Project started
December 2020,
See the CAD version here
| In the first pic, from top to bottom first and second printed
prototype and then the finished part. With that finished I added
the plug wires, just plain black ones as I don't want them to
stand out. Trying to make the bike as clean as possible... |
| The next challenge is the throttle cable, the bike already
has internal throttle so I drilled a hole in the bottom of the
handlebars where the throttle cable comes out, after which it
will disappear in the gap between tank and frame. That is the
only part of it that will be visible by the way. Now to connect
the throttle cable to the Linkert carb, this is a bit tricky.
The part where it needs to be mounted is directly under the motormount
and pretty imossible to reach for adjustments with the tanks mounted,
so I came up with the idea to replace the motormount nut with
a part that has little shaft in it and some balljoints.The cable
will run along the toptube and can be adjusted from under the
bubbledash. (see the screenshots of the CAD parts) |
| I started with a leftover piece of 316 stainless steel, to make
the big radius I used the CAD software to dimension 20 points
along the radius and then manually machined to these points on
my lathe, which is not CNC but does have a digital readout (DRO)
so after maybe 10 minutes I had the "ball" machined
with the 20 steps. Then in the lathe I used finer and finer grit
untill it was smooth. To be continued... |
