First time I went was in 76, on my green 73 750. that was the year I got it.
Went quite a few times between 76 and 87.
Man there used to be a lot of quick singlecams running around back then gobs of 836's..900's.. a few Cobra motors.. Used to be some wild bikes I remember a CBX around 81 that had about a 6 inch slick on it and would sometimes be losing traction at 80 mph in second or third gear..!!
Ah the good old days..
