im suprised you like the series 4 track.....little more lug height but still narrower and a poor design compared to the camo.
thanks for that informative thread. just one thing you commented on is the falling flat on topend.ive noticed that on mine so i imediatley went in to the primary and added weight.i ride at about 5000-7500 ft and the sled came with 62g weights.it was constantly hitting 83-8500 rpm so i took a stab at trying 66grams.my result was bang on.i gained 15 mph track speed at 8100 rpm and it pulls way harder than it did before.top speed is about 86 mph.tks rmr1964
