If you want to win, you gotta run the number! The MPS Air Throttle Stop is the best way to adjust your ET. This is the best product ever designed for slowing down a bike to run a specific index while still maintaining high MPH. The MPS Air Throttle/Stop can be used in several different ways. It can take the place of a launch rev limiter or it can be used with timers to slow a bike down consistently to run a specific index. This is the only NHRA legal throttle stop for a motorcycle. When used as a throttle stop it is wired to two timers that control when and how long the throttle stop is activated. After leaving the starting line the carb slides will drop to a preset point where they will stay until the timers deactivate it allowing the slides to return to wide open throttle. Through all this your hand remains at full throttle. It will not turn your throttle grip! The slide height can be adjusted to any position from idle to full throttle. The speed that the slides open and close can be adjusted independently of each other and can be made to open fast or slowly. This lets you dial in an easy roll on or roll off the throttle. Using the throttle stop right off the starting line can eliminate wheel spin entirely for the ultimate in consistent 60 footers. When used to control launch RPM you turn the throttle wide open but the carb slides will only open the amount necessary to hold the motor at the desired launch RPM. When you release the clutch or button the carb slides raise to the wide open position. The Air Throttle/Stop comes with a throttle cable, electric air valve, air tee, air line, and installation instructions.
