Sparkplug Analysis
Am trying to embed a photo of 2007 Ultra sparkplug with 4000mi total miles (3000 with bike at stock and 1000 after 0903 recall/upgrade). If picture is attached can I get comments on apparent fuel mix, etc.

RE: Sparkplug Analysis
Thanks for imputs. The plugs appeared good to me but the 07 Ultra is my first experience with EFI so I wanted additional opinions. Bike runs great! I bought it at the end of Sept. and it has been cool so I can't comment on engine heat but I was a little concerned with the factory-set lean fuel mixture discussed in this forum.
Thanks again, Bob

RE: Sparkplug Analysis
At last check milage has been a running around 41mpg. I really haven't noticed any difference in mpg after the 0903 download. As I say the bike has been running great. In my opinion the download did appear to provide a little more response/power in the lower rpms (2000-2300 range).
