Ajs moderna. Does anybody know if the 50cc 4t engine in this scooter is shared with a more popular scooter. It’s really sluggish at present and looking at options to make it get to at least 30mph in less than a mile. There’s no info available for the moderna 50cc because it’s not popular. but searching a more popular scooter with the same engine I might get some tips.
It's a 4 stroke. Not sure if it's carb or injection??????? If it's a carb model, CDi bypass for a start If it's EFi, the ECU will need either changing or re-mapping There may be a wire going to the gearbox for speed limiting, disconnect it Spacer in the variator, get rid of Aftermarket pipe
