Author Message   Robertb1958 Posted on Monday, September 30, 2013 - 08:46 pm:        My 2008 1125r came to me with an HPe exhaust and Power Commander V tune. Well, the exhaust was too loud for the neighbors, so I got a Barker exh and EBR ECU for the Barker. Threw it together for my first track weekend Sat, pulled the HPe and PCV, swapped brains. Looking over things Sunday AM at the track, I found that the O2 sensor in front was disconnected, apparently from the PCV tune by the previous owner. So, questions: Is the front cyl O2 a factory thing? What part of the harness is the other connector on so I don't have to tear everything apart to find? A pic would ne great. Have a dyno day set later this week, should I try to fix first or wait to see dyno results? Bike ran very well at the track. Had a blast!   D_adams Posted on Monday, September 30, 2013 - 09:13 pm:        quote: Is the front cyl O2 a factory thing? Yes. It's a single wire connector, typically located above the intake snorkel.
