Well, first I let it warm 5 minutes, while stabbing throttle no more than 1/8, every now and then, next i put it in gear putted around in first and second for about 10 minutes no more than 1/4throttle, then, shut her down, cool completely in the garage, it took a touch over four hours for it to cool down completely, (used a heat gun), then fired it back up, warming again for three- four minutes, putted on front street in first second third and fourth less than 1/2 throttle, cool down again that's all i had time for that day.
Next day, repeat senerio no more than 3/4 throttle, cool down, repeat again in all 6 gears, then my first tank of gas I was a little easy on it no WOT for more than a second. Plug chopped- and plug chopped until i was satified, Then i have been beat the sh*t out of it since!
