Each piston is at top dead center at least once every second rotation of the crankshaft. If you line up the flywheel marks with the crankcase split, #1 or #4 will be at topdead center.

The leftmost cylinder-nearest the flywheel-from the view of sitting on the bike is #1. The rightmost cylinder is #4. #2 and #3 are in between them.
