You guys are a wealth of information. The first option I tried was to clean out the Rainwater overflow tanks on both sides of the body.

I did not need to take off the wipers, only the six, six-star screws on the cowling piece front. Then the cowling was able to be lifted almost two inches on the passenger side. About one inch on the Driver's side. I taped some old vacuum cleaner hoses together reducing the size until at the end I had an 8-inch 1/2inch rod with a 45-degree connection on the end. With this, I thoroughly vacuumed both overflow tanks. Then I went looking for the drains y'all mentioned. On the passenger side, they are at the front of the tank and it is easy to get to with the wider opening. It was covered in 1/2 inch of organic matter I vacuumed out as much as I could. Then I filled the tank with hot tap water and waited. Nothing happened! I went inside and got a turkey baster and a piece of black hose that fits over the end. Held the hose as tight as I could against the drain opening and shot air into the drain line. Nothing, Next I filled the turkey baster with hot water and on the second blast, it begins to drain at the back of the tire as it should. Letting it sit for a while I went to the drivers side tank and repeated the process. With the smaller opening, it was a little more difficult. One other problem is the drain is on the outside wall of the tank and the opening was directly below a Fender Body bolt location. I shot hot water into the drain I found the drain came through the wall at the back of the electronics box mounted there. I could not reach it so I got a 1/4 inch dal-rod and massaged all I could of the draining hose and it begins to dribble. I continued to run hot water through the drains on both sides until it ran out freely. Then I added a shot of Dawn liquid soap to 15oz of hot water and ran that through both sides. I have a friend that embroiderers on this hard plastic perforated sheet you can pick up for nothing. I am going the cut out a half-moon shape and use Clear sealant to hold it over the Black fingers that are supposed to keep larger stuff out of the tanks!
