The sound increases as rev is increased. Push in clutch and sound decreases as winds down. Reverse is not near as noisy but is noisy. Locking down one wheel has no bearing on sound. Do 51 springs and shocks work with the 55-57? I have a road worthy 56 and I noticed recently it is noisy somewhere also. Must be the tires though, cause on the rack it is quite.
Thanks
