RCMK K30 - Zen Hybrid 30.5cc

Testing a Hellbent Racing modified RCMK K30 Cylinder on Zenoah Crankcases with a 2mm Stroker Zen Crank. Not ideal conditions for testing but motor defininatly has some potential. Torque is phenominal, max rpm 20,040k so far.

you need a big lake for 20,000 RPM !!!! Did the RCMK K30 Cylinder fit directly to the Zenoah Crankcase bolts



[qdrevenger]

@rickburnout666 Maybe for some motors, the K30 modded motor is my lowest reving motor in this pond at present. There is plenty more revs left, pipe is the hold back now. Yep straight bolt on to factory Zen Case but requires plenty of port matching.

Need a bigger pond ... let that little beast loose ......... def some potential ... nice job

@mistycreekboats Thanks Randy, yep need to go to the big pond for sure :-) Serious potential indeed.

Amazing rpm-speed motor,the 2mm crank is the staff one or like stock zen crank but 2mm stroker?

Perfect!!!!

@qdrevenger Thanx, porting is no problem for me i usually do motorbikes, and i have alredy ported and modified a 23cc Zenoah weedwacker enging to rev to around 19,000.
