Five motors on one 07 800R, there has to be something more wrong here.

I know of one XRS that is now on it's 4th motor and it's the 2nd owner. It seemed to run OK last weekend for him though (maybe he got a good one) Also know another guy that is on #3 motor and pretty sure it was OK for 2 days so far. Both are '07 800R's and pretty sure all the problems were cranks. Not a skidoo fan myself, just glad the guys had warranty.
 
cant comment on your described problem but know one well personnelly.each engine lost was bottom end , top end perfect .last motor they gave out is an 08 they stated . difference being the larger clearanced bearings i was told , but no thermostae provided as the 08's have one .humm.
this is number 4 and the previous.
first one had 300km's ,
second one 1600kms and
third had 2400 kms .
new one 400kms and definetly a peppier motor right from the beginning.
same dealer and the service was excellent .
he knew what it was and refered it to cold seizing the bottom end just a small amount on and off untill it got to far .then things seemed to stop.
only in certian conditions ,aparantly we had enough of that .
figured that is possably why it is here and there .

would have been a lot upset but the new motor is pulling hard enough to make me notice .fingers crossed .



ran the oil they asked the sled to use .now they have asked me to run semi synthetic insted of the mineral oil .

any one got some reasoning on that ?
 
Sorry about this smart a$$ reply but why don't you let your buddy ride your sled in and out at that same spot? If he blows it up then you'll know its not the sled but the rider with bad karma:(

Funny you would mention that, most times it has happened he has ran it back to the shop go the demo sled and rode it all day with no problems.

I know they are looking into the lemon law issues, there is also a law about warranty and the issue that it has been in the shop for so many hours.

I know they also have tried to talk to someone at ski-doo but they jsut get stuck on hold for an hour a time, with out ever talking to a human.

Again not looking to bash on Ski-doo but looking to see if anyone has any ideas of what it would be. I ride the same sled and so does several other guys we ride with, in all I think five of us got them last year, thison has bad motor trouble, one never would run like it was suppose to and don't know if they ever did get it working or not, and one had bad clutch issues. They all had the same standard clutch issues but one broke a primary and went through belts like candy.

Thanks for the thoughts.
 
Was the oil pump changed,oil cable out of adjustment,restriction in coolant system.
 
further to my comment on oil injection, could the timing be advanced to far causing overheat?? Could your coolers be blocked??? Some things to check. At the very least put a water temp guage on it and monitor it like crazy next time you ride...:)
 
I had an 02 800 with a RKT head go down because I ran it without a thermostat---a cold siezure and a lean midrange---a DOO thing:mad:

If the clutch is way out of balance, it could take out the crank---a Polaris thing:light:

I still think its bad Karma:(
 
Possible fix for motor problem

First of all, I have never posted anything on here for the 5 years that I have been reading all of everyones BS, so I thought it might be time to help out if I could. I rode with a guy last year that had the same thing happen 3 times. He lost his motor in the same place on the trail every time. It did seem a little strange. After they figured out that the oil pump was bad, he has not had any problem since. Try this out and see if it works.
 
Time for an investigation?

My brother experienced a similar problem on his XZ two years ago. After the third engine was installed the dealers mechanic found the oil line from the Tank to the pump had a kink in it and the engine was not getting enough oil. The line was re-routed and we increased the oil consumotion to 40 to 1, The sled has been running strong ever since.

I would also follow the recommendation to call BRP directly and file a claim with them, it never hurts to get the factory involved. I work for a large company and part of my job is warranty administrator, when I receive complaints directly from the end user I take the additional time for a second review and look for ways to keep the customer happy.
 
Like others have said I think its an oil problem, or lack there of. Add some oil to the fuel tank for a while and see if that helps??
