Any motored Worksman bikes here?

I'm thinking about building another 80cc bike using a Worksman cruiser... wondering if the pedal crank needs to be wider than what comes stock on the bike and if anyone has mounted a pull start engine on one. Any advice?

stock engine will fit between cranks
pull starts are available but will need a wider crank (or shorter arms)
