Completely fills the pump chamber with fuel, 2. Eliminates troublesome air and, 3. Provides an adjustable leak jet circuit for simple hand tuning. The Result: The ultimate in adjustable fuel injection. >Turnable leak jet maximizes volume of fuel and duration of squirt for all conditions. >Investment cast and finished to precise tolerances.

Boyesen Quick Start Function: The QuickStart system replaces your bikes stock hot-start system. You still pull the hot-start lever when starting a hot engine, but instead of leaking cool air into the combustion chamber, the QuickStart automatically shuts the accelerator pump down. Without the accelerator pump, you dont have to worry about flooding the engine or creating a fuel-rich mixture that wont ignite. Additionally, you can twist the throttle all you want, because as long as the hot-start lever is pulled, the accelerator pump will not work. The ability to twist the throttle means you can also introduce fresh air into the combustion chamber through the carb throat. All of this adds up to a perfect fire triangle. Performance: It works. Best of all, it works on an engine that has been cartwheeled and is boiling hot. If you can’t start your Keihin FCR-equipped four- stroke when it stalls, you need the Boyesen QuickStart!
