Yup, they are completely capable of making big power. That has never been an issue, but at a high cost. One of their weaknesses is the primary clutch. Not too bad up to about 200hp but after that thing's can go sideways very quick, on top of being a tuning nightmare and typical BRP patented heating system. It was never design for those loads and BRP never intended it to be.
So for a reliable strong performance a clutch replacement is recommended. I don't remember what was used on Banners but it was around a $1500 touch i was told.

I can vouch for the 1200 doo as I’ve had one since 2011. The best way to make these 1200’s run is hands down a motec system and get rid of the brp ecm completely. I will probly keep it forever as the only other power that is the same boost psi to psi is the apex, but a lot less weight. The primary clutch does need upgraded after the 200 hp Mark. I built a 1200 my buddy built a nytro and the cost was not far off in the end to build. But it all depends on how you want it finished. I built my own tunnel extension he put a cr racing tunnel on. I really thought I wanted a sw until I tried one, unfortunately I personally was disappointed with it. I would go back to a 2 stoke if I ever bought new as much as Yamaha has improved the 4 strokes they will always have the extra weight of the motor. JMO not bashing any brands just my thoughts.

After you spend some time sledding in the east Ill agree with Lund. Four strokes are growing and growing on that side of the country. Who wants to be rebuilding 2 smokes every year anyway.

you don't know what your talking about, say rebuilding every yr, not even every 3 yrs....actually never needed to rebuild any doo. I'm sure there have been a few but not like you talk...

Good post, yes the 1200, sled to sled is more comparable to the Apex but with less weight.
The 1200 never became the desired 4 stroke build mostly because of the cost. While a Nytro could be pumped to about 250hp with no more then a turbo kit and minor clutching.
The 1200 required complete clutch up grades and a different ecm just for starter's.
Though the motor was far more capable to make power over the Nytro, anything over 250 with a Nytro for long term reliability required engine modification's like head bolts, connecting rod changes. Thus why the Nypex became so popular with big HP guys. The Apex motor could deliver 300hp with no modification's.
From what we are seeing with the Winder is it fall right in the middle of the Nytro 1049 and the Apex 998 quad cylinder motor for big power applications. 270-280 with no motor mods reliably.
The new Winder 998 triple is much stronger then the Nytro 1049 triple so now the cost involved in building a big HP sled has been reduced drastically.
Now a simple bolt on and plug and play ecu upgrade will deliver the hp with a little clutch tuning the Winder will pull 250hp all day long for the next 10,000miles.
My 2010 Nytro cost approx. $35,000 to build, that is every thing from purchase of new sled to turbo to 174 stretch and suspension upgrades. It was a very capable sled and once done it cost me virtually nothing to play with for 6 season. ZERO issues.
My 2017 SW at this point in time i have approx. $20,000 invested in it and i'm sure it will run with my Nytro any day. I expect with final tuning and power up grade the Winder will come at less then $25,000. Not bad IMO for a 250+hp long term reliable sled.

The Winder you tried might had not been set up properly, i do know if the skid is not set up they carry a lot of the weight on the ski's. Once set up they feel very close to a two stroke in general handling. You should only feel the weight on hard set snow but then most all sleds feel heavy then. And if your trying to man handle it, like lift. I learnt never to lift my sled's, 4 stroke or 2 stroke.

Put on 5000 to 10000km a year out east and you will be rebuilding every year

Every. Year. Since 2003.

Two strokes don't last as long and four strokes are heavier and more expensive.

Four strokes don't feel as heavy blah blah blah.
Two strokes aren't as unreliable as they used to be blah blah blah.

:deadhorse:


F**k all y'all I'm buying an electric sled!
