Shafting happens at all levels , but still never nice to see , those bikes were supposed to be pushing out 145hp on the rear wheel , Lang Hindle from Hindle exhausts in Canada has one that he raced round about that time , and he still has that same bike , from a test review of that bike it is an absolute rocket .
Just out of curiosity , CB that Freddie Spencer raced in the States had a chromoly frame with shitty welding where visible to look like a stock frame .
Kawasaki had a few interesting things from time to time though , I bought a GPz1100 and never thought anything of it until I rode another identical bike and noticed a few differences , a stock GPz would do 85kmh in first , mine did 135kmh , mine had a ported head ,different cams and the steering head had about a degree less rake and the triple clamps were different .
