I went into the cyclexchange.net site and what a blast! This begs the question why didn't Honda think of this? To bad they don't make them for 500 fours. I am not into racing, just some way to cut down on the complication. I have thought of making my own conversion ,but I do not have that kind of time,getting old and tired. It seems to me that done right,this would give just as much power or more. Like I said ,if you want a lot of power go supercharger! There are other ways to get more power out of an engine,one being a chamber in the intake.Look at most of the new autos that are being made and notice the rather long intake setup[cuts down on spitback thus more fuel /air into the engine]. Tuned exhaust headers give a boost but only at a certain rpm where it is the best boost. What do you think of the bypass idea? Don't some motorcycles have that setup? A penny for your thoughts out there. Come to think of it,if one wants REAL getup and go why not go for jato power[jet assisted takeoff] ,works on airplanes! Maybe it has already been tried. Now that would give you real take-off like a shotgun performance! Good to get rid of tail gaters to!
