Muzzy,
I'll keep an eye on your thread because I think a lot of my questions will probably get answered here as well. I have a 2007 XB12Scg that is stock other than (according to a HD/Buell receipt for work I received from the previous owner) "Performance ECM, High performance Air Filter, and Performance Spark Plugs." My ECM does not say "RACE ONLY" like others do. The guys on the forums figured my bike had received a reflash of the stock ECM to a performance map.
Anyway, if I am able to save some money over the winter, I would like to do a Drummer SS, with a K&N open airbox mod (AKA airbox delete). I will need to learn how to reflash my ECM to work with the added airflow.
