Both outer plates have been cut down and drilled. With the pedals and pegs in place, I sat on the bike and was relieved to find my feet in a more-than-okay position.
I cut the inside mounting plates to match the shape of the outers and made three more spacers for the forward mounts. No photos of that, but it’s no great loss—that’s pretty mundane stuff.
I’m currently making the rear spacers out of 1.5″ dia. alloy. These will be attached to the outer plate via the footpeg mounting stud, and to the inner plate with hree M5 screws at 120 degrees around the periphery. This will allow me to orient the footpegs and the inner bolt holes independently. I realized as I was boring out the recess for the nuts that the studs on the YZF600R footpegs are two different lengths.
The shorter stud is on the shifter side. And yes, the “shifter side” is the left, dammit. I had a BSA B50 and never got totally comfortable with the right-hand shift. I am planning to make the shift setup a crossover, so any Bultaco motor will fit, including pre-’75 RH shift crankcases. For those unfamiliar with Bultacos’ idiosyncrasies, the later ones do have a shift shaft that exits the cases on both sides, but since the engine was never designed for it, the left side ends up directly behind the drive chain. (Big help, Irving!) That alone complicates any sort of rearset arrangement, so I might as well make any year engine fit.
