed the jackshaft bearings and kinked my oil line from the tank to the pump. It locked up within 2 miles which caused me to put in my 3 set of pistons. I am on set 4 now and bought a 4-stroke for my main ride. The Rush is now the back up sled. My 2003 600 XCSP has 9400 miles on it and has never been apart!!!

Nice video, I tore into my sled season before last had to replace a crank bearing and replaced the pistons at that time as well. gotta tear into it again and just ran across this video. runs strong but getting water blowing out into the engine bay intermittently and can't quite determine where it's coming from. Suspecting either a bad head gasket o ring, or a mechanical seal issue. Hoping I get it back together before the snow starts falling!

Should a person try this, I suggest that the "Barley Sandwiches" be left at the home base a good ten miles away as it encourages a man to abuse this food substance to the limits. I put heads on a 429 ford truck engine out in the snow bank and it wasn't this complicated. I haven't drank for nearly twenty five years and this could cause me to severely test my sobriety for absolute positively serious overdosing. That would have my nails gone and the knuckles on both of my nose pickers in serious troubles. Wow, I did play with a few that had a half a dozen bolts holding it together. I took a snowmachine engine in to the machine shop and seen the amount of my engines in for catastrophically messed up machines and instead asked him if I had any parts he needed to put some of his down and dirty ones back on the trails... he offered me a hundred dollars and I took it. Best deal ever as I was too poor to own one
@CJE2007.53 жыл бұрын
On my no fuel injected sleds i always put a oz of oil in with a full tank of fuel just for that reason. Polaris had a pretty long run of not getting enough oil. Tip for anyone who is looking to buy a used sled pop the exhaust off and look at the piston skirts especially if in the description it say's "Fresh rebuild" unfortunately there are a lot of dishonest people out there these day's and you can have just as much $ wrapped up rebuilding engines in sleds like these as it cost to rebuilding a small block chevy. The 4 strokes are even worse especially if they have any power adders such as a turbo or nitrous or both. In my opinion snowmobiles these days have taken the crown from boats on cost to repair. "Break out another thousand" is definitely a true statement for both. I rebuild a lot of toys and nothing tugs on the heart strings more than when you get a guy who busted his butt to buy a nice used sled only to ride it a couple times and then it blows up. Just like my rigs i won't go any newer than a 07 with anything because of the electronics and the cost of repairs and even 07 has to much junk on them. Thanks for the video Dave it was nice to watch someone else turn wrenches on them. Feel bad for your pocket book though.
