Check this out, same for Evos
I drilled and tapped the rocker supports and used 1/2" long 10-24 set screws on the pushrod side on my Twinkie, it worked
Next time I'm in the 111, it's getting the same thing done
Rocker Lockers, this video is obsolete click on the new video, Harley top end tick - YouTube

I dont care for the Rocker Locker idea although it probably works. Like THC said, makes dissasembly too difficult. I do like your idea of adding set screws and it makes sense. I guess you just have to make darn sure they dont work themselves out . Too bad Harley couldnt have used a little precision in the design.....

It would be so simple for them to install the shaft, drill the bolt hole and shaft together on a CNC machine, and install a bolt with a precision machined shoulder to hold the rocker box down. That amount of slop is unacceptable. Why not design a bolt with as tapered shoulder? As it was torqued down, it would tighten up the rocker shaft. There's a future patent right there. Just remember to share the royalties with me when you market it

the 'rocker locker' is actually a pretty good design, and anyone who's taken apart an evo knows how simple the procedure really is... and it does stop that ticking, if you've chased it and find it coming from the top end

I wasn't crazy about the lockers either, and I had the set screws on hand.

Wouldnt putting them on the bottom delete the purpose for easy disassembly ? I may have it pictured wrong in my head.
