858 Ripping

Cat wouldn't have to put the break-in mode on these sleds if guys weren't going out and just holding them to the bar the first ride out.
Broke almost every sled in that way and never had problems. Usually hit Cooke early with down to the dirt and no base. Turns out you get no where without throttle in that. Turns out mine has the same warranty whether it's full or half. Gotta love the internet. Everyone wants you to do what they're doing to justify in their mind it's ok.
Right, but with the low oil consumption these new sleds have they need the break-in modes (and in Cat's case RPM limiter) to have enough to protect them when doing it.
They do cover their butt because of people like me and they're going to do it even if people promise to break them in. Rode all my sleds hard, just like this, before they had break in modes and never had problems. The only trouble I ever had was trygstad 872. They told me to break it in really gentle. I told them I'm not much of a break in guy. They said they really recommended it because it was bored really tight so I did. Break in was over and it went at 352 miles. Wasn't even on it and almost went over the bars. They said I got it hot. Was 4 bars. Stopped and shut it off waiting for my wife and buddy. They came and fired it and hit 7000rpm and hit the bars. Cost me $1785 to remedy. If it's bored that tight I guess i don't need it and sold it. My last big bore experience. I even had a freeby trip at burandts and didn't go because my sled was down. For the record doos didn't run at 2, 3 in powder and 4 on trail. Possibly heat soak it when shut down for 30 seconds.
I have broke my in with heat cycles and varying rpm for the first three hours and I have never had a problem either. I personally don’t give a rats ass what anyone else does. I know heat cycles are the quickest way for the rings to seat. I also keep my sleds for at least 5 years. If rat bagging works for you that’s great but how long do you keep your sleds?
You don't care but it's rat bagging?
Maybe that was a bad choice of words. How about heavy engine load
I've had sleds with 3 or 4000 on them years ago before they went. More than acceptable imo. Especially years ago before all this breakin stuff. Years ago you just as well get it while the gettin was good because they weren't that reliable to start with. I quit keeping them very long because you started getting towed out of the mountains. Way more reliable now. I only go a year or 2 now.
I’ve always broke them in how I intend to use them. Just get on and go from day one, just don’t hold it at any given rpm for any extended period. Never believed in the heat cycling thing. I figure loading it in and out of the trailer preseason is close enough. Last few sleds have had between 3 and 5k when I sold them and they ran very well. Always keep sleds 5+ years.
I think more folks do break-in like Vern and TT which also works. There is more than one way to do this and I don't think either is wrong. What is hard on things is long periods of WOT under heavy load during the first few hours, and even then the engines will still most likely survive. I look at it as a small ask to not load the eng hard at WOT for the first 3 hours and choose to heat cycle the eng, burnish the brakes and break in both clutch belts. But I am semi retired and have time for this stuff!

If hard parts are going to let loose they will regardless of break in, Im more concerned about getting the rings to seat as best they can for best power. So I aim for a few heat cycles and then vary RPM and load early on try get some heavier load early. On a sled it pretty much amounts to me riding 100% like I normally do other than maybe being a bit easier and varying throttle more on trail in and out first day. I get heat cycles what the dealer does plus loading, unloading and general fiddle ****ing preseason. Im not good enough to hold it to the bars for a couple minutes straight off trail. Don’t think the OEMs want people to baby it during break in just to make it through warranty because they know it will either hold or it wont. Tight built motors or stuff with flat tappet cams require a bit more care on initial run in but we are talking production 2 stroke stuff here
Nicely done, this is basically what I do I am just not as good as putting it on paper like you did.
Exactly.
What don't you like about it? I haven't gotten out for a legit ride yet but mine didn't feel too bad.
Heard today that MDS had a good gain on track dyno with better clutching.
Latest SnoWest podcast with the guys from Ibex and Brady from SSI are claiming 20hp midrange gains with 7hp on top with tuning. An additional 20+ midrange with a Jaws pipe! Yes 40 hp total in the midrange. That seems awfully lofty to me. Speedwerx alluded to big gains to be had as well.
Conclusion: Cat left a lot on the table regardless of the exact numbers in both clutching and engine calibration. If we could get 20hp + midrange and 15hp on top with a stage 2 kit would be pretty neat!

Hopefully the ECU tune cat has in the works really steps up the pep in the 858 for everyone. 20hp in the midrange is a lot to be left on the table. If they still are getting these kinds of gains I will likely be getting Ibexx's tune and clutching when I pick an 858 up.
You guys say, "left on the table" like they just forgot about it or didn't perform enough dyno runs to locate the performance being found by tuners. I've got to believe the 858 was tuned specially to meet emissions requirements and that is why the aftermarket, WHICH DOESN'T HAVE TO MEET EMISSIONS, is finding additional power.
If arctic cat is putting out another tune, I can guarantee there will be minimal performance gain. No matter how many tunes they put out, they still have to meet the epa requirements.
