Jim; if you recall Johnnie Sanders won the '73 Paris race with a V-6. That was the one Clarence put together using old parts and actually had 2 - V-4 cranks welded together. They were150ci engines; basicly a V-4 with 2 more cylinders. I have the press release photo of Sanders winning that Ziggy pasted one of my passport photos over Sanders and labeled it super john. I don't remember what V-6 were run in '74, but the production model that was introduced in 75 was also 150ci. How about you and Clarence get together and write the inside 2-cycle race history before you both get too old to remember. Those of us that were part of the hay day of factory racing are fading away fast and without your insite, that part of boat racing history will be gone forever.
