Yost Performance

About Yost Performance

A tinkerer since he found his dad's lawnmower always in need of improvement, Bob Yost was always about getting more power from engines. When it came time for his first Harley-Davidson, it took no time at all before new go-fast HD parts made their way onto his bike. Still not happy with aftermarket carburetors for Harley-Davidson motorcycles, Mr. Yost started making his own jets and fuel flow improvement components. Specifically, Yost found that, the finer the fuel mist he could get out of a carburetor, the better the engine ran.

This quickly led to the founding of Yost Performance, headed up by Mr. Yost himself, every component is designed to improve fuel delivery to the combustion chamber. The results are many: in addition to improved engine performance, you can expect reduce detonation when you're forced to run lesser quality fuels. Smoother engine starts first thing in the morning, especially on cold days, will become the norm. Surging and flat spots in the power band will become easier to tune out and you'll find throttle response improving at all throttle settings for a much, MUCH improving riding experience.
