Description
Throttle hesitation and engine bog kill performance when you need it most. The BOYESEN Quickshot 2 APC-2 eliminates that delay with a patent-pending design that delivers instant response to every throttle input, giving you crisp acceleration from idle through the powerband. Whether you’re racing or riding hard, this bolt-on upgrade transforms how your Keihin FCR carb responds—sharper, faster, and more predictable.
Installation takes minutes with zero modifications required. You’ll notice the difference immediately: reduced hot-stalling, improved low-end punch, and the kind of throttle control that separates competent riders from fast ones.
