50 CC chinese engine tuning

Hi,

I am the owner of a MASH fifty moped. It is a fun bike, very nimble, but alas underpowered. As I have the license to ride all motorbikes (permit A in Belgium) I would like to figure out if and how the power can be increased and how the limiter can be removed. I am sure that something must be feasible with the ECU (Delphi mt05.2). Possibly some other adjustments may at least optimize the engine. As I remember Honda 50CC four stroke engines develop up to 5HP, whilst this one i listed as 2.8 HP.

The bike is a QM50-2X and the engine is model is K157FMI according tp the manual from the moped.
