Ski Doo has not built a superior chassis since the 2003 ZX models Ski Doo has not built a superior motor since the rotary valve based motors I have been riding Ski Doos for twenty years and it is sad to see the direction BRP is heading with the delete the seat,rider front on the ski tips,which way am I going to get flung off of here chassis-to the motor blowing,clutch exploding,belt eating,drive shaft breaking,panel plastic melting,dpm issues,no riding for the next month 12000 dollar garage fixture that looks like something off of star wars. BRP pull your head out !!!!!
why am i reading this stuff?????? 04 800 stock, 1600m, new plug wires and rear shock.....hope thats the extent of my expenses for this year.
usually just pray for sno....will add gettin back to the truck to my list.

Xp 800r
Piston failed at 700km dropped into crank and got punched out through the cases. It all happened faster than a guy could say warranty. I disagree with Freekweet I would rather blow a motor a week that ride a zx!

Buddy blew 2 motors in 2 days. Both 2007 800R. One was a loaner. problems unknow so far.
Engines
1999 summit 500 2000 miles, no problems
2000 summit 600, 4100 miles and still running well (wifes sled) Im a little nervous, but am going to let her run it this year..
2000 summit 700, lost crank at 3200 miles
2001 summit 800, new pistons on recall, changed crank and pistons at 3k just for peace of mind.. (was my favorite Doo) through some testing determined alot of the ring issues were due to heat.. With head that allowed better cooling and hpc coating the y pipe inside and out I ran 2000 miles on 03 rings with no pitting.. Dynoport pipe, hps can, 16 wide track, team roller secondary, boss seat, r&m hood, simmons skis etc.. Should have kept her..
2004 summit 800, lost piston / ring / cylinder at 1800 miles, lost the crank 500 miles later.. Weak nun, weak running boards, weak tunnel.. 05 chassis now, Engine has 06 pistons and crank in it now, new carb boots (out of fear).. Every update I could think of..
I have rebuilt many engines over my life and the design of the rev chassis 800 is the poorest design imo Ive ever seen.. Only using half the pto seal is incredibly poor engineering.. Then, If you are going to use isoflex in the crank bearings, the bearing needs to be isolated.. As is, over time some fuel mixture will reach the outer bearings and will eventually wash out the isoflex.. You are guaranteed an engine failure beween 1000 and 2500 miles if you use this sled as intended (hard) in the mountains.. Either piston ring location pin failure due to detonation, rod bearing failure, or an outer crank bearing.. If you go longer you've either been living right, don't ride hard, or are telling a good story..

I am going to quote my own post.
Update- 05 has 165psi. on both sides and has 200+ so far this season...I did not mess with pistons or rings. Over 500 mi. on the XP so far since Dec 14. Flawless.

Mine too. As long as I trade them in every year...it's all good.
Love my 09. Never had a problem since my 2005.
This weekend we are doing a demo ride with Yamaha and Polaris. I have not ridden a Polaris since my 2003 Vertical Escape 159....Exxon Valdez. Yamaha will be interesting. always snuffed the dirt bikes that were 4 stroke back in the day...now look at the change.

And me to the list, 1300 miles, mine gave up the ghost

Three motors on my sled last year, thank goodness for warranty. I also blew the motor on my brothers sled while he was at college when mine was in the shop. So I guess you could maybe add me to the list. haha
lost mine saturday afternoon with the wife riding it. 07 XRS 800R with 2100 miles on it. i am going to tear it down tonight--looks like it is just the ring/piston on the PTO side but......

25,000.miles on skidoos since 99. still waiting to pop an engine. the 03.5 that beans had was mine and it was riddin hard. what are you guys doing to blow thease things up? i understand 01s&07s. the ones that blow 1 ,2 or 3. would that have happened on any other brand? i think if i popped 3 engins i'd switch to cat or pol. or trade up every year.
08' Xp Broken Crank at about 2500 miles. Had no 2nd year engine warranty but BRP is covering because the crank broke. This is one of the reasons it is hard to leave Ski-Doo.
06 800 HO--1800 miles and mag seal took out rod bearing and crank. My local shop that I bought it used from helped me out with parts. Thanks to them. My brother in law took out his 07 800R one week later--Warranty.
His dad blew his 05 800 a week after that.
I am scared but not enough to stop riding.
Mutt.

Haha I just blew mine yesterday. 02 800 highmark X RER. Still not sure why but it is locked up tighter than a cows A$$ at fly time. haha probably my fault, crankshop twins and a new throttle cable. I probably didn't adjust my oiler right or something.
Hopefully you didn't do the piston skirt crunch like my 02 HM X 800 did... at 1200 miles, cracked skirt, dropped a piece into the crankcase and broke the side out of it. Yuk. Basically trashed the motor except for one cylinder and the electronics... I would recommend replacing pistons at 1000 miles in a Doo, esp. with their 1-ring design and the extra clearance they run the pistons slap around a bit and fatigue. I switched to Wisecos in my newer engine, just make sure to warm them up adequately, no problems in the two years since.
'96 MACH Z crank shop pipes and cans, K & N filters, V- FORCE reeds,Hymark secondary roller, at 5200 miles freshened her up just cuz. Traded the poor thing in in October '08 10500 MILES, still fast and and strong, by the way belts lasted 1000 miles no problem. Freshened up was new pistons, rings and gaskets!
'02 SUMMIT X a little head work, can, K&N's, thicker gasket to bump compression, TEAM secondary. At 5400 miles carb boot cracked scored cylinder, rebuilt for good back-up machine. belts lasted 1000 miles, no problem.
'09 SUMMIT X stock, for now, belt 300 miles and counting, got my fingers crossed!!!!

I've had my '01 800 go 4 times since I bought it new. Two of the times it was the crank.. rod bearing failure at first.. now the latest breakdown is the piston skirt broken off, basically trashing the whole engine except for one cylinder..
I heard the '09 Doo's went to isoflex grease on all the crank bearings now (not just the outer pto bearing) .. pretty sketchy sounding sh!t to me!
