Idle adjustment screw?

[NMdesertRacer]

Im a newbie to the 4 stroke world and my 450 didnt come with a manual. How do I adjust the idle? Im getting a shop manual here shortly. Thanks ?

ok it is done by hand after your moto is all warmed up....bike idles a lil hi. unscrew it to lower and screw it in to raise the idle.

Idle screw is on the right a big thumb screw with a slot in the middle...changes sometimes for diff temps and it needs to be adjusted for diff types or riding so thats why honda made it a hond screw like the Xr's...sensative

Well go figure, Mine is on the left side of the carb in the lower edge.

Thanks! I thought that was the idle adjustment screw but was'nt sure. Kinda weird having the adjuster knob mounted into rubber tubing.

Okay now watch me. "This is your left hand, this is your right hand. ?

Throttlejockey, There is a better one than that! If you hold your hands out in front of you with your fingers outstretched and your palms perpendicular to the ground the hand that forms an L with the thumb and forefinger is the left one! ?

[Throttlejockey]

Good one Fastest1.

I never heard that one before. ?

is this the crf carb less the hot start?

[bbeakley]

Nope, that's a YZF carb. They are similar though. The big black knob at the lower left is the idle adjuster on that one. The CRF has a metal thumb screw which is much harder to get to, especially when your hands are cold! It's mounted up higher and the frame and fuel lines obstruct your hands somewhat.
