Somethings up with that injector. Did you check the wiring from the ecu to the injector? Figger you could rule out the ecu with an oscilloscope and compare it to the front..
Wouldn't that be less of an issue on a water cooled bike?Straightjacket said:Rear cylinders allways have a higher temp on a v-twinn, they get all the heat from the front cylinder on them. On a carberated version you would jet them different to compensate.
