Hello just got a 50cc qmb139 which does not currently start so i ordered some parts. New carb pd18j, sparkplug, unrestricted cdi, high performance ignition coil and vacuum petcock.
I would like to remove all limitations set by factory or emission laws.
I checked the carb Jets and there is a 70 main and a 23 or 28 pilot. Should those be upgraded? Seems peopke in general have a bigger stock one. What is everybody running ? I have also seen a restriction in the airfilter box right before the beginning of the box. It can be removed but i read here the carb works best with it untouched.
I will put some 5g rollers as well. Do i need a 1500 spring as well?
Any limitations in the variator?
Anything more to fix.
Thx 🙏
