Oh yes... I checked my notes and sure enough... It was the 1990's I was thinking of 
the men of steel is getting old ...
the blue forks that came in 91 where the first generation of the good kayaba usd forks. the 89-90 41mm forks were not the big hit for use in motocross or offroad . last year i had the 41mm forks in my 87 kx 250. rideable, but not happy with it... i know stories from older riders, that swapped the 88 43mm conventional forks into the 1990-bikes , instead of the 41mm usd-fork , because of better performance...
