I don't believe so. Since it is a FOUR cycle engine, Each cylinder only
fires every other revolution. It is timed so that one cylinder fires each
revolution. They alternate but since they are staggered, so is the timing.

The Harley is not made to be smooth. Both pistons connect to the same
crankpin and fire right after each other. This is part of the famous
Harley lope as the engine goes bang bang flup flup.
