Ok been a slight change of plan with this build
I decided not to use the RCMK RZ and build up a new engine from parts and have ago at modding myself,just hope it works ok
RCMK SE crankcase modded transfer to match top end
Zen 29cc Topkit modded transfer ports and matched up the intake and exhaust ports
Lightend and relieved piston (not done by me wasnt brave enough LOL)
Big bore carb and EZ starter
All parts and machined piston thanks too Jack @ millpond models
Next job is too get it installed and setup
