Issues- Backfiring & lossing power
 

Hi All,

I have just finished getting my bike how i want it & after putting a stage 1 breather & V&H short shots i rode for about 15mile & then bike stated backfiring & losing power, speedo was going erratic for like 70mph to 30mph when under 3000rpm & fuel range went from 240km to 90km now bike does it when i take off in 1st gear, it feels as if the bike is going to die put if i clutch in & rev its ok, i done a DK coil relocation as well & i have not put in the tuner yet as still waiting for it to turn up, done a diagnostic last night & came up with this as follows : P - P0131 (FRONT OZYGEN SENSOR LOW) P0151 (REAR OXYGEN SENSOR LOW), S - NONE, SP- NONE, 6- NO RSP, Is this all happening because i don't have the tuner installed or is it because i wired the coil relocation incorrectly or have i got a leak in the new exhaust system or are the oxygen sensors bad????? PLEASE HELP. Bike is a 2011 Bob.

did you change or mess with the o2 sensors when you put the new pipes on?

I took them off to change the pipes.

You could have crossed the O2 sensors. On my 2012 the front O2 had a white connector and the back had a black connector.

Check your battery cables, make sure they are clean and tight and all ends

i never disconnected the sensors at the plugs, i only back twisted them which might have damaged the wire aye?

Yep, first thing I'd check

Since your getting codes for the sensors. It's a possibility that you damaged them by twisting the wires too much.

already checked that all clean & tight.

ill pull them & check, will revert back soon.
