akward idle

[KAlger]

After I start up my 05 250ex and it gets up to operating temp, the idle drastically increases. Can anybody suggest a fix? maybe a pilot jet or something?? Thanks

on one of my friends bikes once the bike is warm the bike gets substantilly louder and he changes the idle screw on the carb back down

I dont really understand the question. The bike will idle lower once warm.

if the idle is to the point where it sounds like its skipping and barely holding its idle, then the idle screw needs to be adjusted.

if the idle has a lope, your fuel screw needs to be adjusted. with a stock cam the idle should be very smooth at idle.

if the idle is low one second and high the next, you should check for air leaks.

its as if its running with the choke on.

after it you start it up and run in for 2 minutes, you come to a stop and the bike increases revs noticibly. and like it was mentioned early, we can back out the idle but that doesn't seem like the appropriate fix.

Make sure your throttle cable and choke cable are adjusted properly first. If that isn't the problem try adjusting the fuel screw (small brass screw just in front of the carb bowl that points straight down). I would start at about 1.5-2 turns out from lightly seated and adjust for the highest idle possible and then back off the screw slightly(about 1/8- 1/4 turn). **Make sure you get the engine up to full operating temp before adjusting the fuel screw.

Then you can adjust for proper idle rpm's

sounds good, thanks for everyone for giving good suggestions!
