Do I have to change nozzles?

Hello. My moped has a sports header pipe and a throttle body, a different pinion, and I've also adjusted the jets accordingly. However, the ORI CDI is limited to 8,000 rpm.

I've now got a sports CDI and wanted to ask if I need to install a larger jet.

LG.

Look at the spark plug! (after 5 min full throttle drive)

Black: Nozzle too large
White: Nozzle too small
(Reh)brown: nozzle suitable.
