Sick of trying to tune your stock carb? It's a pain in the a$$ swapping jets and adjusting needles trying to get that perfect, crisp, responsive tune. Thankfully there is Lectron. Lectron uses a special metering rod system that automatically adjusts for elevation and temperature change. You get the simplicity of a carb with the benefits of fuel injection! Lectron carbs provide higher peak horsepower, better bottom end torque, faster throttle response, better fuel efficiency, and of course you don't have to swap jets ever! Each carb is custom built specifically for YOUR bike and riding style. Just install and RIDE.
