Stock is a "EXACT PD26JS" CV carb that made inhouse 浙江钱江摩托股份有限公司http://www.chinamotorcycle.com/Files...I-MT201060.pdf . Nobody knows what the hell is those "jet #" !!!
Measure & ref to mainstream japanese # system (PiTA) OR fit another "primitive" slide carb that works...

Can anyone recommend a larger (maybe 30mm) carb that will work? Preferably one which is easy to fit jets for? Mikuni etc?

NO reports heard from chinese sites using bigger 30 carb on this 錢江 engine...

[Conservative scheme]
Mikuni VM22 (inlet manifold as Pulse Adrenaline that can find locally...) is a good candidate as found on stock Suzuki GSX125 (parallel imported to UK) , some Qingqi K157FMI , early YBR...

VM24 (chinese loves this old shite...) also found in early stock GS125...
