Using the same method as for the 5 and 7 ports will be fine. The break in should be a litttle easier as the sport motor won't have the same extreme metal pinch as the racing motors. Do the 12 tanks as suggested in the break in method on page 78 of this forum, but be aware the needle settings will most likely be different. Just find a nice rich setting that will give the correct temps when the head is foiled with plenty of raw fuel coming out the stinger and go from there as described in the thread. Enjoy
