Well... im a rider that is not into trail, the trail is used to get us to the "playgroung" im a very aggressive rider my time is mostly spent in short runs, minner cornis drops, 90% of what i do is jumping, im wanting to get fast ,quick responce, the jumping i look for is up hill or cresting over a ridge, as for the sled it is a 92indy with a "98" 700 twin v-3 reeds slp-pipe&can "d" slide carbs, right now the clutck is a 10-62 with new blue spring, the (cvt) is a "01" cat button style with a 53* singel angel, yellow spring, its spinning 8200, i have to replace the helix so i wanted to see if there would be a diffrent helix that might fit my "style" better,iv learned a lot about "reading" the wash on the pistons and re-jetting accordingly, the elevation changes we go through in a day is from 2200 at the truck to 4700 ta the first "playground" up to 7800 + on the BIG play area, well thats how i gide,,,,
