Cool, let's see a picture with the seat and lights on there.
The front end mock up of the handlebars and controls went well last week. Progress there too is more tumbling of aluminum parts, levers, triple clamp. The gauges have now been check for light bulb condition and more hardware hi grades there too.
Using these "Special" style dished bushing washers will help squeeze the rubber bushings. A stock flat washer underneath is inferior to the custom fit here.
I'm quite sure the handlebars will feel firm using this mount style.
And, a light fresh sticky coat of Yamabond all over the bushings will help em stay firm.

The "cupped shape" washers are found on later Specials. They are the top washers. The thru hole diameter is big to slide up the bar riser shank. When using these cupped washers also on the bottom , which surrounds and squeezes the bottom rubber mount bushing edges better , an additional thin small washer under the nut which has an appropriate thru diameter for the thread major diameter is useful. That will tell you just how tight to squeeze those bushings both top and bottom together.. Clean and dry. No grease there. Perhaps sticky YamaBond even.So cupped washers help the XS handlebar bushing slop problem?
What years had the cupped washers?
That's it. See the cup shaped now bottom washer which will slide fit over the shank diameter squishes the rubber damper that one thick washer thickness more than stock. The dampers are now more rigidly held compressed just that much more. Big difference in feelI completely understand now the premise and purpose of the small washer, it's a limiter of some sort
PM me your address and I'll send ya a couple.So, who is goimg to sell me some ised cupped washers?
