View Full Version : might need some custom fuel maps...bike lurching after jardine exhaust

It lurches especially in first gear but does it when i'm holding the throttle steady at around 3000 rpms (not just 3000, but notice it more there). I did a tps reset after trying the race maps from the ecmspy cd but it was acting weird so I changed it back to stock and did another tps reset.

Another note I should add, I've had the spark plugs changed twice in the past 3 months because they failed on me. Thinking changing the ecm up a bit would help.

Does anyone have fuel and timing maps for a 2007 xb12 with only Jardine exhaust? I'm planning on adding a k&n filter when that gets here as well.
