@Schnidely,

I have a question about the modification of the cush drive you did on your xt660.

I ordered the same bearing as you used, the chamber I work 6 mm deeper.
The spacer can be shortened or worked on the lathe 6mm long.

Which option did you choose? If the spacer is 6 mm shorter, it does not wear in the entire bearing.

I would like to hear your reaction.

With kind regards,
Whazaah.
