Just bought a 2016 new BWS in Canada. I believe this is the same as the Zuma in the states. I hear conflicting info. The dealer says no break in period is needed for the engine, but the manual says no more that 1/3 throttle to start , and slowly work your way up to full. You all know the manual info. In any case should I follow the manual or listen to the dealer. Any real engineers out there?
