Note: If the stock gear is unmarked and the size is unknown or you are scratch building an engine and without gear. S&S recommend a gear in the middle of the size range. These sizes were used more often and should provide adequate gear clearance under most circumstances. When in doubt. use a gear from the middle to the small side of the range. because a combination of looser fitting smaller gears will give a harmless clicking sound but to tight can cause a wining sound. binding and premature wear.
