Just got home from four days in valemont riding both bone stock 155 and 154 xp and dragon. Dragon was untouched, xp had the clutches cleaned and deflection adjusted. The d8 has a very smooth engine but seems a little flat on the topend. The weather kinda sucked but there was good deep snow, jumping from one to another on the same hill the dragon would never out climb the doo. This was out of the box to out of the box. Neither sled would come close to my D@D m9. but i liked both chassis,they make the m cat feel wide and low.
I think doo should have left about 10 pounds in this sled as i feel the d8 chassis will prove to be more durrable in the long run. Did not have handwarmer or belt issues on the xp at 180 klicks, 20 of which were pulling the m9 down from climina after it snapped a spider on the primary. As usual i think the best tuner will have the strongest runner.
MY 2 cents for what its worth.
