Hub, Hello Dousche Bag! Haha! Anyways, now we can get down to business after the pleasantries have been exchanged! I have a PCIII, stock exhaust, flies out, Map from PC that corresponds to stock exhaust. Also, smaller front sprocket and larger rear sprocket. My issue is when spinning the engine at about 6K RPM on the road, there is no gradual throttle response, it's like an on-off switch and very snatchy on the drive line. I don't like this, this is a smooth bike, and I am thinking about re-installing the flies, selling the PCIII on line and getting the TRE device. I also am apt to do this to improve my fuel economy as with the PCIII I get like 23 mpg.
