What helix should I use in my 2005 700 rmk. The track is a 144 x 1.625 lug height. I have a slp pipe system, stock primary and secondary spring. I plan on gutting the air box, holtzman atacc, 21/37 or 23/39 gearing are my options. 450 main jetts. I already have 10/64 weights, 150/310 primary spring. I am looking for some more midrange pull but I don't want to lose to much top end speed. My riding is trail and off trail. Elevation is 1600-2000 feet. I have a chance to buy a 64-42-36ER or a 66-44-46ER/66-42-46ER helix . Would either of these work for the flat land. Stock helix is a 58-42-36ER

Good luck on that. I would put it on snowest forums, see hat you get. Lots of good clutch gurus from what I have seen on there.

my GUESS is you would be better with the first option helix with that set-up.

Everything that I could find on Snow West was for mountain riding. I need some flatlander clutching. I thought I would find the answer here because this site seems to be mostly Polaris.
