Back to reality. I bought some Sea Foam (at Wal-Mart) and put 4-5 ozs. in a full tank. Recently I had been turning the pilot screws out to run better. I didn't notice anything running through the treated tank, but after the second tank I pulled the plugs and checked them. They were black. I turned the screws in a 1/4 turn and it seemed to run better. Ran another 500 miles and checked the plugs again. They were very dark tan so I turned the screws in another 1/8 turn. It again seemed to run better. After a few hundred miles, I pulled the plugs and they were tan and the bike was running fantastic.
My conclusion on this is that the Sea Foam cleaned the carbs and jets that were causing me to richen the mixture to run good. The result is that I'm back where I should be and the bike is running great. I'll never let a year go by again without running a tank full (4.5 oz. for 4.5 gal.) through. Deposits and crap do build up and the stuff definitely helps.
