@ZR6000RR In case you didn't see it, take it as a reminder for the next time you try to disagree with me:

I threw away all my papers a year or so ago. I'm sure somone posted them back then, try the wayback machine on HCS

There is this one from years ago. Too bad they fired the suspension guy involved in the design of it. https://patentimages.storage.googleapis.com/b3/43/70/ef1cde860e1dd1/US11319024.pdf

You mean to say the non HO ac 800 was the fastest sled in its class!!?? But everyone on here says the motor was a turd, and the sled a tank

Gilardoni makes cylinders for AC snow, not sure who does the casting for the new 600 atv engine, but Mahle made a lot of cylinders in the past.

that will be 107 with the magic belt

No doubt there are hacks out there, but the oem's don't have all the answers either. When you talk about materials, and clearances, most of that is cookie cutter, and takes as much real engineering as jimwit does at his job (none). The processes and materials are well known. The oem's don't make their own cranks, or cast any parts in-house, there are a hand full of companies around the world that make that stuff. The "magic" (hp and reliability) comes from the ports, pipe(s) and tuning As far as SSI, I can't comment on the reliability, but I know of 2 that got put on the dyno, and both struggled to beat a stock 800 for hp

Bruce moved from ripping off sledders, to ripping off harley guys. I'm hoping it worked out the way I think it did

Just look at the guy's in snowless NY who have ridden more than Alaskan Karen

You vastly over rate some of the factory engine guys.. Just look at the abortion that was the poo 800. With what textron has done to the engineering, calibration, and test dept at ac, there are several shops with more experience and knowledge. It's a dam good thing Spaulding agreed to come back as a consultant after being fired. The good thing about using oem parts is low cost and availability, nothing to do with reliability...

Depends... A friend of mine has been doing this for a while.. We made mid 160s with a 800 top end on my 600, in 2007. Over the summer of 09, we built a 860ish cc f7 bottom end engine for my 09 sx sled Made mid 180s, with conservative timing and fueling (D&D f9 cylinders with stock f7 stroke) ran it all the way up at 9200 rpm, with a 5500 engagement. Both engines ran issue free till I switched sleds. Now that Ecu tuning is possible, there is no reason for a good tuner to have reliability issues. Hell a good tuner can make a engine more reliable than the factory, since they don't have to worry about epa.. Precision efi tune fixes the detonation that kills 800 ct2 s

the bewsts weren't holding up too well in these parts, and doo had a defective check valve that would fill the engine base with their magic turbo juice. Sled would fire, fill one cylinder with water, and stop. leaving you with rusty bearings, a bent rod, and twisted crank

Stuff the flap up into the tunnel with your ski, play kill switch tag, see if you could fill someones helmet with roost at road crossings. Play chicken by racing towards a fence opening that wasn't wide enough for two sleds of course it wasn't $100+ for a flap, or a tail light lens either...

No theories needed, you're a lying sack of shit. This is as made up as "yamha isn't going anywhere, I talked to the head" and "test rider told me the new engine is 870"

don't worry the catalog folks in Augusta got you with the pictures you want....

Like I said, they took extra special care of him, and gave him extended terms on this stuff.

I'm not sure what AC charges for interest on your parts account

He's not losing money on that gear at 75% off msrp fwiw

pc riot, which had the trail ski stance. Too long and pushy for me, but worked better in the twisties than poo Catalyst riot has the narrow ski stance so its pushy and tippy of course wtf do I know, jimwith says no one can tell the difference in track length

Ride them both, even the poo guys will tell you that the riot works better on the trails than the assault.

120/121 would be quicker/faster

rumor has it he was taking loans to pay floor plan (which isn't stupid if he paid off the entire machine at a lower rate than floorlplan, but is jimwit level if he took a loan just to cover interest is) He got more than one semi trailer of leftover clothing for pennies on the dollar, with special extended terms from the factory. He was also on the dealer council. As far as the factory having to take back machines, that varies from state to state. A while back NY added snowmobiles to the same category as other motor vehicles as far as dealer/franchise law. Prior to that the factory didn't legally have to take anything back, could set up another dealer literally next door an existing, etc. Now they have to take back current year machines.

I know you're a moron, but its not that difficult to under stand. They have to certify every single change.
