I completely agree as far as tuning on a dirty filter goes. I'm merely saying it ran well all through the throttle with all of those conditions as they were beforehand. I think a stock needle would help me as well. It's a 5j21 If i remember correctly. It was on 2nd down stock, and it is currently as well. 1 leaner would bring the c-clip to the top. I am going to clean the filter before I really start riding it again however.
