Anyone have experience with these rearsets from Accu-Products?

They look nice and clean, and I like the simpler master cylinder setup.
Also, is there any other way to mount the chambers, other than by keeping the stock muffler hangar brackets? I've got Spec II racing style chambers and really don't ewant to keep the stock muffler hangars...
I'd see if nick at vintage smoke still has any for sale still.
Those rearsets offer a lot of adjustability. If that is not required, there should be cheaper and simpler options available. For pipe hangers, I'd just use 5 or 6 mm alloy sheet cut to shape and drilled. Or "skeletonized" to save a little weight and make them look better. All you really need is a hack saw, a couple of files, and a drill.
I have these on my RD400F and I couldn't be happier. Much like you I installed them for the much simpler rear master and I didn't have the stock pegs to begin with. My pipe hangers come off of the passenger footpeg mounts so I'm utilizing those.
