I can understand his response... the California Air Resources Board and EPA are really cracking down on shops, and this shop has former employees from some of the big aftermarket exhaust / tuning companies. They did say that any sort of tuning would require that the bike be off-road only and towed in and leave on a trailer. That being said, there's nothing wrong with the power the RX3 puts out. It hauls my heft around to 83.x mph (GPS speed) on a flat and level highway, and does fine at a 75 mph cruise. I think there's some power to to be hand by richening the mixture to the 12.5-13.0:1 range. But it won't be inexpensive to come by. As an old hot-rodder, I too am always curious about what other efficiencies can be gained to free up power. It looks like Zongshen did a fine job and, short of degreeing and reprofiling the cam and adjusting ignition and fuel (all expensive routes to take), Zongshen did a fine job of maximizing the power output of the RX3. As a close friend (and fellow Ford enthusiast) stated, this is the equivalent of 440 rear wheel horsepower from a 5.0 V8 normally aspirated engine. Very impressive power output for the displacement. |
