Ok my 83 honda big red has stock sprockets and I want to get more top end. It seems as if the machine maxes out in 5th gear so quick and the motor is just screaming. I wanted to know what is the best front and rear sprocket size to get as much top end as possible. The machine probably does 50-55mph now and having a hard time keeping up with all my buddies quad's. I would really appreciate some help in choosing the right sprocket size.
