I guess it is time for an update on this project! In August
I brought the whole bike to Max alias Fred Flitzefuss in Germany
who will be doing some modifications to the tank; I want the
rear of the tank 1 inch narrower on each side and a reshaped
tunnel / gap between the tanks, as it annoys me that the stock
gap is so wide and uneven. I made the drawings below to explain
my plans, let's see how this will look in real steel! The left
tank will also need to be notched for the frame and rear head,
which is why I brought the whole bike instead of sending just
the tanks.Max is an extremely talented and very nice guy, check
out his work here.
I took the handlebars off so I can work on them while the bike
is away, the dragbars in the pics are just to make the bike
easier to transport.
So, getting back to those handlebars: The bike will have
a hydraulic drumbrake at the front (using the same internal
components as the hydraulic rear brake) and I did not want a
big master cylinder on my handlebars.
I came up with the idea to try to make the master cylinder
internal on the left side of the handlebar, to be operated by
twisting the left grip. The bike will have footclutch, so the
handlebars can stay nice and empty this way.
The internal hydraulic parts are taken from a 14 mm Brembo
master cylinder, everything else is made from scratch in stainless
steel, except parts 3 and 15 (2x) which are bronze for less
friction. I am using the same tiny ball bearings as in my Müller
internal throttle. There will be a tiny reservoir for the brake
fluid, which I might be able to disguise as a part of the mirror
stem. First prototype is almost ready and I have already found
some things that can be improved....
|Quite a lot of work but it is the sort of thing I enjoy doing and I have not given myself a deadline, it is fun to tinker with this in those rare hours that I am not working on customer jobs.
