bike is hesitating like its starving for fuel around 5-6k. everything feels very smooth but it just kinda falls on its face when rolling on the throttle pretty hard. i was told the bike had been sitting for quite some time. it fired right up and idled like a sewing machine so i didnt drain every drop of fuel when i got it because it was practically empty. but after filling up (the first and only time) it started doing this. i was just wondering if a FI cleaner could solve the problem. the bike is completely stock with 4500 miles.
