First of all i like the sled and it has great potential. New it would rev 78-7900 rpm, now i have 650 miles and it only rev 75-7600 rpm across the field or lake. Ive checked the hose routing and leakage on the solenoids, tried new belt, air filter clean. It doesnt miss or seem to lack power or speed. Has anyone else experienced this?? Looking for possibilities-thanks.
