Hi all i just recently picked up a used 250 ninja 2009, i did a fresh oil change on the bike around 500km ago and had no issues as well as the oil filter, this was the tank of gas that came with the bank just over half full. Now i put in fresh gas rode the bike home parked it over night and i come back in the morning to have the bike turn on and idle fine but the moment i put it into gear it wont go past 4k rpms without sputtering and trying to shut off. Same issue when in neutral 4krpms and wont go past that and sputters, any suggestions. Air filter was one of my guesses was fairly dirty so cleaned that out and now its sitting over night drying im assuming its a carb issue but was wondering if anyone else had the same issues. tia
