Just looking to see what you guys have done to improve the gas milage on an 04 prox2 700. I've read allot about the 03' models just didn't know if the 04' were different.

Same changes as the 03. Jet to 420, fuel and air screws to stock specs. 10-64 weights, almond/blue, new black spring, 3 delrin washers. Tighten the engine torque stop tight, no gap. 3211080 belt. Loosen the front track shock spring preload for less drag at the front of the track.
