During the Fall of 2013 I caught wind of a new clutch "kit" that Moto was putting together for Boosted Nytros. After some conversation with him I went ahead and ordered one of these new kits for my Supercharged Nytro in hopes that I could get the stock clutch dialed in a bit better for the additional power coming from the Supercharger.
When speaking with Moto about this new Clutch Kit, he had the following to say that convinced me to buy one and give it a try.
This kit will replace the weights (with adjustable Daltons with a waaay different profile), both primary and secondary springs, primary rollers, and will require the use of an Ultimax belt rather than the Yammi belt...
The best part is, you will never believe how much difference this kit will make to the "ride-ability" of your sled.
It is so smooth, and drops clutch temps so much it is incredible.
It takes advantage of the low end torque of the Nytro, and engages at a much lower RPM than you are used to (this is what makes it smoother).
It isn't a terribly cheap investment, but as has been said many a time - "clutching makes a sled".
Try what you wish, but I will guarantee this is the VERY best out there for the Nytro.

Thus far all my dealings with PsychoSled have been VERY beneficial to my sled so I am more than willing to try out one of Moto's new creations yet again!!

For baseline performance comparison, this is where I am at right now.
Max RPM = 9,150
Max Speed = 83mph
Elevation = 6,500 for the test run on a smooth flat mile long trail.
Ambient Temp was negative in the single digits (-5 to -7)
Engine runs STRONG and SMOOTH.
GOAL with the new kit.
Max RPM = 8,800 in DEEP SNOW.
