Rotary Engines

[Hubbs]

Dear Piston Heads

I'am making enquiries as to doe's anyone know of any manufactures that produce small capacity Rotary (Wankle) engines, no more than 50-55cc. As I am wishing to fit one to a motorbike and race next year in a amature 6hr endurance race series called Moped Mayhem ( www.mopedmayhem.com ).

Any help would be gratefully recieved
