Just recieved our GPX Raider 90 and would like any info from people who have upgraded these or Unison Desert Cat 90's for racing MX? We live in Alaska and our home track is alot of short straights and corners. Very sandy and deep in corners. The other tracks we race on are good dirt and hold up very well with longer straights. Works shocks are a must addition. I need a pipe, clutch set up that will give instant power, throttle response from idle to mid range as top speed isn't as important for us. Maybe clutching to keep rpm's up and on pipe? Any help would be appreciated. I will be posting my .02 first impressions this weekend of our new ride. Thanks.
