Looking to put together a very quick 0-100 mph machine.

Is 24/41 a good start. Any chain issues ..? Slack.. fit etc.

Using a HSP 38 x any clutching suggestions..?

24/41 will still go over 100 mph , infact with overdrive it will go right around 110 mph. with a 76 link chain it will be fine , it does have a little dog leg in it but its safe. if youhave other gears and chains I would go steeper then 24/41. This season I am going to run 24/43 , the last 3 season I have run 24/41 on both my prox and xc ! with good traction it comes out of the gate harder then stock!

How much difference in performance between the 41 and the 43. I know the ratio changes by .10 but on the snow how would it compare.? Bottom, mid and top end.

Does the 43 work more efficiently in the case.?

I am using 25-41 in my '02 700 twin. Tried 24-41. Not for me. I like stronger mid range with the 41.

????????????????????????????????????????????????????????????????????????????

24/41 is stronger in the midrange then 25/41..... ever tried starting off in second gear with a manual trans car? hard to get it moveing isnt it , same idea with a gearing change on a sled. in many cases going from 25/41 to 24/41 guy are reporting they pick up low end performance and top speed on some sleds increases! I cant conferm the higher speeds , my testing spot is just over 800' with very little shut down area.

Also seems to not have much of an arc around the tensioner=less friction. I run the 38X and like it with 66 gram Polaris weights, 165-310, EPI Black or HSP white(?) Totally off the subject but this set up along with the usual mods makes this sled a wolf in sheep fur. It runs about 8300 rpm on an uncalibrated tach and speedo and will bury the needle with the stock 25-40. Mines a VES 02 700. Don't sell yourself short, these sleds are capable of some surprising things when tuned to the "Nth" degree. Cant waitto hear what works out.

Hello All I am Finally Back Online

I have ran 25/41, 24/41 23/41 in my 04 700 XC, I have quite a few mods, but 24-41 I have found to be the best combo for me.
I run the 23 only on the ice for 660 with a chiseled ice track.

24/41 pulls nice but these sleds aren't great top end monsters anyways.
I can pull 110 mph with the 24, and with my mods, my fuel mileage isn't the best, around 110 miles to a tank with 420 mains.
Track depth,studs/ driver weight, type of snow, all are in the equation, I run on groomed trails so I like lotsa grunt.
Hope This Helps

24/41 is a faster shift ratio good for trail and short blasts like 660/800' and you will be out of gear in less than 1000', and burn more gas. I ran 25/41 a 52/40 epi progressive with epi orange and 10/62 or 4 with po blk/wht and this pulled like a fraight train on the lake with my 02 700 38x is a coumpound radius helix and easy to tune. all depends on what u want

I have the 38x and mechanical Reverse. ( Gave up my electric start for torque arm , but I am drawing line at reverse) the largest bottom I can get is a 41 so I will work off the 41.( keep my reverse) Last year I used EPI red and Orange #3

My riding style is pretty simple. Woods roads, lakes, bogs , and open country occasional trails. Tend to ride with buddies 800 xc's,F5's, 700 xcs, 800, 600 ski doos.( light , med mods) clutching, helix, pipes.Studs.

Racing is pretty friendly but no one wants to lose. Distance 660 to best top ends.
Anything that makes for bragging rites over rum and cokes :beer: at days end.Wants to have 100 miles of fuel on board.

This year, electric start is gone. Torgue arm in, engine was torn down built back up. I am now going through clutches, then alignment. and deciding which gears. :dunno:

I am convinced the 25/40 causes a heat build up in belt softer bottom ( blew 2 belts last year WOT)
2 burn downs and a belly pan later here I am.

Glutton for punishment. :frech32: Can't wait for the snow.
