A while ago we started on the hydraulic clutch conversion;
on a stock style kickstartcover we removed the hole for the
clutch arm and drilled a center hole where the clutch pushrod
is located. We found a small suitable master cylinder and made
a test setup to determine what diameter we would need for the
piston in the cover. We want the piston to move about 2 mm when
operating the master cylinder.
We tucked away the master cylinder
behind the primary and then turned our attention on the kickstarter
cover again. The idea is to weld in a bar of alumium, so that
the whole thing can be held in a lathe for machining, then cut
off the extra material when all machining is done.
The aluminium bar was machined 0.05 mm oversized, after heating
the cover it dropped right in and after cooling was firmly in
place. The whole cover was heated again before welding, next
time we will do the machining and finishing of the cover.
