arms reduce friction by 50 percent for increased fuel efficiency
and torque.

idle speed control valve to provide easy cold starts and
flawless fuel delivery in nearly any condition, from below sea
level to 15,000 feet.

assembly to protect the starter motor.

  • Stainless steel exhaust system features aluminum heat shields

and a screen-type spark arrestor for great power with minimum
noise output.

maximum cooling efficiency and is positioned high in the frame
for optimal protection.
