"Question: Why doesn't anyone make some stiffer urethane bushings for the later bars? The only way I can stiffen the front bar is to go to a 'thru the body' style bar which will add enough points to bump me a class."
Hi Wayne, I've been wondering the same thing.
When I upgraded my 84 to the later (larger) 22mm bar, I reused 2 of my 20mm bushings for the center section that clamps to the body. The 20mm bushings are from the 78-85 years.
I know it's not PU or PG, but should help take a little flex out of it.
Hope this helps
