So, figured I would finally make a post since im stuck, been coming here a long time lurking and pretty much finding all I need to with prev. threads, however now I need some advice.
03 Xb9s 20k Miles Race exhaust and kn filter /race tune BUEGB, I will list what I did this year to it since its when it all started going down hill for me.
Jan 17 rear cyl temp sensor dies fan refuses to kick on but runs when jumped. fixed new sensor.
March starts throwing 02 sensor running lean/inactive. cali bike originally with smog removed the evap line to the intake had a whole in fixed blocked it
April again i start getting consistent code 13 this time its 02 inactive. replaced 02 with ac delco, 1 week same thing, replaced with bosch , same thing OEM replacement is fitted nothing changes...
June notice my head light is out, (all this time ive been lurking around here trying to put info together) convinced myself its either a ground or voltage regulator since my was looking crispy when I removed it for inspection. replaced the voltage regulator with Ricks which is not a OEM fit btw.
July still throwing 02 inactive/changed intake seals because of suspected leak and also sparkplugs and wires. Data logged new tune runs infinitely better and no decel popping.
August issue persists but is random always at highway speeds on cruise throttle being held steady, CEL flashes but keeps no code , doesnt stay on permanently, when It stops flashing and I get a solid CEL reads 02 inactive.
FINIALLY CHECKED CLEANED and re did all grounds except for headlight assembly. No more 02 inactive. (got tired of messing with it as you can see from my post I have two other bikes and one is a project bobber, the other being my gsxr.<-- i rode that since i got fed up but I keep coming back to the xb dammit.)
Sept Oct getting tired of messing with it, when I took it for a long test ride 100miles ish 2hr ish mixed but mostly highway a CEL flicker but it went away almost instantly i pulled to a gas station and ran the code. code 14 engine temp sensor too low/broken wire.
Besides the 100mile test ride when it gave code14 to me with in the first 5 miles , after that i never saw the cel flash and the rest of the test went smooth with no issues, coming home from work one day it flashes like I said almost 5min into the ride not even 5 miles. I get home check code14,
Important to note fan works when the bikes is running and when I stop.
okay seriously I love this bike if my solid block of text isnt proof.:mad-new::mad-new::mad-new:
Could it be a ground? Have I missed something or could the temp sensor fail since it was the first thing replaced and I was troubleshooting test riding on and off all those months? I will do several more rides to and from work 20 25min rides to see if it is a consistent throw,
I will go for another test ride and update see if its a pattern from cold starts/bike being left out overnight ect.
Sorry for the long block of text I tried to be as detailed/ as possible with pattern of issues and also keeping it sweet and to the point. Looking for help thanks guys.

) to see if theres an anomaly in the circuit. It will show you a wiring issue (if there is one) and allow you to narrow it down using a wiring diagram much easier than ripping the bike apart and splitting open every harness junction.
