i've been doing my breakins wot with no idle in between, just wot with super rich till temps dron then lean out a turn so temps go up, wheels barely turn during the whole thing, takes about 500cc's and the motor is ready to race tune. still needs the rest of the gallon to loosen up but i have had no pinch, rod or crank issues in over 10 galolons on 4 different motors, taiwan-italy.
