the r-12 is no contest for the dalton helix. personally on the big twins i like more weight and smaller helix.

a 48-38 helix should be a hard hitting helix, and then some 10-60's

gearing i would drop to a 22-40 area,

what angle degree is on the r-12?

so is my dalton helix good enough? its mostly a trail sled with some off trail playing.

thats my plan with the 10-60 weights.

whats ur set up u just told me would do? is my set up bad? now i have a stock 10-58 in my primary, stock for 600s in the 2002 year i guess? i replaced the spring to epi cuz its from my friends pile of springs lol, brand new and got it tested. to 150-280.. that woke up my sled. the dalton was on when i first bought the sled.

the polaris is a 50-36, but its not 50 degrees for very long. on a twin i think you are better off with a progressive 46-36 or 48-36 helix and then try to pull the 10-60's if you can.

its tuff to go to a bigger helix and bigger weights. if you go to a bigger helix and stiffer secondary spring you might have to stay with stock weights.

i personally did a silver blue spring and a straight 36 helix with 60 or 62 gram wieghts and the thing pulled hard from start to finish. but some guys like the bang a big helix gives them. there is no magic setup, run what seems to work for you.

ok i will try out smaller helix. where do i find the progressive 46-36 or 48-36 helix

and what is the different between those springs?

dark blue/ white- 120-310
almond/blue- 150-310
mine- 150-280

what is the different with spring strenth? how do they work? i still have 10-58s. so which do i try to play with?

i guess honestly i would leave the clutching you have now in there and get to a 20-39 or 20-40 gear ratio. alot of 160 hp sleds with 121 tracks are only running 22-40 or 23-41 gears.

you probably wont loose any topend speed since with your stock gearing and that big track you never reached top end of the gearing.

think about it, drag cars go from 3.5 ratio to 4.1 ratio and its night and day, or in your truck, at 70 mph give it gas how fast does it accelerate vs putting into 3rd gear and giving it gas.

that gear change on a sled is huge, from 1.69 to a 2:1 ratio, pfft it will feel like a new machine, especially off trail.

21-42 should fit the chain nicely!

why did i think you were going to a long track? double check with a polaris dealer that the gearing will work with your chain. 22-40 will also work and be an increase in snap.

if you are staying with the short track i would go 22-40.
21-42 is 85.90909 mph @8000 rpm, 1:1 shift ratio.

21-41 is 88.00443 mph at 8000 rpm at 1:1 shift ratio.

22-40 is 94.5 mph at 1:1 at 8000 rpm.

23-39 is 101.3287 mph @8000 rpm @ 1:1 shift out.

if its going to be a wife sled in the future, i would go with the 21-41 setup. if the sled in average conditions will just barely go over 100 mph any how why not gear down a little and get there quicker. if it was a bigger sled i would say leave it stock, but for the average guy gearing down a sled is a cheap way to add good power to the track, you still will get to 100 mph just a little quicker.

ok im having issue with my clutching? or something. sled seem to fall on its face at 70-73 mph at 8000 rpms on a wide open long feild, happened on my last trip, did 202 miles that day.

i did not change my gearing yet. cause i left to go on a trip in the last min.

one thing i noticed is my belt seems very loose, like 2 to 2.5 inch of play, so i tried to adjust the 1.3.5 thing on the secondary, number 1 means closes the clutch more. and 5 means open up right? i put it on number 1, test rode the sled, and its not tight enough. does this mean my clutch button is worn? my clutches is completely spotless. everythings good. just quits topend power at 70ish mph. while the same sled i was riding with in the group is way ahead of other friends 700 xcsp. and mine is failing. stays with z570fanner

right now i still have the set up of 10-58, spi white/yellow spring tested 150-280 lbs. secondary silver/blue poo spring, in hole number 3 helix, 52-36 dalton. should i try hole number 2? or what? im stumped.

its a 2002 xcsp 600, engine is rebuilt, only 214 miles on it, carb is spotless, stock jetting is 430 it has 420s now. everything works great. takes off fast, but quits upperend. bellows, ves spotless and no tear. stumped!

belt is brand new 080 poo belt.
