    So if you are a motorcycle guy, you'll know that on a good portion of the new 600 and literbikes, the manufacturers are putting exhaust valve systems on their bikes, in order to flatten out the torque curve, and bump up some of the low end on their otherwise peaky 4 cylinder engines. Has anyone heard of this idea being tranferred to the peaky automobile engine world? Hondas have never been know for their stellar low end, and I am trying to gather so info. Also, if you own a newer motorcycle with an exhaust valve, and happen to have the shop manual, could you scan me a pic of the wiring schematics pertaining to the exhaust valve? that would be awesome.
