To make room for a project bike, the Duke 390 has to go, sadly.
Therefore, I have removed all the goodies, and they're now up for sale.
One of the problems with the little Duke is hesitant, jerky slow speed running due to a lean air/fuel mixture to comply with ever-stringent anti-pollution regulations.
To overcome this, and to provide a bit more get-up-and-go with better throttle pick-up, Coober developed this piggy-back ECU in conjunction with KTM.

o Throttle position sensor.
o Fuel injection.
o Ignition curve.
o Crankshaft position sensor.
