I tried a product called Dyna Balancing Beads in my new tires and I am amazed at how perfectly they work!! Totally eliminating all external weights and just using 1oz of beads in the front tire and 2oz's in the rear tire with perfect resullts! My local tire shop suggested them and I'm glad they did!
There is a website that explains this product in great detail and the owner was very generous with his time when I called to ask many questions about this product before I used it. The bike I tried them on is a K1200LT.
