How did your body feel the next day. Can I give you some advice after watching some of your video? I know you said in another post you haven't really done this before. See how you pulled over around 10 mins in the video to let others by? That is good, and I complement you on that, however, next time try to pull off even more and not on a side trail. As you can see you have several quads coming by, and for example the one guy stalled, right where you were parked 5 other guys could of passed him right there. In other words, you took away a passing lane. Also, I complement you on looking back to see if other racers are coming up on you, but again, you will hear them when they get to you. I didn't watch the whole vid, but if you hear them come up on you, do exactly as you did when you get a chance. Sometimes there isn't any real area to pull over for a few miles. If the other riders are any good, they wont need you to pull over 99% of the time, and you will also notice that those A and AA riders wont shout at you or anything like some of the other guys. I hope you don't think I am coming off as a dick, I am just someone that has been into XC racing for most of my life, well until I went into the service, but now I am getting back into it.
How did your body feel the next day? My cousins went down and said that saw an XX, so I assumed it was probably you. When I raced my XX a few times in WNYOA and then a winter series, it was like I was the most popular guy at the track before and after the race because everyone was coming out to check out this machine. This was back in 08/09 when they first came out, and no one knew what they were.\
As far as setting up your quad. Your tires are too big in the rear. What I ran on the XX was RZR2's all the way around and 22" high both front and rear. A lot of guys run with 1" higher in the front, but I found with this stuff, if you have even size tires, it turns better in the tight stuff, more weight on the front, my opinion though. Also, you could try some of the DS450 front shocks. That may help.
Again, I hope I didn't come off as a dick to you about some tips on your racing. Where abouts are you in PA? If you are close to NY, there is a NY series as well called WNYOA. There are only a few tracks here that are like Evansville, which is full of moto. Both of those are Nationals, one on the GNCC circuit. Wish yo uthe best of luck with it.
