So my buddys bike is in my garage . His problem was it would start but not idle even when warmed up .. we took his carbs cleaned the hell out of them and assembled everything again now the bike runs and will idle on its own without the choke on . But its not very smooth. Sorry the bike is a 2001 katana 600. So my question is will carb syncing help out with getting to run smoother ? Does anyone have the tool I could borrow ? I'm in stoughton ma thanks in advance for any imput
