Yes the gas is that bad , you can thank Ethanol and the EPA for that crap , all it does is make you buy a gallon of gas at a exorbitant price when your only actually getting 3 quarts of gas and the rest water and Alcohol , that is why cars drip WATER out of the tailpipes , because WATER does NOT burn ! , it is what causes the jet to clog and the inside of the carb bowl to turn green , if you want to stop the clogging (at least for a few months instead of barely 1) , then get NON Ethanol gas , 91 octane or better , i personally use Non Ethanol mixed with 110 octane Sunoco Race Fuel , or when i can't get that , then i use Av Gas from the local (small private planes) Airport , either will set you back about $8 a gallon or more (for the Av Gas and Race Fuel , not the Non Ethanol Premium , its about the same cost as Premium *slightly higher*)
What i personally do , is buy 5 gallons of each , then i mix up 2.5 gallon jugs , i put 1/2 gallon of Sunoco or Av Gas , and the other 2 gallons of Non Ethanol Premium , the bikes like this mixture as they idle better and start easier , and run cooler as well , since higher octane lowers combustion chamber heat , so the engine runs more efficiently , when i race i run 1 gallon of Sunoco/Av Gas , to 1.5 of Non Ethanol Premium
The only other thing you can use is Star Tron Enzyme Fuel Treatment
