I had foam in between all the wood on my first KR. It was covered with one layer of glass from the firewall to just aft of the seat back then it had automotive upholstry on the glass with contact cement. It really made a big difference in the noise and probably didn't add more than 3 or 4 pounds. It also gives you a nice flat surface to put the upholstry on. I would highly recommend doing it.
