BOYESEN Quickshot 3 APC-3

Carburetor hesitation and bog rob you of throttle response when you need it most. The BOYESEN Quickshot 3 APC-3 eliminates that dead spot with a high-volume vertical check valve that meters fuel with precision across all throttle conditions. Whether you're tuning a stock engine or pushing forced induction limits, this bolt-on upgrade delivers the instant, linear response that separates competitive setups from the rest.

The tunable leak jet allows you to dial in fuel volume and squirt duration to match your specific riding conditions—no guesswork, no compromise. Combined with 25% increased fuel capacity and investment-cast construction finished to tight tolerances, the APC-3 transforms how your carb responds to input.
