Bikeman does sell low, mid & high altitude clutch kits for the Axys sleds. I believe it comes with their adjustable weights, a helix for the stock secondary, and primary & secondary springs.

Their stage 3 performance kit rocks. I have their stage 3 kit except I running SLP's 8K to 10K head kit

Based on my experience with a Pro RMK sled, and in order of effect on bottom end punch . . .
1) Higher compression head. Mine was a 13.6:1 Power Addiction head on the PRO. BIG
difference!!
2) Clutching for that head and elevation. Carls makes a GREAT clutch kit for this.
3) Pipe - SLP is a good choice. Small difference, but is noticeable if clutched right for the pipe.
4) Can - this makes little to no difference at all unless combined with the pipe it was designed for, and clutched for the pipe and can set. There is a weight savings though with the can alone, which makes it "feel" like there is a difference in power. I call it "pseudo power"
NO fuel controller is needed at 6-10k elevation if you use at least 91 octane non-ethanol. Be careful ripping on it at or under 6k elevation though. May be a little detonation at times and at the right atmospheric conditions.

One more option, is to get a set of QD sprockets from a '14 or '15 Pro and install them. It will take your final drive ratio from 2.23 to 2.38. Of course clutching will still be needed to maximize the potential of the sled.
Although a bit expensive, but IMO well worth the money is to get the Bikeman Bully Dog with the appropriate tune for your sled (I have their stage 3 tune on mine). For instance, If you get a stage 1 or 2 initially, it's $50 to get any additional tunes if you mod it even more. They also offer a "SnoWest" discount as well.

Here's what their tune(s) will do:
- Corrects base fuel & timing maps for optimum performance.
- Corrects fuel & timing maps for warm weather performance.
- Corrects timing above 8000 RPM for aftermarket pipes that like to rev for optimum horsepower.
- Corrects timing map based on pipe exhaust gas temp to better hold in the peak power curve.
- Corrects steady throttle lean mapping for better throttle response.
- Corrects Electronic Oil Mixture map for optimum motor longevity and performance.

The TRS set up. Forward, reverse, upside down, laying on its side... It's hands down best set up going. Just don't half azz it.

How do you know Dans angles. He doesn't mark anything? Dans set ups would be my second choice. TRS first.
Angle indicators are cheap.

Zollinger Racing Products makes some good items that drop weight on the clutch and on the recoil. They have a great product and a great price.

For the Axys, the Carl's clutch kit is their helix only. The primary and secondary springs remain the same. They also put a roller bearing behind the secondary in place of the washer(s). I am running an SLP pipe into a Diamond S titanium quiet muffler. More power and a big weight loss off the right side as a result. I am running Belly Buster 62 gram weights which work well at our primary altitudes (5,000' to 9,000'). The Carl's helix has two different positions to try too. The only mod that I have in mind (maybe) now is the Camso 2.8" track. I will wait to see how it works this winter. If it is good, I may buy one. It is light for sure. I hope that it is a good track in most conditions and doesn't turn into a toboggan on the downhills. The old Attack 20 Cat track had that problem.
Is the Carls helix the same as they used on the PRO from 11 to 15?
I dont think so but you can call them at 208.853.5550 to get accurate info.
Good old fashion compressed air!
