I thought you blokes might like to see one of my modified engines. This is a hybrid ATC200X/CRF230F out to 250cc with the centre cases modified to turn the standard Honda vertical design to a horizontal configuration. I have been doing this mod for over 25 years in Australia and fit these engines into ATC70 frames.
How would one of your Grom's move with one of these babies? These engines are super reliable, run all day nice and cool and make tons of HP with either 5 or 6 speed gearboxes, electric or kick start and some have both. Up to 300cc is very doable.
