Sprint 01 Nuetral Raised Tickover, In Gear Not?

How does it act when cold? Is the bike struggling a little when it's warm and doing this? I only ask because often weird idle behaviour is a sensor not working and the ECU assuming the engine is cold and the air temperature is very low, so ramps up the choke, which produces higher idle speeds. Could be a sensor on it's way out rather than being dead.

Could also be something around the throttle, although the behaviour in neutral throws that off.

It could be your mapping has done something else that is causing it, I assume when it was working fine you had the mapping installed then?

It might need someone with a laptop able to read any errors the ecu is reporting to pin down the problem.
