I had previously reported that rotating the gear shaft lever forward by one notch had led to the horizontal linkage interfering with the footrest mount….and Dexter confirmed this on his bike as well. I even purchased a generic adjustable aluminum linkage just to prove to myself that it wouldn’t work either
Finally the solution became crystal clear…..simply drill another hole in the highly robust shifter arm. I centered the hole 8 mm above the lower edge of the arm, and 7 mm back from the rear edge of the OEM hole. Drilled a pilot hole first and then upsized with a 1/4” drill bit (6.35 mm) to match the original hole.
End result after 15 minutes is that the shifter is turned up by about 7-8 degrees. Zero interference with the footrest mount with lots of clearance. If someone wants a bit more rotation, then you could potentially go a tiny bit further back than 7 mm.
Others may wish to wait for OEM or aftermarket solutions due to whatever warranty or safety regulations you have in your markets. For my personal application, there seems to be no impact on structural integrity, and the mechanical advantage of the shifter is virtually unchanged. The modification is also easily reversible by popping the linkage back into the original hole.
