For twenty plus years, these manufacturers have used a spring washer or dome washer along with a locking bolt to retain 4 stroke and newer 2 stroke counter shaft sprocket. A retaining ring is used on most 2 strokes. After a year or two of riding, many of these bikes develop an oil leak around the counter shaft. This often shows itself as streaks of oil lines on the face of the counter shaft sprocket.
