Gday, Went for a ride on my bike this morn i notied it was idling high when i pulled up at intersections then would drop back slowly im having a guess that it is the idle up motor on the efi. when i pulled into the shed at home the ck engine light came on for a few seconds then went out. i turned bike off then started it again i cranked the bike over after it started the light came on for a few seconds then went out. can some one give me a run down on how the light works will it flash out codes when key is 1st turned on or do i have to go into it more its a 2008 sportster thats preety well stock apart from a set of se2 slip ons. i have a work shop mannel coming but its on its way from the usa so i cant read up on it much (i know its under warrety but im 200km from dealer n dont have time at moment to take it to them) any help would be great
