You'd a poop if you watched me break in my V-spec yesterday! I do the heat cycle but a quick version. I spun it on the box til it sounded like it wanted to turn over. Knew it was too rich and turned in both needles about 6 hours each. Fired up, still rich on both, temped to 200 for about 3 minutes, shut off. Fired it up and ran to 200 for about another 3 minutes just moving at short bursts to 1/2 throttle shut off. Leaned it another hour on both, ran to 200 for about 4 minutes and off. Leaned another hour ran half a tank through it shut it off. Leaned another hour put the body on and hit the track. Granted it's not my first rodeo and I really don't recommend doing it this way unless you know what your doing but I was just giving examples of how rich those factory settings are. BTW, Duratrash probably isn't telling you to do the heat cycle method anyway. Just remember, patience is a must when it comes to a new mill.
