I have had a little pop on decel I can’t get rid of that is getting worse. I was sure it was in the jetting but couldn’t get it right no matter what. But yesterday I realized my head pipe is loose. It’s not loose because the bolts are loose it’s loose because the flange is bent in a way I can’t make the thing tight. What are my options here? Should I pull it off and straighten it out or should I just get a cheap used head pipe. I have a 04 with a cw470 kit. Hot cams, pro design pro flow. filter. Could this be my problem is this making me lean.
