i think i have an extra 700 ECU and harness )for connectors) i could send if anyone wants to invest the time..
i have the schematics as well

looking at the xt660 motor for the first time i find many components very similar to both the raptor 660 (carb bike 5 v) and the 700 efi 4 v, seem to be a mix of both ....

how does the xt660 handle higher RPM??? any Vibration in the engine?

we are currently converting a Raptor 660 bottom end to use the 700 Top end very much the same as the XT combination
