Yeah, just to be clear, I'd weld a spacer to the end of the spline that sits outside the actuator housing. This leaves the machined surfaces in tact. Then, the arm operates in the same way, just in a new horizontal plane outside the exhaust.
I think this will require modifying the toe tab. Certainly you want that element directly in front of your foot for optimum safety and control. Double-check that with the arm moved outboard, will the tab still be wide enough (once cut and re-welded on its right edge) to reside in front of the peg.
If all this will work, I'll dig through my spares and see about fab'ing one up for you. (I just hope my eldest son didn't throw them away last weekend while we cleaned up the most recent teardown...)
Okay, when i move pedal 3/4" on the actuator, it moves the toe pad exact same amount 3/4" (makes since, right) so to get to its original position it needs moved 3/4".
But (there's always a but) when i move it out the pedal it is more centered on my foot. With my large feet (size 13 in the boots I normally wear for riding), the original position feels to far in. When I move it out, it feels like i have a better pedal control and more natural.
So not sure if the toe pad needs modified.
Curious, how you will modify the spacer to except the pedal? (I am confident that you have a pretty good Idea, already)
