FI light on after rebuild ???

Well I've finally got my fat tire / bike rebuild bout 95% done. I was the guy with the swingarm issues and clearance. Well Kurt from Sumo-x made me a new swingarm and all is good there.

Now I have a tech ??? I removed my HPP prior to build since I had new exhaust to put on and the are Road Burners 3"duals and they both had o2 bungs. Well my previous setup was a Roadhouse Shorty with a single o2 sensor from the HPP. Got exhaust on and started bike now my FI light is flashing. It's a single steady flash. I did the ecu jumper trick and it blinks once then one long flash then three quicker flashes. I have not driven bike yet do to the weather here in Pa. it seems to be idling right and sounds good. Some decel popping under hard throttle.

Can anyone help with this problem.

If you have a code 13 front injector problem..

If you have a code 23 Engine operates normally Faulty o2 sensor heater. looks like REAR
If I read correctly from one o2 sensor to two o2 sensors.
Heaters are for quick warm up to go to closed loop for emission control.
Any mod for o2 sensor eliminator on single o2 setup?

Black/White is the +12v wire, Black/Green and Black/Yellow are the o2 heater wires from the ECM..
10-40 ohms on the heater...

SM has other codes for the o2 in regards to F/A...
My two cents worth from a 1300 owner reading SM and a schematic...

No mod for o2 eliminator. I had the HPP put on in 2002 so I don't remember what was done other then installed Road house shorty. I'm pretty sure they had to weld an o2 bung on for the HPP to be hooked up. I'm going to try a reset on the ecu today and see if that clears it.

California ECM or is the 02 strictly for the HPP?
Do you think it is a 13 or a 23 code??
HPP modifies the injector pulse duration, check the HPP-ECM connection..

Found the problem the dealer that installed the HPP cut the wire on the back of the map sensor above the throttle body. I reattached wire and all good. Just took it for a little spin runs good just not used to the fat tire and 21" front tire yet lol.

Thanks for your help though.

MAP sensor codes are 1 and 2 per ECM error codes posted at bareasschoppers.
