Picking sprocket size:
Higher tooth sprockets give you higher torque and lower top speeds, while fewer teeth will give you less torque and higher top speeds.
48-tooth sprocket – Highest torque, lowest top speed "breaks spokes"
44-tooth sprocket – Great balance between torque and speed "Recommended but breaks spokes"
40-tooth sprocket – Higher speeds, lower torque, safe ride "its okay but still sometimes it breaks spokes"
36-tooth sprocket – Reaches ultra-high top speeds and a faster finish, least torque and slower starts
Lower than 36 is the best performance, gas saving, and yeah no more breaking spokes.
2-Stroke engines offer more torque. They use a Gas/Oil Mixture. You don't have to check the oil separately.
4-Stroke engines offer a quieter, less torque smoother ride. They emit less exhaust and only gas in the gas tank.
