Any one that has these do you think that it made your idle speed higher, to me it seems like my idle speed raised. I could be wrong but just a question
As far as the idle.....I have used them on 4 H-D's now and never noticed a raise in the idle. You may just be noticing it one, because you know you changed something and 2, it is idling better because of the added go juice so it sounds different at idle. No worries.
