Idle problem for a kawi 250 ...06

My bike started to idle funny....
i normally start the bike with the choke on so it idle around 3000 rpm. After a min or 2 the engine warms up and i turn off the choke. But lately, when i turn the choke off the engine dies. So i have to goose the throttle to keep the engine runing however when i release the throttle the engine rpm stay hight and very slooooowly comes down.
what do you guys think ?!

sounds like you have a lean running condition. Any time the bike is slow to return to idle, its running lean. Perhaps an air leak.. Possibly carbs need to be adjusted, fuel /air mixture screws. If your bike is not fuel injected. Hope that is of some help. Patrick at Motorcycles Unlimited can take care of you.

I would suggest that if you dont know what to do, let someone else who does. If your bike is fuel injected it coul be something else. Maybe throttle potentiometer, iacv idle air control valve. im not familiar with your bike though. 06 should still be under warranty.

I run a gallon of 110 octane with the rest of 93 octane from shell, it runs very well, doesnt hurt it, and it keeps the bike from having that idling problem.

I think its gunked up carbs as well. It happened right after I filled the tank. The idle was set low, so I increased to 1200-1400 (per the manual) but the engine is still slow to return to idle. How do I clean the jets? I tried riding around to get the fuel to flush out any gunk and it did improve "slightly" but the problem still persists. I called the dealer Wild West Honda and Kawasaki, they quoted $200 and a week on the phone! Help me out here guys!

see if your carb boot is loose between the airbox and carb or between the carbs and cylinder. pretty common problem and an easy fix too.

More than likely just a little bad fuel. Buy some Siloo or other water dispersant for fuel at O'Reillys or Autozone. Mix according to the directions. It should get better.
