Question about Motorcycles
Hello everyone, I can not find the adjusting screw idle, which can tell me where it is, thank you
Yamaha don't make hard drives. But, I also fix motorbikes- the adjuster you are looking for is in the center of the carbs and has a knurled knob on it. (It looks like a wobbly mushroom and points towards the rear wheel and a little downwards.)

SOURCE: Yamaha TTR 250, Idling Problem
check the inlet manifold rubber has not seperated from the aluminium part of the manifold ,this is very common on the ttr 250 and will cause the exact problem you have,if it is seperated either replace it or repair it with some good quality rtv sealant avoid sillicone sealant as it is not petrol resistant and will turn to jelly.adam

Turn both the air screw and throttle screw inward until they LIGHTLY seat. Now back each one outward one and one half turns. This is the factory setting. I am going to give you a web site where you can download a free PDF factory service manual for a YZ450FR. I believe the model is a bit different but the carbs are the same.
Go to this site and you can download a free PDF service manual. The site may take up to 25 seconds to fully load the list of manuals. It is worth the wait. www.carlsalter.com/motorcycle-manuals.asp The service procedures are there in detail and a lot of diagrams and photos. Don't mess with the pilot screw unless you have to, Part #11 in the diagram.
Can I get a Very Helpful" rating out of this?

Check the screw on the side of the carb in the middle, just under the slide and screw it counter clockwise.If this has no effect I suggest you check the cable adjusters to make sure you have free play on the cable.
please leave fair comment if I have helped you

SOURCE: my yamaha ttr125L wont idle
You screw the screw all the way in until it stops, ( be Careful Don't force it closed, just turn it until it bottoms out ) then back it off 1 and a quarter to 1 and a half turns.

well first try the choke if it runs good when you pull the choke even a little then you need less air, if it runs worse then you need less air, in is less air and out is more air thats the air mixture screw.
idle screw is self explanitory start turning it if it idles up then your turning it up if it idles down then you are idling down usually in is up.
