what is then stock gearing used on the 700 dragon switchback? junk, needs lots of improvements.

22/40

I tried 23/39 and 22/39 i did not like these combo's ok on hard packed,but in loose conditions and deep snow it sucked. The sled seems to be out of it's powerband with this setup.

Tried 21/40 seemed very good,but haven't tried a hardpack run yet. i will reinstall the stock gearing 22/40 it seems the best.

My sled is stock 2600 miles no issues.

Always a trade off when changing gears.

If you find a combo that's better than stock let us know?

Good luck!

I've been running 23/39 in mine in flatland conditions (UP Michigan)...and found it to work far better than stock in both hardpack and deep snow conditions. Gained much midrange and low end grunt, did not personally gain any top end but maybe 1 mph or so, but I believe additional clutching changes may free some more there as well. I'm still over-revving with the steeper gears, so it certainly didn't bring my motor out of it's powerband at all...brought it slightly closer but not close enough. The only reason I ever went back to stock 22/40 was when I just had it in the Snowy Mountains at 10,000 to 12,000 feet (which is steeper gearing than Poo advises for that elevation), and in deep early-spring snow conditions there it was perfect and dead in the powerband where it should be all the time, whether climbing deep, climbing packed, powder riding, or trail riding. With 10-58 weights out there it was still over-revving just a bit...but never under-revving. But at flatland elevations I've found stock 22/40 to be very poor, and with stock 10-66's I'm always over-revving by about 300 rpms, with 11-66's I over-rev by about 250 rpms. These are with even a slightly softer finish primary spring. AAAND...I'm running a 1.5 inch lug Camoplast 9800c paddle track....which should further load the sled down but doesn't appear to at all. Next year I'll experiment with some 68 gram weights and see how that works. If they're too heavy I'll grind 'em. But I'm done for the year so we won't know until next Jan or so.

I didn't see huge gains with 23/39, but I saw some gains and won't ever go back to stock except for mountain riding. So I've found that Polaris has their elevation chart about one step off for my particular sled. Either that or I got lucky and I got a 700 motor that makes more power than others do. Who knows? I do have a high flow intake kit and have turned back my oil pump to about 70:1. Maybe those little changes made an imperceptable difference? Frankly I don't think so but I've never done dyno time so who knows for sure?

I guess what I'm getting at is every sled/motor/setup/rider style/rider weight/condition/desires are different. And you didn't mention what your goals were...only that stock is "junk." So what worked decent for me apparently didn't work well for Porker...so most likely neither of us is right for whatever you're trying to accomplish.

Individuals need to test and tune for themselves to see what works. Good luck!

they run better with both ski's, & a rider onboard

HAS ANYONE TRIED A 23/40 SET OF GEARS? IT SEEMS THE STOCK 22/40 sucks THE FUEL AND JUST SPINS FROM THE DEAD DIG.
