How to Install Ape Hangers to Prevent Rotation

If you have installed ape hangers (or any style handlebars) and have a problem with them gradually shifting or rotating in the handlebar risers, there's any easy way to fix them (and it's not tightening the riser pinch bolts until one of them snaps off).
 
Ape Hangers  

I have ape hangers installed on both my 1993 FXSTS and my Rigid Buell Chopper, and have had problems with the bars rotating either forward or backward in the risers when I hit a large bump or have to push one of the motorcycles into the garage, etc. This happens because ape hangers exert significantly more leverage than much shorter handlbars.

An easy solution is installing a small tension pin in the handlbars and risers to prevent rotation. Mount the ape hangers in the position you want them installed, and remove both pinch bolts on one of the riser caps (The other riser cap should remain tight to keep the handlbars in position).

Carefully drill a hole the same diameter as your tension pin (I used 1/8" pins) in the center of the riser cap. Only drill the hole about as deep as 1/2 the length of the tension pin, being careful not to drill all the way through the top of the riser.

Tap the tension pin into the hole you drilled until it is fully seated. Then place the riser cap back in position, using the tension pin to mark the spot on the handlebars to drill the hole. Carefully drill a hole in the handlebars so that it aligns with the tension pin you already inserted in the riser cap.

Once the hole is drilled in the handlebars, you should be able to tap the riser cap back into place, which will force the riser pin into the hole in the handlebars. Tighten the riser pinch bolts, and then repeat the same process for the other riser.

That's it! The tension pins are completely hidden from view, but will keep the ape hangers from rotating, no matter how hard you push or pull on them.
