I have a somewhat related question. Do you guys have an opinion on the best approach to breaking in a gas engine? I know you can run around the pond, but do you use a different oil? I break mine in with petroleum based oil, but race synthetic. Do you do any pre-pond bench running? I read awhile back about temperature cycling new pistons/rings on motorcycles. You were supposed to run the motor rpm up and down, shut it down, let it cool, then repeat 3-4 times before taking it on the road. Do you have an opinion on how long it takes to break-in an engine or do you just know it when you see it at the pond? One guy I know will break in a brand new motor, then swap out the ring for a new one, and take that to the race. Any thoughts or opinions?
