I also tried out the SSI aling with the Heavy Hitters this year. Let me look up the specs of your High Country ans i can get you a bit closer on your setup using the parts you have. Ultimately a helix and spring change would really help but let me know exactly how you have the magnets placed and we can go from there. QUOTE="Joshua Smith, post: 1531732, member: 32445"]Ok so to revive this post a little now that the season is over and I am needing some more help. I out the ssi 54-68 weights in my primary to replace the 64gr. Stockers. I would assume this machine has a low altitude kit in it because of the 64gr. Weights. I did the stingray airbox mod and a super q high flow muffler which was on for the whole season. Changed to 21/41 gears for trail riding 7 tooth drivers and 2.25 track. Started with 63gr. Of weight and never got the limiter then dropped to 61 still no limiter. I am only seeing 8450 rpm at wot on a railroad grade and tops out at 85mph. I am putting a pcv on this year but I am curious do I need to go with different springs or helix to get more top end and rpm? I'm kind of at a loss I don't know if pulling weight out is the answer?!?

That would be greatly appreciated from the heel out I am running 3-2-0-0. Did you prefer the heavy hitters or the ssi weights?

So your High Country is clutched the same as my 129" ZR which is so far out in left field it isn't funny. Sleds are quick but have terrible response and backshift.

I'm realy surprised you like all that weight in the heel with the stock secondary. How is your backshift ?

If your budget allows a shallower helix and spring change in the secondary will work wonders. I'm running a 50-44 with a 175-240 Dalton. Much better response with this setup and very cool belt temps ( I'm using the stock belt).

If you want to work with the stock secondary I can recommend a primary spring change that will get you close to 9000. I have every factory arctic primary spring offered as well as many Daltons . Stock is 35-215. There isn't anything offered spring wise that we can increase the upper rpm without raising the engagement. I'm guessing you should be around 3000 now with your setup. You'll end up around 3400 with a spring change.

As for the SSI vs Heavy Hitters I'm undecided just yet. I have them both working very well. My sled will run 103-104 with either in good conditions and that was with a worn belt hitting the rev limiter. I feel it will run 106-107 easily. Now in the snow it will run mid to upper 90s. Before it would struggle to 85. I think for the average guy the SSI weights are a great choice . They aren't as aggressive as the Heavy Hitters and therefore are easier to tune especially with a non- torsional secondary.

I've spent a ton of time with mine. It was a complete dog stock in any type of snow. Now it is very fun to ride with almost 2 stroke like response.

It sounds like you have these clutches dialed in so I will definitely take your recommendation on the helix and spring for the secondary. My backshift is sluggish but not in bearable. I struggle to see 85mph on good conditions. If I go with your recomended spring and helix for secondary, what should I do for a primary spring? I engage at about 3050 right now. Also what do you think I should do for magnet placement in my weights?

I went with a 50-44 and 175-240 spring. Id leave the stock 35-215 primary in. The decreased upshot with the shallower angle/ stiffer spring will bring you up close to where you need to be.

My setup will be a bit different then yours because of track length and lug height. I will look at my SSI weights and see what I have for the last set up with magnet placement. If your OK with the factory backshift , you will really like this setup!
