There was a guy at C.R.C a few years ago on a '82 cr480 with twin shock set up racing in the evo class
I was confused on a few levels
(1) Why was he allowed to race in the evo class, when there was a pre'85 class.
(2) Why would you want to do the above.
(3) Why do that to a perfectly good pre'85 bike.
Now I think about it I could have beaten him on a protest
