is good now: .

There we see that it will be necessary to machine washers of 18 x 28 in order to perfectly center the clutch fork, and to absorb
the lateral play of the pedals on their axis:

The M8 studs that we had mounted on the back of the cover (and not the M7 due to the "RS" brake coupling assembly) are
too short. André finds other M8 "period" studs that are longer, but you have to extend their thread: and then cut them

The rear wheel brake lever has too much play on its axis 11741 (fixed on the gearbox cover). The "pendulum" clearance at its
lower end causes the release of the lug on the handbrake rack. Solution: slightly rectify the shaft and bush the lever, still a job
for Michel ( we could have thought of it earlier!). Some photos to explain the problem to Michel, before sending him the lever,
the shaft and the rack for correction .

. We wonder what can be used for this big piece of metal at the bottom of the brake lever, is it "original"?

The adjustment washers (18x28mm in different thicknesses) for the bottom bracket arrived today. Felt marking on the axle for
perfect centering of the clutch fork:

A 2.55mm thick washer should fit on the opposite side of the pedals:

We start by giving the gear lever the correct angle so that it does not interfere with the brake lever. André has determined
from various sections found in the literature that he must make an angle of about 60 °. In addition to the backward angle, we
bend it very slightly to the left ...
Heating torch, it folds very easily .... Cooling, and a layer of paint dried with a heat gun:

Final positioning of axis 11741 in the box cover (with a practical conical crushing washer found in the parts: so it is tight and
you can pin it easily):

There is no more play at the base of the brake lever, the lug fits perfectly in the rack, once again congratulations and thank
you Michel! And André is very happy: the tightened brake lever is parallel to the gear lever in neutral:
