I hve a 02 800 ported-polished, vforce3, twin pipes stingers. Max power at 8200 rpm's. Drive clutch 72 wts, black/green. Driven clucth 70/48 black/red. gearing 22/39 74 pitch. I bought the sled this summer did not drive it yet, the guy told me at topend the rpms drop off? I don't know how bad? so its like it shifts out to fast, than cant cacth up? What kind of top end would I have with the 1.77 ratio?or 1.82 ratio? or 1.90 ratio? I want something that pulls like a train and still have a fair top end. Because I don't want to fly past the mach's, firecats and the have them blow past me. Thanks :beer:

i run 21-40 gearing which is 1.9, it didn't hurt my topend at all... even though i added a 136 at the same time with my hyperlight clutch... i wouldn't go any further than the 1.9 on the trails... in fact i'm prolly gonna go back one notch this year... just to play with it a little...

if its tuned correct (jetting) and its falling off in RPM on the top end swap a70- 44 or a 46 helix in or try a set of 70 g weights. with 1.77:1 gearing it should pull like heII all the way up to 110 maybe more. 72g sounds like a lot of weight for a twin piped motor IMHO, I could be way off on this statement. I am going to try 24/43 gearing this fall and agree with Bonz , gear it if you dont like it back off some. currently running 24/41 on a prox 700 with some mods with a 136" x 1 1/4"

i think you are right, but for short haul clutching, ie. corner to corner, the 72's won't be bad, they will just fall off on the big end, and i agree with your statement about the helix as well...

I would try the shallower finish angle first if possible, a switch to a 46 may be enough. If the 72 weights have a heavy tip that may do it as well.

I run 25/41 all around it sound like he is running out of gear. i run out with24/41 24/41 is good for trail riding but not for much more than 1000 runs

FC,

i run 21-40 on wide open UP trails and clock 110+ on the speedo, the gearing is not the problem... usually when a sled hits peak rpm then slowly falls off it is because of one of two things, too much weight in the primary or too much finish angle, depending on what speed things begin to fall off...

So it's in the clutching. With a 1.77 ratio 115-120mph, 1.82 ratio 115mph, 1.90 ratio 110+mph? If I geared down to 1.82 or 1.90 would this effect my rpm's dropping? Or do I need a new helix or weight? Thanks Jason :beerchug:

i'd suggest dropping 2g weight in the primary first, alter the gearing to 1.82 then, if you still aren't pulling where you want to be then take out a little finish angle on your helix... like many have said, 44° seems to be the magic bullet on the Team clutch for a big twin polaris...

didn't know they made a 02 prox. bonz says you have a 700 prox mod 1.77 gears is 22/39 dont get me wrong but that is close to 600 gears this sounds like short runs trail rides I use 21/40 for 500'or 19/40 1.90 ratio

i hear ya, part of the reason i can get away with the gearing i have is the hyperlight clutch... and with the 136x1.75 track it allows the sled to pull it around better...

as they say, never fear the gear

YUP! I have a 1970 chevy with a 402 BB with 27" tires tall ( 10.5" wide) and 4 speed with 4.88 rear end gears..... to say it can jump off the line is a under statement!
