The idle screw and the air screw adjustment is as follows > IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Set the idle speed with the idle screw. This should get you back on the road.

I agree with tombones, but you should also check your needle valve setting to lean and your going to have a lean seize,to rich and your going to go through a lot of spark plugs if you need more info on setting up your carb let me know and i'll walk you through it.

Special Requirements
  • Motocross bikes like the 1994 CR125 have a few special needs. If a motorcycle takes jumps, its orientation changes, so it has to have a carburetor sympathetic to that need. Otherwise, you may find yourself airborne with no fuel to make adjust the position of the bike by blipping the throttle or to make a smooth transition by rolling the throttle on when you land. Another consideration is that motocross bikes fall over more often the street bikes. So, they need a carburetor that can withstand a little abuse. The Keihin PJ 36 has a vertical plunger-choke, smaller and more protected than tab-chokes often found on street bikes, making less apt to get damaged if you tip the bike over, or pick up debris.

Hi, Irideayamaha it should be noted that the "AIR FUEL" mixture screw adjustment "ONLY" manages your idle and has no effect on any other circuit also any intake leaks must be repaired before the A/F adjustment procedure can be performed otherwise you will never obtain a proper idle and you will waste a lot of time chasing the impossible. The A/F mixture screw's purpose is to fine tune the fuel charge entering the combustion chamber. The following applies to both 2 and 4 stroke engines:
1. The mixture screw may be sealed at the factory with a Welch Plug please review the following video for removal.
https://www.youtube.com/watch?v=wAXcksgvDkM
2. The mixture screw manages a range of 3 complete 360-degree counterclockwise turns from the bottom/closed position.
3. The mixture screw should have a spring and o-ring for tension and sealing integrity.
4. Turn the mixture screw clockwise until it gently bottoms out, this makes the fuel charge very lean and the engine should not idle if it does then the pilot/idle jet is too big and needs to be replaced with the next size smaller.
5. Turn the mixture screw 1 and 1/2 turns counterclockwise to establish a baseline for starting the engine.
6. To fine-tune the idle circuit, adjust the mixture screw 1/4 turn in or out to achieve maximum idle RPM, wait 15 seconds between each adjustment for the idle to settle.
7. Never go past 3 full turns out this will make the fuel charge rich, foul plugs, and produce black smoke out of the exhaust, if the engine RPM keeps increasing past 3 turns the pilot/idle jet is too small and needs to be replaced with the next size larger.
7. After achieving maximum idle back out the mixture screw another 1/8 of a turn then adjust the throttle cable idle stop screw to 950-1050 RPM.
8. This procedure works great on 99% of all engines, for the 1% that demand a more robust throttle response on aftermarket monster fuel delivery systems additional tweaking outside the box may be necessary.

Honda CR125 Motocross bike throttle delay


ALWAYS have a fire extinguisher on hand when working on carburetors.
Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Now pull the top cap off the throat of the carb and remove the large slide. There will be a long needle in the center of the slide. Remove the needle and then move the clip at the top on the needle down one notch. Two notches may be required but start with one notch. Put it all back together and try it out. Moving the clip downward richens the low end fuel mix.
