air or oil cooper alternatives

[tigerjacopo]

i m looping for an alternative to my zs169fmm.. i need something strong.. 200-250cc.. of course more than 20hp…
i prefer something aricooled or at least oil cooled.. i have no space for a radiator (otherways the zongshen nc250 4v would be perfect..)

You could put a little money into that 169FMM engine with a CRF230 big bore cylinder setup and a cam to push past that 20hp barrier.
