I have a 2002 superjet Freeride porting.175 compression dual38s r&d dry pipe running completly dry except the stinger. Stock ignition no rev limited and timing advanced. 14/18 concord prop stock nozzle n cone. I was very happy with my ski until I rode a couple others. No matter the setup dry pipe if b pipe they both have stock 62t motors with 185 compression no porting. Their motors seem like they pull thrue the mid range rpms wAy faster. Any suggestions on what area to make changes in to get mine to Rev up faster. Different size nozzle and cone mabe a different prop? Thanks
