OK, I've researched this to death but still have a question. On 03 Mach1 everything keeps showing DY967 as my TPS. But with what looks like 2 brass lined holes I just don't see how it can be adjusted on a stock throttle body. I can't believe in this day and age the ECM doesn't baseline this reading at startup. Even my 08 Buell 1125R does that! What am I missing ? I'm old to cars, but new to this 03! And loving it.
