HaggLE,
I don't recall ever racing anyone that came from Australia specifically to race 3wheelers. Not that they didn't come over, I just don't remember any talk of such a crew or anything.
I know that Dean Sundahl WENT to Australia and raced over there for awhile.
HondaATC,
It wasn't a twin cylinder, but actually 2 CR500's joined at the crankshaft with the cranks phased 180 degrees apart. The right side engine was basically hollow other than the kick start mechanism, while the left side engine was complete.
He installed it into an almost stock Banshee frame and had some hand built pipes made for it. I never rode it, but was there when it first ran! I was later informed it ROCKED in the sand dunes and at competition hill!!!
It was amazingly not hard to start, and was quite a sleeper! The only real giveaway was the 10"+ over swingarm.
Merriman,
Yes, I know both of your Uncles! They were/are excellent ATC riders/racers! Is Callen Campers still in business?? I moved away from El Cajon a dozen years ago.
When you see them next, tell them I said "HI".
