I just added a second Flo-Commander to my ZX-11; this one collects the idle air jets to the same type of valve. As with the main system, a noticeable improvement. The common adjustment for the idle will be especially handy to satisfy the seasonal requirements. This time, the idle on my FCR-41s gets the treatment. Much smother idle and much quicker throttle snap from idle. These things are incredible.
We have run many of them on a Dyno and the most remarkable thing is the huge increase in the middle RPMs and the much smoother performance throughout. The curves look almost hand drawn, hardly a spike or disruption. My own bike picked up around 10 hp at 4000 rpm, and that is exactly how it feels. It almost feels like Iíve replaced the engine with a 170 hp electric motor operated by a hand-operated rheostat. If youíre interested in making a really huge improvement to your bikeís performance, I canít think of anything for $139.00 that even comes close.
