The standard throttle lock many of us use comes with a plastic bracket that holds the throttle lock in place. To make this work with the Roadstar the plastic arm connecting the lock to the bracket runs in front of the starter/kill-switch housing. I thought it was a really ugly solution, see below
I replaced the entire plastic bracket and arm with a little aluminum piece securing the throttle lock almost invisibly to the starter/kill-switch housing. One end of the aluminum piece is screwed to the throttle lock, the other end to the start switch housing. So that requires a hole and threat in the housing, but that's easy to do. Eventually, it looks like the photo shows below:
To make this work you need to drill a hole into the starter-swith
housing at the location you can see in the photo above. You may want to open
the housing first and see for yourself where and how deep you want to drill.
In my case I chose a chrome-plated 4mm screw ("'M4") which was 10mm long ("M4
x 10"). So, a 10mm deep hole would do the job. If you drill too deep you
eventually drill into the starter switch - not a good idea. When you look
at the inside of the open housing, you'll easily see what I mean.
Once the hole is drilled you're ready to cut a thread into it. It's
an easy task since the housing is aluminum and the thread cutter ("tap" as
they call it) cuts through it like butter - just put a little bit of oil
on the tool before you start. Then carefully and under a little pressure and
back-and-forth (actually left-and-right) motion gradually cut the thread into
the housing. Since you're guided by the 3.3mm hole, it's really easy.
Now hop on the bike and test it out. See you on the road!
