Particular care was taken at fixed rev ranges (each 250rpm) from 1500 – 4000rpm for the smaller throttle openings (each of 0%, 2%, 5% & 10%) which was the final part of the process. Paul eventually got a straight line fuel mixture ratio throughout the rev range at each throttle setting and this “fuel map” was downloaded to the P.C. on the bike. The whole process probably took 4.5 hours including stripping and re-fitting the bodywork panels, fuel tanks etc on the KTM to fit the P.C. & hook up the various sensors to the laptop. Result - a really...... smooooooth ....... engine with a few more horsepower, increased torque and maximum torque now available over an extended rpm range. I also had the pleasure of seeing a true professional at work, totally at home with the equipment and software putting his years of experience on race bikes into practice onto my little KTM!
