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
•

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)?
