What year is your R65 ?
Are you wanting to move the pedal "outward" or rearward ?
The pivot point on the post-81 models isn't really move-able, but one *might*
be able to make fairly small changes w.r.t. rearward location. I don't know if that metal
which the pedal is made of would be satisfactory to cut and reweld if one was to try to
shorten the pedal lever - Justin would have a better idea than I. I had met one person
who had made the pedal wider (in the front) so that his foot could be pointed
more outward and still press the brake without running afoul of the carb - am
trying to recall how he did it...
This should probably be moved to the "technical" section by one of our esteemed moderators..
