I got a 98 600f3 and destroyed a valve after it skipped a tooth on the timing chain. Have what I think is a “95” 600 motor but it’s got a mechanical speedo will my bike not wanna start if the speed sensor is not plugged in or what issues could I run in to with this? PC25E-2706540 is the engine vin for the one going in the bike not sure if it’s even a 95
