You will need the proper conditioning circuit to feed the rev signal to the lm2917.
You should cuple it using a cap a maybe a zener to keep the input voltage below max for the chip.
You may or may not need the diode on the ground pin.
I looked quick and did not see any circuits that would work with the ignition circuit on your bike.
