I let my 91-st1100 sit for over a year and sure enough it jets were plugged. I read all the suggestions and instructions from this forum and proceeded with removing the carbs. Very good instructions by the way. I replaced the jets (#40, #128), the carb boots, inspected the diaphragms. The float level seemed to be ok at around 3/8th? The jet kit came with spacers but I did not use them. I removed the PAIR, Fuel shut off vacuum switch, and by-passed the evac canister. Plugs look good and I poured seafoam directly in the carbs and in the gas. I have ran a tank of gas. The motor runs strong and pulls harder on top end but is lousily on low end. It starts and idles well but from 2k to 3k it flutters.
What can I do?
