not for a average middle age trail rider 5k is nothing. plenty of 10k sleds out there just getting a first top end. 5k for a kid or boondocker/drag racer yep almost dead.

I agree but I wouldn't be ticked if my sled blew up at 5k. How much longer you expect it to last? 10k is a stretch.

In the small group I ride with, there is an xc600 with 9900+, a Fusion 600 and a SB600 that both sold with over 10,000 but still running, a Cat 700 EFI with over 12,000 (and the speedo has been out the past year), Yamaha 700 with well over 12,000 (speedo broke on that also). Before you point it out, I know all of those are either carbs or the Cat EFI, which isn't EPA-compliant.

Just saying all of this since I don't see why a 2 stroke can't do 10,000 without an issue. Perhaps you meant though with the Pro 800 it doesn't matter, since no one puts 10,000 on a mountain sled.

I think you have to look at it in the terms of how hard are the mile? 5000 miles on a sled I own is more than equivalent to 10,000 miles on a trail sled. I ride it like I stole it and I know many other guys who do as well. Also in the post above your relating to 600's and a 700, its a known fact that the smaller cc engines will far out live the 800's. The 8's cylinder walls are thin and there's a lot more rotating mass. If I actually let myself get to 5000 miles without rebuilding my sled and it went down I would kick my own a$$. That's just crazy, but then again I have no idea how you ride your sled. depending on how you ride it should be the determining factor on how many miles you can expect out of your sled. Although I haven't been able to get 3000 out of mine yet, I would rebuild it if I do make it that far before it blows up again.

it is 60% rider I trail ride with a few old guys from time to time both have cat 800s with well over 15k on one and over 10 on the other. they ride groomed trail and some times hit 90 on a lake. the 07 800 has 15k or more 1 top end at around 11k I helped him do it.looked like a sled with 3k on it. but his last zr800 had over 20k on it when the crank gave out.

The GIZMO? C'mon dude. The Gizmo is not going to save these motors. If it was the company making it, Redneck Racing, would still be in business. They are not! The Gizmo only helped the people that wouldn't properly warm their sleds up. The guys that would jump on their sled and pin it. When the cold flash hit the motor locks up. Its call a cold seizure. Hopefully everyone else has a good understanding of the 2 stroke motor and the GIZMO will never be brought up again in the talk about fixes for the Poo 800. If you want to pay me for this lesson on cold seizures and what the Gizmo does you can PM me and I'll give you my paypal address.

really DUDE!!so your sooo friken smart tell me what happen to Redneck????? then you send me the check!!!oh and does the Gizmo prevent the cold seize you talk of YEAP!!!but again there smart one tell me what happen to Redneck Racing? this should good!!!oh and they are not OUT OF BIZ like you say..

I am sure my Max has over 10k on it now, speedo don't work. I got it blown up at 6600. The previous owner left it for dead and severely abused in the maintenance department. i have run it for 4 seasons now but it has a new 700 top end. Original bottom end but it get a lot of oil. Most the old carbed motors will run long no matter who made it,,,dang EPA, Gonna burn the mattress tonight

Polaris was putting out a bunch of reflashes for some time. A lot of that was due to mid range bogs and a mid range lean issue. They had to lean it out a bunch to meet EPA regs. Some of these sleds went down due to a mid range burn down but not that many compared to the ones that went down from the pistons slapping themselves out of whack and either scuffing or busting a skirt off the cylinder or piston itself. Polaris won't admit that there is a problem. And I'm not exactly sure what they did between 2008 and 2013 but I do know that the pistons are still the exact same. I've heard they thickened up the cylinder skirt to keep it from breaking off but that to me is just a band aid. Ski Doo has a thinner skirt than Polaris and they seem to be fine cause they have properly fit pistons. Some claim that its the short rod ratio, but Cat has a shorter rod than the Polaris and they're bullet proof. There is a really good thread on Snowest, I'll see if I can find it.

ya DUDE they are not they same pistons...in 10 they went to a new manufacture of pistons they blamed the piston manufacturer at first then same issue with the motors...I do know what they did in 08-13...I kept track...

the gizmo? I'll give you $4.99 for one, heck, I'll take 3 for $13

Lol, Those things were more like $299. A guy could make one from parts found at Menards for about $5. And the sad thing is they actually had people buying them. Apparently people with a lot more money than Buck-85.

The other sad thing is people actually thought their sled running at 160 degrees was a good thing LOL

they where tested by Mechanics not forum mechanics.....

From what I am reading most of you folks ride way harder than me. If I do pin my sled it may only be for a very short period of time. With that being said I feel confident I should get around the 5,000 mark with no issue's or perhaps longer if I keep the sled.
By then, 4-5 years later, there will be something better again and if I still have the ability to ride will switch. Maybe by then I will be ready for a one lunger. LOL

Tell you what rispol, since I now have a pair of 2013 800's (RMK & SBA), I'll join you on "engine watch". It sounds like we ride in a similar fashion and about the same amount of miles. I put about 1000 miles on the RMK last year, which was the result of more trail riding than I planned on for this sled (hence the SBA purchase). The SBA (with zero miles) will probably get the majority of the miles next year and the RMK will be reserved for strictly off-trail. Between the two, I figure it will take at least 7-8 years before I'm in the 4000 - 5000 mile range on either. By then, the odds are good that I will be ready for a one lunger.

I haven't read all the posts lately, but figured I would give a little update and info.

My riding buddy tore open his wife's 2012 RMK 800 yesterday. 1700 miles only ridden at high elevations out west. Did some quick measurements and found out that the cylinders are pretty far out of round. Also the cylinders have a taper. The wear on the walls look actually pretty good, though the pistons are definitely rocking some in the holes. The pistons are not the same size between the 2. Both pistons have some deto marks on the ring landings. The ring gaps are to wide and have pitting on them.

The motor is using more than enough oil. He had turned up the oil pump when new, and might turn it back out some. He is using JT +4 oil.

The cylinder walls are pretty close to the same thickness as the Doo 800 cylinders that were sitting next to the poo on the workbench.

Overall, the engine wasn't close to perfect, but wasn't as terrible as some would have you to believe. Though it probably would have lived another season, it's going to get fixed properly, as my bud is a perfectionist. He isn't sure yet exactly how he plans to properly fix it, but the cylinders will be round and untapered before it gets put back together. And polaris rings will not be used, and probably not poo pistons, though the poo pistons are actually pretty beefy.

Just thought I'd give an update, cuz I truly believe the poo 800 can be made to be just as strong and just as bulletproof as anything out there, but it won't be stock. And I still believe it can be made bulletproof for less than the cost of extended warranty.

His own 2013 800 will be getting torn apart as well this summer. It has around 1000 mtn only miles.

This is good info for some of us that have been trying sort this all out. Granted, it's only one motor but it's probably more representative of the pattern than an anomaly.

you know, to many guys like your buddy this works out real well. If your mechanical and love to get to know your sled real good than it works out great. In reality it's not that big of deal if your that kind of person because you'd tear it apart anyway to keep a close eye on things. So for some it's a small price to pay for the best chassis and getting the motor rock solid. I may have to reconsider,,,,

B.S? you have no clue but I bet you read it on Snowest so you know everything....why do you feel the need to slander a biz??lets here what you have to say about the B.s....hurry go search for the thread on Snowest to get your response....before you say anything more i like you to know I am very close to the situation you cal B.S and I do know the truth so let er rip.....

So after 15 pages what have we learned?
If you like to wrench... but a 800
If you like to gamble.... buy a 800
If Polaris is your God...buy a 800
If after spending 10k and you have money left over to buy a gizmo, that may or my not work,... buy a 800
If your a trail rider who racks up tons of miles and doesn't like to miss trips....don't buy a 800!
Think that covers it. :p
