How about some of you guys that have raced modified outboards doing some posts about the changes that are typical to prep a motor for racing. Carbs, porting, reeds, pistons, rods, ex , etc. Motor selection criteria. RPM range. Pertinent rules.<br /><br />I raced motorcycles [ 2s & 4s ] and cars most of my life but am relatively new to outboards and would just like to see what differences there are between bike 2s prep and boat 2s prep.
