My son just picked up a 95 Jag 440 fan. Nice well taken-care-of sled. But there is no steering response. Too little ski pressure. My first instinct would be to reduce tension on the front of the skid. Problem is, I don't see anywhere where there is adjustment on the front coil spring. Even my daughter's 92 EXT has a threaded collar down there. Anyone have any experience with this skid setup?
