What about this SR head?
Kawasaki used front and back headmounts. It's even in the place where many 450f and never 250f have the Original mount.

very rare factory gp-parts... i still dream to have one of the 3 1990/91 worksbikes or one of this engines ...
but watch out this cylinderhead is designed for the 1990-93 parallel cooling system that the production 125 and 250īs had... the 1990/91 kx500sr is similar in some points to the 1990/91 kx250 . and i still dont know, why its never gone into production...
for sandblasters front mount, i would say : its better to lift up the mount on the frame, as high as possible to get more space to the head and using also brackets like on the rear mount...
