CCM R30 fitted with prototype big bore Rotax 350e engine (520cc)

My 2002 CCM R30 Supermoto, fitted with a mildly tuned big bore Rotax 350e engine,
this 350 based engine has a 6 speed gearbox and makes over 50 rwhp between 7K & 9.4K rpm.
504 cylinder head, DellOrto PHM40 carb, 805 cam, RD race valve springs, Pete Willis ported head 36mm Inlet valves, 32mm exhaust, 70.4mm stroke (std 350) x 97mm bore (std 604), compression ratio 11/1 , gearing, 35T rear sprocket, 16T front, rear tyre 150/60/17,
this experimental big bore Rotax 350 conversion resulted in a nice ridable road engine with good throttle response and plenty of top end power.
