i have a 2009 883 iron . ive had the tfi box since day one. just built a new set of long upsweep pipes with no baffles . when the bike warms up it idles real low . it sometimes hesitates and gets really hot . is there a way to raise the idle . it sounds awful when it idles. ive had many pipes and never this problem . any help would be great . thanks...peace!!!
