Now there is a trip down memory lane! I had a 400-4 too...truthfully, I did a great job of ruining it by trying to turn it into a "cafe racer"... Thanks for the pic!
Yea, when I sold that bike it had an Ocolet fairing and a set straight bars that lowered the grips like 2 to 3 inches. I have very fond memories of that bike.
I had a 400-four as well. It was bright yellow and was the first bike that I bought brand new - I was 17 years old. I loved the 4 into 1 exhaust. I made sure that the headers were always sparkling. My buddy had the red one. If I remember correctly, it red-lined at 10,000 rpm. Smooth and quick. Thanks for reviving the memory!
