Well southern Wisconsin got some snow and I was finally able to get some seat time in on the race sled. First off I can tell you that this is the first Nytro that I have ever ridden and it rocked. I put on 100 miles this past weekend on fair to good condition trails and the Nytro was great.
First off Handleing:
With my stock RTX front Fox shocks I set them up the way that some of you recomended. I have 90 psi in the shocks, with 8 clicks out from hard on the compression and 4 clicks in from soft on the rebound. It was a really good set up for the front end for my liking. In the rear I am running Fox race shocks and these bad boys were stiff when I had them in the middle for high and low speed. After riding the lumber wagon for the first 10 miles I turned down both the high and low speed about 4 clicks each. It made a world of difference when I did this and moved my torsion spring to the medium setting and it worked well. It was still stiff but it will be good for racing.
The sled cornered flat...very very flat! I have ridden and raced for the yellow brand my whole life from the old chassis, to the REV to the XP and I can tell you that they dont corner as flat as the Nytro! Long sweeping corners through the patato fields were not a problem at 70-75 mph on the Nytro. I stopped at one end of a field and got onto my dads 2013 Ski-Doo Renegade X and I was able to corner it at about 65 mph around the same corner but the inside ski was lifting the whole time. I also ran into some quick 90 degree switch back corners around a woods line, and the Nytro was very easy to pitch around the corner and change direction from left to right. Last season Nathan Titus (factory rider) was telling me about riding the break with staying on the throttle to get the nytro to slide....I tried it and it worked like a dream! Getting th track to lock up quickly then staying on the throttle the whole time allowed the back end to drift right around the corner even with 160 studs. Through the bumps the front end was a bit heavy but it will be easy to get used to after you learn the piviot point of the sled. Oh ya the Nytro can fly to! Road approaches are easy to jump over with the torque of the motor!
Motor:
Fast! Like I said this is the first Nytro I have ridden and I was very impressed with the constant torque! I was riding with a friend with a 1200 Ski-Doo and we took off a few times together. He had more bottom end for the first 20 yards then I blew past and was gone! The Dynojet and auto turner seemed to make a big difference with the mid range pulling all the way up to 85 mph. The power was also very smooth as I know my wife will be able to hop and the sled and enjoy it as well.
Now my question for you guys is that I currently have stock clutching and gearing in the sled. What are you guys running in your sleds? What clutching and what gearing combo's are you using? From what the Factory team is telling me is that they are only gearing up 1 tooth for lake races to get an extra 5 mph out of the top end. What do you guys do for clutching and gearing?
First race is January 19th in Poynette WI on lake Wisconsin at Lakeside Bar and Grill. This will be the first round of the COR Powersports Series and from what I have heard the Factory Yamaha team will be racing this event as well. It is an off weekend from the USXC series and I have heard through the grape vine that quite a few factory pro's will be at the race so I will have my hands full in the Pro class with my debut on the Yamaha Nytro. If you guys want to come out to the race go here for more info. It should be a fast course being that its all on the lake, but wit the recent snow in southern WI their might be some good rough sections as well. http://www.corpowersports.com/schedule/poynette/

I spent the last 2 days playing with clutching. Ran Supreme and spring combo last year and it worked ok. After loosing a tungsten weight to a broken screw on day 2, I went back to stock and couldn't be happier. I just dropped 1 tooth on my XTX and it's spot on. Actually scared my the first couple runs over 2ft chop at speed. IMO, don't waste time or $ on clutching. With your exhaust/tune/etc I'm guessing you pull +9200 RPM anyways.
Good luck, go privateers !
