Haven't seen a shilter paw adjuster in a long time now that they just use a centering pin.
Here go's, put the bike in third gear, loosen the lock nut then adjust allen screw or whatever it has, depending on the year and model, there are a couple of special tools for doing this, but can be done without them, anyways adj. the screw untill the spring pressure and free play is equal on both sides of the shift lever travel, then tighten the lock nut and recheck it. Boy this brings back some memories, thanks Dan
