Sick of skidoo junk good lord

[Big Jay]

Bought the rt 1000 didn't do my home work ,but when I finally got the engine running right every other peace of **** fuel stator wiring problem could go wrong did. Scraped that junk.

So went out bought a 2010 xp 800 154 with 1800 km on it. Got 3 rides and engine blew apart. Never should have sold my cat.

Unfortunately mileage means nothing. Either does brand when buying used. Know lots of people this happens to with all makes. Sorry about your luck though. You selling the xp with blown motor by chance?

 

[maxwell]

We'll the rt had had it's known issues. Too bad about the 2010 though they are getting some serious mileage. Previous owner probly didn't care for the engine too well that's really low km for a failure

Ya I've got 2250 miles on my 10, still all original pistons ect

Just repacked the pto bearing

sent while I should be drinking tea's

 

[sledneck_03]

I have not heard anything but issues about those pteks. Sorry doolades you can deny it all you want but alot go down.

Coming from a Polaris rider isn't that the pot calling the kettle black.

Yes cause im saying that the polaris 800 is flawless too. Dont get your pantys in a knot.

Polaris 800 sucked 08-10 bit better 11-12 better 13 and now better yet in 14 but still ****ty pistons.


There happy?

I was stating doo guys say thats a great engine and i hear about issues with it all the time.

So hows it better ,thats like saying are motors are better,but the rings still turn.

Empathize with the OP. Bought a 900 Polaris with out doing my homework and found out all about issues. Sled was stolen though so replaced it with a 07 Summit last year. Third ride this year and I am down for the year as the motor let go after 900 kms on a newly professionally rebuilt engine. Documentation to prove rebuild.

Why cannot the dealers build a quality/reliable 2 stroke in a snowmobile? Is it because of pushing the envelope to develop as much HP as they can out of the 2 cylinder engine? Our V6 1982 Johnson 150 HP 2 stroke outboard engine runs and performs today like it did 31 years ago. Plugs, timing check and gear oil and she is good to go. Burn cheap Canadian Tire engine oil in it as well versus the sled burning BRP branded oil. The engine has seen a ton of use and abuse. My 2008 50hp Merc outboard has seen more use than the Summit and it is still purring right along.

The lack of reliability in the engines on these snowmobiles is taking away any fun associated with the sport for a lot of folks. How does a family enjoy it when the dealers are making nothing but disposable sleds when it comes to the 2 stroke engines? Warranty is fine but still lost opportunities to enjoy your sled when it is in the shop getting a new motor.

My rant is not brand specific as Cat, Poo and Doo are all equally smelly with the 2 stroke reliability issues.

Lots of differences...we want big hp and very light weight. The current 2 stroke engines put out hp that rivals some indy car engines that are rebuilt every race. For the output we're getting and the rpm turned with in my mind minimal cooling...reliability isn't as bad as a guy thinks once we consider all the above.


boat motors aren't a good comparision. Motor displacement is larger per hp and turns at a lower rpm with a endless cooling supply.

Ya there's 10 million of them on the hill your going to hear issues. In general, if properly taken care of they are an extremely reliable, powerful motor. After 2007-2008 of course

I can sympathize with OP. When the Rotax 800 came in '01, I can remember a lot of people including myself with the infamous ring flaking issue and a lot of top ends being rebuilt. As a result upgrades to piston rings were implemented and it seemed to get better. Then the 800R in 2007 had a whole other bunch of problems with the case tolerances being too tight and crank bearings began to size up on everyone.
Prior to the Reed case engines being released, the 583 and 670 rotary valve engines were bullet proof and went forever. The point is every manufacture has flaws, but unfortunately, Ski-Doo has a lot of issues in the past decade that has led to a lot of recalls and shops full of sleds under repairs. I can understand for a person or family that is not mechanically inclined, this would be quite frustrating.
That being said, if you want to be active in motorsports of any kind, a person is going to have to learn the basics when it comes to engines and maintenance on these machines, otherwise you are going to be nickel and dimed to death. Like my Guido once told me.."if it has pistons or a pu$$y, is gonna give you trouble"

 

[slededjr]

I really don't understand how you only got 900 km out of a completely rebuilt motor from a reputable shop?? I've used brp, CV Tech, mongoose cranks, and mcb, spi, wossner pistons and never had an issue. So what parts are they using to only last that long? What was the failure?

 

[LUCKY 7]

I will never ever buy another cv tech engine ever...

[slededjr]

I heard a few say that as well, but I personally have never any issues with those guys since 99. Everybody has different luck and results though.

LOL so riding on snow is not an endless cooling supply? I would argue that point all day long, boats are no different, they simply have an open cooling system as opposed to a closed system but so long as the coolers in your sled have snow getting to them, the intake water at your cylinder can be as cold, or colder than what a boat motor sees in the lake all summer long.

There are many many many known street motors in cars built from aluminum. I don't see how building a lightweight motor means it is no longer reliable. The physical mass of the motor itself aside, any reduction in the rotating mass of the engine makes it more reliable as the rotational forces are reduced. Any harmonics in the rotating mass can be minimized by using a balancer. Light weight means faster revs. Indy cars turn revolutions about double what a sled does, and have way higher compressions and specs like 20K voltage ignition systems. Nothing like a 2 stroke motor IMO. If you spin your 2 stroke at 15,000 rpm you will be rebuilding it every ride as well.

reliability is terrible when you look at what sleds were getting 15 yrs ago. not uncommon to see a 1997 Polaris Indy with 10,000 miles on it in Ont.

For all manufacturers, we are seeing issues with reliability due to leaner oil/fuel ratios, direct injection (DI) and higher RPM demands. HP wars amongst the manufacturers mean lots of guys are running 8,000+ rpm on a 800 twin. 15 yrs ago the only thing that made it over 8,000 and lived were triples. I remember getting my first 670 and limiting it to 7700 rpm. With more RPM, comes more issues. Also, the motors are getting less oil due to emissions demands.

DI has had an impact on the bottom ends as the lube dimply doesn't go there anymore. Cat has been claiming great success with the new CTEC 2 motor that sprays the piston directly through the slot. I've heard of pistons with over 7,000 miles on them and the coating isn't even worn off the entire piston. Time will tell if their theory proves true.

My opinion is yes the engines have they fair share of troubles, but I also believe that a lot of failures are self inflicted.
not bringing engine to proper temp is huge, this goes for even after sitting at the cabin or bottom of a hill for half hr or less.
Non OEM oils and or poor quality gas, snow ingestion and intake fuel system freezing in -15 -20 -30 temps, stale fall fuels not cleaned out, condensation from improper storage practices, not watching for improper idle and rev symptoms caused by dirty carbs or air leaks, belt dust ingestion and so on. If it is a part that can be replaced then it is going to break, some sooner than others unfortunately

I agree.
Maintenance on these newer higher hp sleds is key.
I have a surveyor friend that has 4 2010 Tundra's. 2 ACE 600 and 2 550F. All have over 10 000km on them and never had the engines touched. All he does is drain the fuel to a min and fog them and they spend the summer in the barn. Lets them warm up good before he rides them everytime and no issues.

THATS still not uncommon, thats actually low. probly for all brands skidoo included. its a different style of riding. i guarantee there arent 800r motors failing at 1800km out east and i bet a good percentage of trail sleds will hit 10,000 no problem.

EXACTLY.

i cant beleive how many people fire there sleds up in the parking lot and immediatly fire it into reverse, back off the trailer, shut it off, gear up for ten minutes, then proceed down the trail at mach 1. crack a beer at the cabin, let sled cool down for 30 minutes. fire up sled and scream away from the cabin at mach 1 again. THOSE are the engines that fail.
even taking a 10-15 minute rest can cool your engine block down FAST. thats why i like the temperature guage feature. my sled doesnt move until 3 bars which means coolant is circulating.
