Tyrhone Posted May 13, 2014 Share Posted May 13, 2014 Hi guys, As the title says, my new piston has arrived in Guatemala (for the Blackhawk BH 125 Paramotor), and I was wondering if I need to break in the engine again just for a new piston? Better to be safe and do so? Cheers Quote Link to comment Share on other sites More sharing options...
