I replaced the tank on my Kawi 250 about a month ago after the old one rusted out on the inside from neglect from the first owner. The bike sat for a few months while I found a new tank and since then it has had a hesitation at 50-60 mph at 8-9,000 rpm. I ran some seafoam initially and it helped some but it got worse after a while. So I've taken the carb off 3 times and the first time it improved slightly after cleaning it but after the second and third cleaning it has deteriorated. I just added a bottle of gumout carb and injector cleaner tonight and rode 50 miles and I've noticed an improvement. I'm looking for recommendations on what to use next to clean up the carb on my bike. Things I've done so far:
Changed out the inline fuel filter with the new tank
Put a new air cleaner on
Changed out a coil that had a damaged case
Cleaned carb 3 times including, used yamaha carb cleaner the first time around(and seafoam deep creep) and crc spray carb cleaner the second and third time
