Here is the adapton process from the Triumph Manual:
Resetting adaptions with the motorcycle connected to an exhaust extraction
system may cause incorrect values to be set, causing poor engine running.
Always reset the adaptions with the engine disconnected from any exhaust
extraction system whilst ensuring the motorcycle is positioned in a well ventilated
1. Ensure the engine is cold.
2. WITHOUT TOUCHING THE THROTTLE, start the engine and allow it to warm up until
the cooling fan comes on.
3. Leave the engine to idle for a further 12 minutes.
The manual does go on to say that this process only adapts the idle area, off idle adaption only takes place when the bike is being ridden, every ten minutes apparently, and it writes it to the ECU on a normal shutdown ( Why its important to shut down with the key, if you use kill switch or side stand to cut motor the latest adaption doesnt get saved)
