There are also 70 and 85cc kits available. But these also need reprogramming of ECU.

Are you saying it's a 50cc with EFI ?
If so, I guess it would need an ECU flash.

If it's a CDI system, it might be simpler. Maybe the 150cc engine comes with a carb and peripherals like CDI/coil.

Yep, EFI with ECU. That didn't do much for the power though, and still a low compression of 86 PSI.



I agree a carb & CDI would be easier to tweak. (up to MY 2019 or 2020 it was a CDI that was easily derestriced. Alas, EU regulations (EURO 5) made an ECU and EFI a requirement.



I am looking around to see if I can find a trustworthy source for reflashing te ECU.
