Heat cycled 5 tanks. Heat gun to start and wrap the head to get it to temp. Idle to 230 for 5min and shut it off...let it cool back to room temp and start over....after 5 tanks ran it fat and slow on the street a couple of tanks and then started to lean it slowly another 2 tanks.
Got to Atl.(PNB) and put a race tune to it and stood there with my mouth haning open drooling over the power I had in my hands! It now has a lil' over 2 gallons on it and it runs great.
Got a points race this weekend and then the Alabama Manufacturers race at Cullman the 1st of June...the motor will be fine! BONE STOCK.
