Scim77, I am still going to try the 15/41 set up, it yields a 2.73 ratio which is close to the 16/44 which is 2.75. However I need to get the code reset. The Kawasaki service manual I purchased describes the process to reset with the three cycles but it specifies over 25 mph ,which is about 40 kph, however that is a pain in the ass. Does anyone know of a compatible OBD2 reader one can purchase? I have one for my car and truck, if the motorcycle uses industry standard OBD2 protocol then a properly wired adapter cable could be use, ever hear of such a thing?
