Modified YPVS Control Box

It's been a while since I last posted a pic of a modified ypvs control box, so heres one that I just modified for Thierry(FR). This control box is for early Rd350 bikes hence the dip switches can only be positioned on the reverse side of the housing.

Reprogramming the timing of the exhausts valves is now done via the 12 dip switches on the panel. A chart with stock and suggested timings is included and I have described a few of them in previous related posts.

Velcro tape is there to keep the switches clean and from being accidentally repositioned.
