There is a gearbox that Jim K. supplies with the new ratio final drive that
mounts on the speedometer drive that changes the gear ratio to feed the
speedometer IF NO ONE HAS MESSED WITH the original gears that came with the
3:07 final drive and stock TM-425. Give him a call to see what you might
have available.
