This may be part of the issue right here, if it is cleaning the tank and upper part of the fuel system, then you let the bike sit and fuel evaporates from the bowls, that dirt is now sitting in your jets and bowls. I have heard this discussion on a couple of sites, and I have no idea what the truth is. I bought my '95 VFR wrecked and sitting for two years in a garage, and when I took the carbs off, they were nasty and completely clogged. But I have a '70 Cutlass that is waiting restoration that has at least 10 year old gas in it and I can put a fresh battery in it and crank it up and it runs and idles fine. I bought my '89 Wagoneer 3 years ago that sat under a pine tree for two years, had it running without a carb rebuild (I have since swapped in a 4 barrel). I have a gas station a few miles away that sells ethanol free gas, I try to use it in my motorcycles, mowers and chainsaws all the time. About half the time I use it in my Alfas, and on occasion I use it in my old Jeep. It is about 15 cents a gallon more, but I think the fuel mileage makes it about a wash. I do use a little Seafoam in all my small engines and seasonally in my Alfas and motorcycles, I don't worry about it as much in the Jeep because the intake and carb are only a little over a year old. I think the next discussion should be Zinc in the Oil to protect the valve shim caps. One thing I do know, the gas station down the street as ethonal free racing fuel and it smells good!
