Had to take my shoes off to do the computation, but what I got out of your post is, you race with a $9000.00 Honda motor. Of that $9000.00 initial investment you can expect to reuse about $6000.00 in reusable parts from your original investment on your next engine. How many races or seasons do you expect to get out of your Honda?
Taking everything into consideration sounds like you are doing pretty good.

PS Do you guys also race backwards?
