I am looking for any advice to make my boy's 550 summit easier to turn for him. Is their any aftermarket skies that will do this? Will letting the limiter strap out help? Will stiffening up the front track shock help? The current set up of the sled is, stock 6.9 skies in the narrow stance , limiter strap set loose on flat ground( about 2" of free play in strap), all springs are on the softest setting. My boy is only 10 and weights about 80lbs with all his gear on. The sled works great for him except by mid afternoon he can no longer make it go where he wants it to.
