Warning: The Rod Nuts one is RH tread, the other is LH tread.
That is you maybe feel it too tight.
You were tightening more.
It is designed to be able to extend or shorten the rod in place, without need to remove the upper or lower lever.

 

Well described on how to adjust shift lever height ViperTech18. But I'm glad OP has correct height he needed by adjusting " the ole fashion way". I bought new boots 2 months ago and thankfully I have a Service Manual which steered me in correct direction.

 

It didn't seem correct to start with, so maybe i've actually adjusted it back to the correct setting. I bought the bike used, so the previous owner maybe changed it.

 

The difference is big, gear changes are now crisp and precise.

 

Hard to tell for sure but it does look like it is in the correct position. There will be a dimple in the shaft and that should align with the split in the arm.

 

The reason for aligning the slit of the gearshift arm with the punch mark on the gearshift spindle is to achieve optimum leverage through the gearshift spindle which makes for smoother gear changes.

When the gearshift spindle and arm are correctly aligned adjust the gear lever height by adjusting the tie rod, noting that the lower end of the tie rod has a left hand thread (lefty loosey) and the upper end has a right hand thread (righty loosey)

 

I have a brand new 2024 Africa Twin. If I'm understanding this correctly, I shouldn't mess with the gearshift arm and gearshift spline at all? Only adjust the tie rod? Would lengthening/shortening the rod have any ill effect on shifting?

Right now, when I ride with street boots on the stock shifter position, it feels great/easy to shift. I'm looking at getting 3/4" lowered pegs. I wonder if by adding ADV/offroad boots, the shifter will remain in a good position without adjustment since the ADV boots much thicker than the street boots.

For the brake arm, that lever must be adjusted by rotating on the splines, right? I believe I would need to rotate the brake arm to be lower with the 3/4" lowered pegs. Also, I have an AltRider brake pedal enlarger that I plan to throw on, making the pedal platform even higher.

 

I checked, and the notch is lined up. So it must have been set wrong before I got it.
