to remove the needle quick and easy without it flying off, just put it down on a flat surface with the circlip open facing down flat and press on the needle. Clip "unlocks" without flying off.. can put a finger over the clip just to be safe :)

Excellent video, Lets add a detail! Many late model bikes have carbs with needles that only have one needle groove/position. That is to enforce running 'lean' to meet emission standards. A trick often mention to richen up that carb is to place a small washer UNDER the clip, thus RAISING the needle! It is probably fair to assume a bike with non adjustable needles is running lean, so raising by this trick is likely to give better response.

Playing with needles is the best thing you can do that is spot on indeed. I was turning my bike 03 kx250 into a woods bike and could never get the bottom end power I needed did governor mod flywheel weight played with timing on stator gnarly pipe ect ect. Then I did some research and got a few different needles necw necj ect I believe been a few years and they were from suzuki and yamaha and man what a difference before even fine tuning it instantly got beter response and grunt of the bottom as before it was not transitioning on to the pipe smooth at all and i tried alot of tuning with the kx needle. Then I got the new needle and tuned it in no more acting like a 125 where there's no power until hit the pipe it is now a great woods single track machine tuned for colorado high elevation minimal spooge and can even go down to the dessert moab from riding at 10000 feet in the high rockies and just richen air screw and raise needle 1 notch runs like a top

I've never really been concerned with what number my carbs are set to, usually just adjust them up or down a notch depending on the climate and altitude of locations be riding mostly in. Huh thanks for the information, cuz seriously I've seen people talking about #1 through #5-7 but never knew how that was untainted by the notches in what direction the starting point of #1 was or was it just something mythical someone made up lol!

It will effect idle mixture slightly. Lower the clip if you are having to turn mixture screw out to far, they can vibrate out if theres not enough spring tension on the screw. In severe cases you can shim the needle with very small thin washer under the clip.

Thank you soo much for this!!!! Ever since i rebuilt my 2006 Yamaha Blaster's engine, and then now put a new air filter on it, and fixed the airbox cover, it now runs a bit rich. I'm ok with rich because it's better a 2 stroke runs rich than lean. But it struggles to get to full rpm when revving, and also is a little slow on acceleration. When i bought the Blaster, it had no air filter on it. So, i'm thinking the last owner probably had set the needle to run richer, to acommodate for the extra airflow from the absence of an air filter. Especially because it was fast and strong af when i ran it without the air filter, and was not running too rich at all. I can't wait to properly adjust my carb!!!!

@@noctis_felis not very much. But then again, I have an Ebay air filter (which already had complaints of it being crap and restricting the engine) and on top of that, i had my airbox cover bolted on. My engine developed terrible piston slap from worn connecting rod bearings. I have to rebuild it again. That wasnt bc of the adjustment though... that was just the consequence of me geting it to run as cheap as possible, which was by just replacing top end after the last owner locked the engine up. I didnt change anything in the bottom. So the connecting rod already was badly worn, and piston had tiny bit of up and down play. Rode and rode and now abput a month ago, thats when it died. Lucky me, no catastrophic damage. I'm going to now rebuild it with wiseco. Wiseco crank, rod, and piston. Then i'll get an FMF pipe. And later i'll also get a lightweight flywheel. And new reeds. It's gonna be BUILT for real!!! My situation wasnt a normal situation, since i had cheaped out, and my engine already was getting nowwhere near enough airflow, therefore always was too rich. For you, it most certainly will help it.

@@noctis_felis Also, another tip to mention. When adjusting EITHER mixture for 2 stroke. Whether it's the idle mixture, or the high rpm mixture. DOESN'T MATTER. When adjusting those mixtures, DO NOT RUN TOO LEAN!!!! Not only will a lean mixture cause the engine to possibly not receive enough oil to lubricate it, but a lean mixture will also cause 2 strokes to experience the SCARIEST THING they do!!!! That is LEAN RUNAWAY!!! Lean runaway is when the engine starts dieseling and running on its own, REGARDLESS of the kill switch. And it screams to higher and higher rpm, till either you choke it out to shutoff, pop clutch with brakes to stall it, or it just self destructs. This especially happens when you are low on fuel. This is why I am always cautious of my fuel level, and check it constantly.

I owned an Elsinore 250 when stationed in Alaska. We would ride trails that started at sea level and climb to about 6K feet. Half way up we would have to stop and I would raise the clip two settings in order to lean the carb, otherwise the plugs would foul and the bike wouldn't idle. Of course we would have to reverse the procedure on the way back down. You are right about that clip wanting to fly off in the worse way and I always carried extra. By the way safety wire can work in a pinch to replace the clip if need be. Don't ask how I know...

I have a carbureted 2008 Crf250r. It runs great, the only think wrong with it is that it sputters in the high end of 1st gear and 2 bad gear when I steadily accelerate at a slow pace. In the rest of the gears, the sputter happened in most of the rpm ranges. There is no noticeable sputter when I quickly accelerate though. I’m not sure what this problem is, if it could be my carburetor, spark plug, or anything else. If you could help me that would be great, thankyou!

My 95 Yamaha Kodiak 400 4x4 had no power but ran okay. I bought a new carb and now it has tons of power, but boggs (as if it's hitting a rev limiter) when I'm at about half throttle. It does it in every gear. Once I get the bogg I can push past it by romping the throttle and it runs great. Any idea what's wrong?

I wrote several times but youtube seems to erase my messages. So, I have a weird case. The YZ 80 was stalled for 10 years. The carb was terrible so I bought a new one on mycarb (Amazon). The new carburetor looks impeccable. This carb only has two adjustment options. The air idle jet screw and the main idle screw. I have the slag on the cable, so the slide does fully close. The bike only runs and starts (zero throttle) with the air idle jet screw fully closed and the main idle screw fully opened. Still the idle rpm's keep to high! The weird thing is when I pull the choke out th idle rpm do drop. Any opening of the air idle jet screw even by a 1/4 turn kills the engine. The bike tends to bogg when opening the throttle fast and the bike hasn't got any power between throttle 0 and 40%. Also the bike idle rpm's rize similar like when you have no fuel and then the engine tends to shut off. As the bike was smoking a lot and the spark plug black and oily I lowered the needle to the lowest position. It did improve the performance a bit. My question is; What is wrong with this carburetor and which steps to do to make the bike run well?

I know it’s a bit late to ask but I have an issue. I have a 2006 kx250f. I’m 15 and I’m just getting into this carburetor thing but based off of videos this is what I can tell you. Both jets are clear, has a new cheap carburetor on it. The clip on the needle is in the middle. The bike idles kinda crappy and at half-3/4 throttle it holds back. Lower rpm and full throttle it drives great. I’m not sure what to adjust and don’t know if that means lean or rich. Any help would be awesome. Thanks.

@@highlandcycles alright, thanks for responding. I took it apart today and moved the clip on the needle up one. Still does it. I am going to try a larger size main jet and try moving the clip again before moving on. You think a more expensive good carburetor would fix my problem? I just don’t want to break the bank on this bike. If you think a newer carb would do the trick, do you recommend one that won’t cost an insane amount of money?

I realize this is an old post, hoping you're still active. I have a 49cc 4-stroke with a PWK type carb. I do have some experience with jet tuning, and it's running great at both idle and full throttle, but sometimes bogs a little at midrange. Would this more likely be from a lean condition, or rich? I'm thinking it's a little lean, but would love an expert opinion. Thanks a ton!

Souds like either a rich bogging or a lean bogging, if its only at full throttle it sounds like air fuel mixture is incorrect. If your happy the carbs ok, jets are not blocked etc. Try turning the air screw on the carb in (clockwise) to the richen the mixture. If its worse then its most likely a rich fuel problem. If its better then it was running too lean. Then just find your sweet spot. Average base settings is 2 turns out on most carbs. Check where yours is set before you alter the settings so you can go back to them if no better. Hope this helps 👍🏻👍🏻

Great video. I have a huge question if you have time to answer. When putting around at maybe 1/4 throttle the carb is choaking, 3/4 to WOT it runs fine, Idle it runs fine. Just the slow putting around every now and then it does that choking bog sound. Should I adjust needle or change pilot jet? Any help would be greatly appreciated!
