Took me 3 tries to completely fix my idle issue. Got my 2007 recently and it would never cold start without choke. Once it warms up the idle would never sit still at 1300. I adjusted the valves (motor sounds so perfect now). Chem dipped the carbs (everything apart but did not separate the dual carbs). Replaced the float valve and paid a lot of attention on the float seat. Adjusted the float height. Set mixture screw to stock spec. Bench sync’ed the carbs (was a little off). Replaced the petcock internal (was not closing). Now the bike starts perfect without choke and idle so smooth at 1300 rpm. I think the biggest thing I learned is that I did not know how a 250 suppose to behave when it was brand new. Now I know and in the future I can identify the irregularities much better.
