The crank turns twice for every revolution of the cams.
Some bikes have the ignitions on the end of the crank, others up in the cam.

The cam rotates once per engine revolution, but the tach drive pinion is much smaller than the drive gear on the cam, so, Id have to say its not 1:1
Im pretty sure its 4:1. I have my head apart, I will check when I put my cam back in this week.

If you want to be 100% sure, you can disconnect the cable turn the engine over manually one full revolution and count how many times the cable turns.
