Took the bike out and they loosened up again. Plus, the 28 year old risers had 1 bolt that was almost stripped and the others were not far behind. Installed 4 Time Serts and got busy with a hammer and punch to dimple the risers and the caps. Much better now.
Try dimpling the bars if that doesn't hold. I've always just done the bars.

Nice for a bit won't hold for long, been down this road many a time. It's the metal quality in the risers, it's soft enough it will deform again. Go to the hardware and get some sanding screen like they use for cleaning copper pipe or drywall sanding, trim to fit and they'll stay put till you're tired of bars.
I have newer Dyna bars/clamp on my Shovelhead and the bars are not dimpled (thanks Harley). Tried a variety of 'fixes' to stop the bars from rotating and finally saw a video of a guy adding galvanized hanger strap to fix his apes and sure enough that did the trick. I always have a roll of it in my garage and you only need a few inches. I never tried the copper sanding paper, but skateboard grip tape and hockey tape didn't do the trick, nor did the handy little serated wood/plastic filler strips work - they just flattened out in a few weeks and the bars would move again.
Gotta use something as thick as plumbers strap the risers are trashed, most are cheap pot metal to start with.
Mine are relatively new Harley risers - guy bought the risers and bars from Harley for his Dyna and he didn't like them rotating and the height of the apes - went immediately to T bars, like all Dyna bros nowadays. Still had the price tag on the bars - they aren't knurled.

I wonder if the risers and bars are a good match. The knurling on the bars lays right in the hollow part of the risers. It's going to be hard to prevent slipping. Is there still a gap between the risers and clamps when the bolts are tight?
