Clutching the Nytro

[NB-NYTRO]

Whats RPM'S should this sled be clutched? I have heard 8,800. Is this correct? I installed my clutch kit and I'm trying to get it dialed in right. I got it now to get to 8,800. It goes to 8,500 off the line and then pulls to 8,800. It pulls harder then stock. The backshift is alot better then stock. I'm still not impressed with with the top end. I thought I had a good nytro as I was pulling 9,100rpms in powder with stock clutching.. now I don't know what to think. I went up to a 22tooth top gear. would having the primary machined for o/d help? Would I lopse on the take off? Am I expecting too much for a sled with only 539miles?

Mine has low rpms in powder. stock clutching 8250-8400 app... After clutchkit installed it pulled 8400-8600. Last night I put in a diff primary spring to rise the engagement alittle and now the rpms shoot up to 8800-8900 in powder. Havent got the yime to test it anymore so cant tell you how it runs. Ill do alittle drag with my cusin this weekend. then we will se how it runs....

8300 looks good to me from a dyno.

For best acceleration with a rubber non-studded track on snow 8k rpm holeshot climbing to 87-8800 mph for best acceleration & top end.
