Japanese SEAR Autorace Engine

I saw a video where the Japanese mechanics had the top open on a Suzuki Engine Auto Race. The engine is double overhead cam, four valves per cylinder and not unit construction - normally 500cc. A 750 version might be a good replacement for a Commando engine.

She's a alittle sweetheart, and fast.

I don't understand Japanese, but I think her Granny was pretty proud of her little granddaughter whupping the big boys butts on her race bike.

I have a 73 year-old lady friend who still rides in historic road races. I never engage with her in pit-racing because back in the old days, she burned our arses. She has got a buggered back, but still won a trophy at the last meeting. It rained, so I told her she was cheating - the kids cannot handle those slippery conditions.
