^^^If you look at the last chart posted, you'll see the gear combos you can use. I think your sled would be the 6.625 center distance chaincase, or the section on the left of the chart. If you go down the column labeled "chain pitch," you can look at the gear combos that are listed for your 64 pitch chain. How I read the chart is that you better not use the red ones, the blue ones will work, but not very well, and the black ones are good combinations that are recommended. The higher up the chart you are, the lower the gearing, so if you want to find a lower ratio, go up the chart from the combination you have now.

O ok, I understand now. How would i know how much lower gearing i should go with, could you tell me or would i have to find out how many teeth my gears have first? Not really sure what the ratio means for gearing.. So im gona need extra help.. Haha

stock gearing for a 1996 sport touring is 16 teeth on top, 39 teeth on bottom. I assume it has 9 tooth drivers. @7000 rpm @1-1 shift out you are good for 61.67 mph.
there isnt a lot of room to move on that sled. no need to gear any lower, and if you gear taller the sled might not pull it very well.

what were you wanting to do with it?
what are the wide open rpms of the engine? like if you punch it what do the rpms go to?
the sport non touring runs a 16-35 setup. and that is good for another 9-10 mph on top end. and then a 62 pitch chain. but you could save some money and go to a 17-38 gearing and be about the same as the standard sport machine.

I was jus thinking of getting better take off and possibly being able to lift the skis but i imagine thats not going to be easy if even possible with my sled seeing as its a 440 fan and long track. So i wouldnt want to try and gear up to get a higher top end speed either? My sled didnt come with a tach so i could not tell you. But if you know where to hook the tach up i can use the one from my old polaris sled to find out for you. What would the 17-38 do? That would give me higher top end right? I was tihnking of gearing down but i would definitely consider some better top end speed too. Either would be nice..

for some ski lift thats all in the suspesension.
http://parts.polarisind.com/Assemblies.asp #13, you can rotate them so they are a little farther away from #9. that will let the rear suspension compress a little more to allow better weight trasnfer.
http://parts.polarisind.com/Assemblies.asp

you see #17 the strap, you can look to see if yours has some holes above or below the bolt. if you make these straps longer, it will take some pressure off the skis, better for loose snow conditions, off trail riding, and take off.

its a balancing game between adjusting the rear blocks(#8 in first link) try to set them to the lowest or middle setting, if suspension bottoms out real easy, then set them up to the next level. the rear spring tesnion, and the front limiter straps.

Those links wouldnt work for me. I signed into polaris and it still wouldnt work but im almost positive i got to the same page as your talking about. You went to the parts page for my 96 polaris right? Thats the page im at. I think i got you about the rotating the blocks. Ill have to go check that out. I cant find what you have in the second link tho.

Ok there are 4 little blocks that i want to turn right? Correct me if im wrong. But the only thing i can do is move on of the blocks. The block in the rear has a hole for it. I cant jus turn it cuz it has notches so that it doesnt spin around or whatever. It does have the xtra10 by the way i dono if you knew. And for the limiter strap.. How far should the hole be that i would want to move it to? I dont see any holes very close but i do seem some down the rail. Not sure if thats the holes im looking for or not.

the holes will be in the straps. or look at the front arm and see if you see a bolt on each side hooked to the straps.

the blocks. you only want to mess with the rear ward ones. play with them and move them around to see what it does for you.

O ok.. I had already figured out i can rotate them. I did rotate the front ones. Should i switch them back to how they were then? I moved the rear blocks to the other hole so the suspension will go down more i think.. Right? I will check out the straps. I didnt know it was the straps i thought i was moving the bar they are on haha..

No good.. Yes there are holes in the straps.. But they are already so the straps are as long as they get. If i am correct in thinking im trying to make them longer so they hang more while sitting there? Or am i trying to tighten them up so they dont hang? sorry im confused.. But the straps are already as long as they can go.

If they're as long as they go, that's how you want them.

yep, thats how you want them. by moving the rear blocks back some it will let the suspension sqwat more when you sit on it. and it will let the front end come up some when you punch it.

Thanks guys. Too bad the strap is already as long as it gets. Looks like i wont be able to do much else. I did move the blocks and ill see what happens as soon as i get some skis then ill mess with the blocks some. I moved the front blocks too tho. Should I move them back to how they were? Is there anything else i can do to my sled to get some better take off or top end? Either one i would consider doing.

yeah, put the front blocks to the factory position.

for more top end you can try gearing up. but who knows what that will do to the take off power.

I did put an aaen pipe on a trail and it made some good power. and lost 7 lbs.

Alright i really need some help with the gears now. My gears and shaft are totally fucked. Im getting a new shaft already. Need to know what gears i can work with tho. Im planning on finding a whole set (chain and both gears) together. My brand new chain is destroyed. The nut came off the top gear and the chain came off and destroyed the end of the shaft the top gear and my new chain. So i found both gears and chain from rxl. The gears are 21 on top 39 on bottom and 66 pitch. Will this work for me or not? I dont think it will but i want to check. Like you said my stock is 16 on top and 39 on bottom and 64 pitch. If anyone has some gears that may work let me know i want them real soon.
