On another forum (xjbikes) there is a lot of praise for using a Colotune to dial in the a/f mixture. I haven't seen any discussion of that here.
Has anyone any experience using a colotune on a HD motor? Also, what size (10, 12 or 14mm) would be needed for a 2005 1200 Sportster?
Thanks for any comments,
Bill

 

A dyno tune cant be beat,faulty plug,ignition system,fuel etc could give you baloney readings-colors.
