Finally got the O2 sensor bypass part of the power up kit today (I already changed the pipe) and after dealing with the broken plastic fuel pump fitting fiasco, yep, I tried to unplug my sensor by just lifting the tank a little to get to it without disconnecting the fuel lines. (big mistake as the red one just snapped) I took it for a ride. All I can say is Its a whole different bike now. For anyone wanting to know how to fix the plastic fitting nightmare, you can check out this post on Advrider.http://www.advrider.com/forums/showpost.php?p=8664047&postcount=8777 I recommend drilling out the port to 9\16th before tapping otherwise its pretty easy,,,as long as your handy with a tap in close tolerances.
