50bmg shifter:
The shoulder of the casing was cut off with a bolt epoxied into it. ¹⁾

Below are 2 different versions of heel / toe shifters homemade by rasaine.
(the first version had the shift pegs too high in relation to the foot peg with the foot resting more on the shifter pegs than the foot peg)
So it wasn't posted on the XLF.
With the second version, the foot rests 100% on the foot peg and doesn't touch either the shifter peg.
To shift, you don't have to lift your foot at all.
You just rock down on the Toe (down shift) or Heel (up shift).
The Sportster foot pegs are wide.
So during normal riding, the foot is fully out on the foot peg.
And the shifter pegs do not interfere with any position you put your foot in.

When shifting I slide my foot to the inside of the foot peg and am actually resting partially on the chrome hinged area of the peg.

The shifter is constructed from a single piece of 6061 Aluminum, 2” wide, by ¼” thick by 36” long and cut it into 7 pieces.

• (2) at 8 ¾” for the main shift rail.
• (2) at 4 ½” for the shift rod lever.
• (3) at 2” for spacers.

I determined the correct pivot position for each piece and drilled a 15/16” hole through each of the 7 pieces.
This is the correct size hole to allow the Nylon bushing from the factory shift lever to slip into and line everything up.
The order of assembly:

• Outside spacer.
• Two Main shifter rails.
• Two shift rod levers.
• And two inside spacers.

All pieces were cut to shape and sanded smooth before assembly.
I used a Band Saw with a metal cutting blade. The soft aluminum cuts very easily.
I matched the 2 main rails and the 2 shift rod levers to each other by clamping them and sanding the edges with a bench belt sander.
Then I matched the two inside spacers to the shift rod lever the same way.
Once I was satisfied with the shape, I sandwiched the pieces together by drilling holes for five 10-24 x2” Stainless Steel bolts, inserted from the rear. (See rear view).
I only threaded the two Main shifter rails and outside spacer.
All the other pieces are slip through for the bolts, and the inside spacer is countersunk to allow the bolt heads to be flush.
Bolts are inserted with Loctite.
The bolt ends slightly stuck out from the outside spacer, I cut them off flush with a Dremel cut-off wheel.
Then I drilled Lightening holes.
Finally everything was sanded with 220 wet sand, then polished.
