Harley Davidson Low rider 103 to 110

Dave Edgecombe owner of Dynobike fits a high compression 103 piston kit, 259 cams, 58 mm throttle bodies, SE heads and tunes it to suit. By changing exhaust systems the engine makes 110 horsepower. But then along comes a 110 piston kit. So he install that and compares the power and torque of both engine spec's. You'll be suprised what he finds. We use Aleintech "Kess V2" to read and right tune files. Winols from EVC is used to modify tune files to suit.
