Ok guys ... I have looked and cant seem to find a straight answer. I just installed exhaust (erion) and my bike seems to be running rich .. about a week later installed K&N filter .... Do I need to reset ecu ...if so how do I do it .. Some say remove + for about 5 min .... others say remove - and hold brake down 15 secs ... Is there a quick and easy way ... like with key off ... switch kill switch off and on a couple of times ... I have a 2003 f4i ... thanks guys be safe
