Guys,

if you have all parts of the known ChungYang (Sikk), RCMK and ZENOAH motors on your workbench and if you are not able to machine anything (you cab assemble and disassemble only), which hybrid (combination) would provide best power?

For example:
RCMK S254Evo lower end combined with ZENOAH 28.5cc top set.

RCMK bottom and Zenoah elecrical and cylinder(small or large bore) makes a tough little engine IMO.

gee no "bee house parts"

I'd use
MK SX case
Sikk + 2mm Crank
MK K30 piston
MK K30 RZ cylinder turned side ways
Zen ignition and EZ start (I'm old)
Sikk 771 carb

Randy, I am talking about mass production........

Yes Thomas I seen that ... I did create one using all production parts --

OK

MK S254 case
MK +1mm Crank
MK K30 piston
MK RZ cylinder - turned sideways
Zen ignition and EZ start
771 carb

Cheers

Randy
