Default Limp mode issue

Just recently upgraded to KHROME werks outlaw 2-1 exhaust, S&S 55mm manifold, screamin eagle plugs and wires. Drove around 200km and got issue the bike not response fully throttle, while shift to all gears but in display show on N natural. No check engine.

Checked the below and found it in good condition
• ECM connection and tight
• ⁠All fuses, applied contact cleaner just in case
• ⁠throttle connector and wiring
• ⁠harness under the tank
• ⁠spark plugs and its cables
• ⁠injectors
• ⁠airflow sensor
• ⁠regulator- charging perfectly, plus wires are good
• ⁠earthing cable, near the starter and below the battery (no corrosion or lose connection)
• ⁠replaced the battery although it was fully charged
• ⁠inflated both tyres

sounds like you were in limp mode and it should be a code.

About not responding to full throttle.... You made a pretty big change in airflow with a new exhaust AND bigger manifold.... Did you retune the bike?
Was it a piggyback tuner, flash tuner canned map, or a dyno tune?

If you retuned with an appropriate tune, then check the intake manifold install for leaks at the seals and/or for bad or missing vacuum hose attachments.


About the neutral light always on..... Did you install the exhaust system yourself? It's possible you messed up the neutral switch connector/wires in the process. The neutral switch is on top of the transmission. I would start looking there.

Good luck and keep us informed of your progress....

Code B2218H = "Neutral" switch shorted...nay chance you messed with the handlebars/grips? Or...did you melt wiring to the switch b/c of exhaust install (result)?
