Im not a pro at powder coating yet. but i have been powder coating dirt bikes heads and jugs for a bike shop. they have had no problems with anything i done. After i powder coat the motor part i put it in the oven Then i turn on the oven to 400deg. with no pre heat. i leave it in there for 21min. then turn the oven off and leave it in there for another 20min. and don"t open the door till then. That is how i do it. for me thats the best i ever had anything to come out. im going to be working on Harley's too. i would like to know more about the Aluminum chemical change with the high heat. and how hot does a harley motor get when it's running. about as hot i would guess or around 300-350deg. i got a Harley and the motor on it is powder coated.
