Hello,
I just bought
Acerbis Dual Road hand guards for my CrossRunner (would be better for cold temperatures in winter here).

I got a problem to install them.

I removed the screw which fix the original bar ends on both side, but I don't really understand how to remove the part which is
inside the handlebar. This metallic part seems really hard to remove.
This corresponds to the original "kit standard" on the left of this schema :

Means parts 10-12-13-14 of this :

The hand guards should then be installed with another long metallic piece that would replace this one.
I tried to put some lub' and pull it but it did not move. I don't see what could I do to remove it.
Any idea ?
I could put some pictures if you don't see what I mean.
