fit the Evo is his 4-speed frame, Aad first chopped off the whole
neck and the top half of the center downtube. He used a jack and
the bending blocks of a large bending machine he borrowed from his
boss and bent the frame to clear the rear cylinder head. Because
the frametubes all have different angles it is not so easy to add
an inch as you might think.
the 2 front tubes moves the neck forward, stretching the center
downtube moves the top of that tube backwards..... The top frame
tube was too short now, so instead of welding in a short plug, Aad
removed the rearend of the toptube completely and replaced it with
a longer tube. In front of the shockmounts he had to remove small
sections because the tubes that form a triange between centertube
and shock mounts were now too long.
all the parts of the frame were spotwelded together Aad straightened
everything by aligning the neck exactly perpendicular to the swingarm
mounts, then he fully weldd all the parts. Done!
