i have a stupid problem that i cant figure out heres whats goin on i went out in my garage to start it the other day to ride it down the street and it wouldnt idle without the choke on i didnt think too much bout it till i tried to ride it and it was extremely lean i just figured that it had a piece of trash in the carb somewhere cause it had sat for awhile it ran perfect before it sat but i have went thru the carb and its spotless and after i got it back together it didnt change how it ran at all so i aint sure its a carb problem so if anyone has any advice on what it could be please help me

i just had a thought of what could possibly be wrong and i was wonderin if its possible that 101 vp racin fuel is oxygenated if it sat long enough with out bein in a sealed container could the molecular structure have changed to make it less flammable so the oxygenated part is more than the fuel part

bad fuel ,bad plug, do you disassemble the carb completely, and if so did you blow air threw every thing real good after spraying with carb cleaner, ? i had similar problems & tore carb down and it looked good but it will get gummed up inside so I cleaned it out and was as good as new!
