I work at Lectron, that should be a simple fix. The bogging is from the metering rod being too lean. Either the previous owner messed with it too much or the motor has an air leak somewhere (or bad reeds). Try setting the idle screw to about 2 turns from all the way in and seeing where it idles. It will probably be very high. Then turn the rod clockwise until it idles normally. Keep in mind that the flat side of the metering rod must face the engine side of the carb. You make adjustments by threading it into the slide, then reorient it by pushing it into the slide and turning. If that doesn’t work, the bike definitely has an air leak. Good luck and definitely reach out to lectron if you need more help!
And that would be correct if it was a real bog. Is it though? It really sounds like a sputtering sound to me. Listen again. Not trying to start trouble, my ears just tell me the other way.
@@Realryancurry it’s 100% a lean bog. It gets worse as he gives it more throttle, sounds hollow, and the engine only recovers if he lets off. BeRAD has a good video where he purposely tunes a carb too rich and too lean that is worth watching
I have the Lectron pro on my 2024 yz250x and I have called and been talking to nick and hunter and I can’t get a straight answer out of them on how to get it running properly
Had the same issue with my sons rm85. Pulled the carb, cleaned all the crud out and she was good to go. Yay for a new bike project! I just picked up an 84 200x atc myself
I had the same exact problem with my first 85. It was a 2004 cr 85 that would not run right at all. Put 3 different carburetors and stator and whole new engine and it didn’t run right.
Lectrons are great carbs IF you know what you are doing with them. Based upon the other issues you have found, I would not be surprised if the metering rod length is all whacked out. Contact Lectron and they will give you the starting length for the rod. After that, check the float heights as someone else has already stated, getting the carb back to baseline will be the first step.
I always have to laugh when I imagine your girlfriend doing some housework or especially speaking with someone on her phone and at once she hears a fricking YZ 250 start and rev in the garage🤣 Amazing Videos Kincade!
I ended up picking up a 1995 yz125 a couple weeks ago. The seller had done a top end in 2018 and supposedly has put maybe 20 hours on it. It had some weird hot start problems, so I started to take things apart to look for the problem. Turns out there's scoring on the piston and it probable needs another top end. Super nervous to start working on it as this is my first time fully wrenching on a bike, but your videos help with the confidence quite a bit. Cheers kincade!
I did my first top end on my 19 TE150 this year. Ain’t nothing to it. Just follow the manual and take your time. It’s awesome how simple yet fun these bikes are
I have a bike that's been problems from the beginning hasn't started yet. Weird problems too just hard shit. Finally getting it back together, thought it was just a top end like the guy said but it was full of rust and mud. Long story short I was scared of gaskets at the start and now the bottom end is about to get put back together. So it's a hole you'll dig but you're learning so much from one engine it's worth it
great work! one thing i never saw nor heard you mention was fuel. i always dump the fuel out on any machine i get, cle3an the carb, note the jetting and put in new fuel. i always run 32:1 maxima K2 with LL100 fuel. works 100% every time :) repalce the lectron. very common with those. also check the reeds.
You’ve gained 40k followers since I subscribed and let me tell yah you deserve every single one of your followers , I’ve been a motorcycle mechanic for over 10 years now and you’ve taught me some tricks here and there , keep up the good work man 👌🏽
.. Awesome buy and fix!! I have many leftover parts from an '01 yz250 that I parted out .. carb, right outer case, other items. If you need anything give a shout, I might have it. Lectrons are great carbs.. I have them on my KTM 200 and CR 500. Bike is lean.. Lectron should have a starting measurement if you call them.. start there then make adjustments ...
My guy KP likes to live dangerous. After closer look that crank takes up so much room it would have to fall perfectly but we all know that’s how’s she goes. Can’t wait till you fix the bog 🙏
Fun watching the build, got a 95 yz250 I’m working on rn. Waiting to send the cylinder out so it can be honed and sleeved cus I got 2 small cracks on the wall
I always lean the bike over before first kick to a see a few drops of fuel comming out of the tubes and then it starts second kick always but if i dont i also have to kick for 5-10times not sure what thats about but try it and see it works!
on my yz125 i dumped it hard in water and filled it with water. after clearing it of all water and changed the air filter i didnt screw on the air filter when i went to kick it over and it had a fuck ton of air flow. it made the same sound this 250 made. only difference i can think of was mine didnt bog down that hard in neutral only when i tried to ride it. (air filter was basically half way off) so maybe by chance its getting way to much airflow and is just killing thwe bike when you rev it.
I dont know if this helps but I have an 04 yz125 with a lectron and from time to time it will bog out when given throttle from idle. So I’m interested to see what the problem is and how you resolve it. Love your videos and keep up the good content 🤙
you should get a new clevis for the rear brake it'll get rid of alot of slop there I've done the old bolt and nut method and it works but having a new clevis is the way to go
If cleaning the carb doesn't work I would check the transmission oil and if there is less oil than you put in, your clutch side crank seal could be bad.
New plastic. The Batman school of art plastic did not hit the YZ250 2-stroke until 2015. That is why I cut off all the batman arrow heads and points, removed the transformer cartoon front fender, replaced with a 2014 front fender (yes I did have to mill in the proper hole locations), so my bike does not look like some abstract art (function-less and no meaning), from a "Speed Racer" cartoon (Late 60's/early 70's cartoon). The change to the ugly plastic for the YZ 2-strokes is in 2015. You guys should wear a cape, and complete the artistic look into nothing related to function. :)
I also could not stand my 2019 YZ 250 front number plate, that looks like the arm shield for the God Of Thor. So I went a bit silly myself, because it made me laugh. Back in my HS days, we had a machine shop in HS, (that was considered the thing for dumb kids,---as we created the factories that got those losers out of poverty too). Yes, I personally know the guy making all the Indian Motorcycle fenders and tanks in Michigan, (with other customers stuff). He did not study arts and crafts, race relations or gender studies in school. But he would be one heck of a good teacher---not found today. They never hired 35 people and got them out of poverty. We did that with our freedom---what is left iof it (recreational industries mostly, but still constrained and dictated by the state,--like the 4-stroke forced on the industry by the EPA. Want to know aht leads us to our dictatorship> The loss of our liberty to think and produce in the free enterprise that free people started,--before our government gave it to communism in china. To bad us producers followed. But "force" (economic governm,ent force here), will do that.
On yea. I forgot about the number plate replacement. it took me quite some time to figure out how to mount it, (I have a little machine shop, made my own mounts from billet aluminum.). I could not find a 1979-ish YZ font number plate that I liked that looked authentic for that time. And i did not have a good piece of plastic to make my own. I put a 175 gram Frisbee on the triples, and started laughing. So I mounted it (finally. More time into it than the engine and suspension). I even made it "quick release" with no tools needed,--in case anybody needs a Frisbee during a trail break. :) My YZ is now ----Perfect, from engine power delivery (I modify 2-stroke engines for a living), to bike lowering, and plastic thsat did not come from the Batman school of art. :) Wanna try to beat me on a flat corner on a modern bike? You have to be a better rider to do that to match me, and lot better rider to do better.
Dude, it's always cool to see a new project. You should transplant the engine into a 2018 or newer yz250f frame. Im not sure why yamaha doesn't already build this combination. I just think it would be way cool.
Because it is not needed. pay as much as you want,--for things that are not needed on a dirt bike. Cost keeps people from riding, and buying stuff. It is a dirt bike that a kid used to be able to buy---or the record books would be much different in the 70's and 80's, which would make the rest of you even slower that the amateur racers today. :). Big jumps aside, on these smooth tracks, you can be as fast on a 30 year old bike if they pulled like a modern formula 1 4-stroke that nobody can afford to actually grow the sport. I bet you don't pay for your bikes.
The 2-stoke YZ250 is the best selling bike on the planet today, and for the last decades, and you have no idea why. We are going broke son,---and it was called "Progress"in our schools today. Wanna bet, these are the best days of your life?
Modern YZF frames wouldn’t offer the space for a 2 stroke header out the front due to the reverse head design. The frame tube goes much farther down than a 2 stroke frame
I’ve got a question: when you have time could you go through the most used tools or some of the tools that have saved you from time and time. Looking at starting to do this for a hobby as I enjoy a project as well.
I think I would like the steel frame better than my 2019 YZ 2-stroke aluminum frame. The aluminum frme transmits more engine vibration to the hands, and I have a bit of a hand numbing problem in my 60 year old age. I have never seen my levers bounce so much from the engine idling with no fingers on the levers.
Plus, the new bikes are too tall. MXA would have destroyed it in the 80's and 90's, and it is taller than the KTM's it complained about back then. Need a berm to turn well? :)
kincade what could be wrong with my Sherco Sef-r 250? i just changed the shift return spring and after that the gears didn't go in easily. I just thought it might be because it didn't have oil in it, but after i putted the oil in and shifted in to second it wouldn't shift lower or higher. I would assume that something is wrong with the shift shaft or with my wrenching.
I’m in need of help my dirt bike 2019 KX 250f front break is working and will stop me but it’s super easy to pull it to it goes right to the bar we have bleed them a lot
On that old of a bike, or even if ridden a lot in 5 years, we often think the cylinder plating is still good. 5 years of a lot of summer riding, (5 piston and ring changes for myself), is a about the max for the best plating. And not all bikes have the best plating.
I know that "vintage" guy on YT, would not replace every beating in the einge on the old bikes, and check the crank rod play for a very possible crank rebuild, (about 3-4 years of a lot of use). I would.
12:02 That plating has about 3 good years of riding on it. (4 days a week in my estimation), that I can see from that angle, and i still see cross hatch. Got lucky. :)
Sounds good, but very ridh. The YZ's are very rich stock. MXA says it is god, but i am on the top clip on the needle. A Lectron carb runs rich? (I never tied one, but don't need one for my pretty constant air quality with a lack of elevation change and the knowledge to jet a Carb well. When it is jetted well--there is very little smoke, (pretty much just for start up, and does not last long), and no oil mess around the pipe. I say you may be missing 2 hp.
You had the choke on on the bit I saw,---at the time. But still sounds like a fuel delivery problem as the slide opens, (bogging). If it were going rich, (and bog), it would smoke more there. Need 3 things to run. Good spark at the right time, enough compression, and the fuel/air mixed at a good ratio at any rpm. You have it at a carb problem for sure.
Question, I have an 03 yz250 that was fully rebuild top to bottom by past owner. Went on a few rides and everything was mint. Got the carb redone for my mountain riding. Went back out and started to notice that every time I would hit washouts or just huge dips the bike will bog down until I get back on flat ground. Has all the power on flat road but once it hits bumps it bogs down Hella. Thinking it was the carb, I got it done about 3 to 4 more times with different float hight and different jets but still same issue. Do you think maybe electrical? Something that doesn't like bumps/getting hit around... please help
That’s an interesting one… does sound electrical. I had an issue like that on a DRZ400. On bumps, the kickstand sensor would engage and momentarily try to kill the bike. YZs don’t have anything like that, but I’d probably be checking the kill switch.
I got a 1998 yz400f the other day. Can anyone give me any recommendations for this? When I kick, doing my slow kicks to get it in tdc, occasionally it will stick all the way down. If I give it a little tap it springs right back up. I barely have to do anything to un stick it. Seems like maybe just a worn spring?
Check the needle. Or the jetting. Since its not a original pipe and the previous owner wasent the brightest mechanic and defenetly did something wrong to the needle/jetting.
BeRAD has a video on how to tune the lectron carb: ua-cam.com/video/Pz4JF-NSHho/v-deo.htmlsi=lXKCeLkukBY2Ubc7 Love the bike, mines a 99, wish id have gotten a slightly newer one for the updated plastics, but she’s nice regardless. Mine also has a lectron, his video helped me out huge.
I am not a fan of those carbs. They're too finicky in my opinion. Also, you never know if the previous owner messed with the card so I would just take it out to a full clean and break down and make sure everything is working right. Honestly if it was me, I would put in a keihin carburetor and move on with my life knowing that I'd be able to sleep peacefully at night. 🤣🤣🤣
If that guy you bought it from put on the carb,---it is messed up. :) Thank your lucky stars that he did not start it with that clutch set up. Gear Teeth would be missing, but at least the low oil volume would not have carried the teeth fragments into the rest of the tyranny. :)
I don’t think that is a “bog”, it’s blubbering/ sputtering (to rich). Or that’s what it sounds like to me. I saw Lectron guys comment, I disagree in my interpretation of that sound
I work at Lectron, that should be a simple fix. The bogging is from the metering rod being too lean. Either the previous owner messed with it too much or the motor has an air leak somewhere (or bad reeds). Try setting the idle screw to about 2 turns from all the way in and seeing where it idles. It will probably be very high. Then turn the rod clockwise until it idles normally. Keep in mind that the flat side of the metering rod must face the engine side of the carb.

KING OF PROJECT BIKE VIDEOS🔥
Great video. Is there any way that you can do a video on overhauling the rear brake master cylinder?
10:31 If you look at the lever to clevis bolt, there's a ton of slop. Might be to wrong bolt.
I always lean the bike over before first kick to a see a few drops of fuel comming out of the tubes and then it starts second kick always but if i dont i also have to kick for 5-10times not sure what thats about but try it and see it works!

Let’s gooooo! Seems like a decent pick up. Def crusty but has some potential. Love your project videos!!!
I love your videos man!!! Keep us the good work
love these type of vids ... more please
Video 6 of trying to convince Kincade to do a subscriber rebuild 😂😂 KTM 125sx 🎉🎉🎉 congrats on the new bike bro!

Please build it 🙏 … love your videos keep up the good work
you should get a new clevis for the rear brake it'll get rid of alot of slop there I've done the old bolt and nut method and it works but having a new clevis is the way to go
That bogging was the same thing happening to my bike end up being a faulty plug, I adjusted the carburetter pin to the top groove was running too rich
So motion pro makes a Double ended wrench that’s made for torquing cylinder base nuts
If cleaning the carb doesn't work I would check the transmission oil and if there is less oil than you put in, your clutch side crank seal could be bad.
YAY new project bike!!
I really like the project videos
the bogging even my kx65 does its been rebuilt about 40 hours ago it only does it for me when cold
Unreal video. Liked and followed keep up this kinda content 🔥
By the color of your tool chest behind you that bike looks like it was painted in your garage.
thats probably a 2001 yz250 restyled to a 02 plus.different kickstarter and the rear brake reservoir is still on the frame mounted.
02 had the reservoir on the frame 03 is when it changed to the master. 01 also had a steel subframe. agree that is has a 01 kicker on it though.

4:30 you son of a gun
Got ‘em 😂
i have the same bogging problem on my gas gas trial 280,i wanna know how you’re gonna resolve that😭
I had that bog happen with low air flow. Do you think your filter might be clogged or the bike is just running way to rich.
Yo! I plan to go into nursing too next year when i go to college! Can you ask him by chance what its like and biggest thing he had an issue with???

You had the choke on on the bit I saw,---at the time. But still sounds like a fuel delivery problem as the slide opens, (bogging). If it were going rich, (and bog), it would smoke more there. Need 3 things to run. Good spark at the right time, enough compression, and the fuel/air mixed at a good ratio at any rpm. You have it at a carb problem for sure.
" If it were going rich, (and bog), it would smoke more there.", and it would not die so quickly as a fuel shortage will as the slide opens.
Was so close to dropping that circlip put a rag down there
my yz125 used to do the same thing. it was the power valve
it would get super clogged after abt an hour of riding
Ditch that lectron...pwk for the win
SmartCarb for the win 👌
In the world of UA-cam, how is watching a video on exactly how to fix it, not at the top of most people’s list when working on these things.
sounds like it runs too lean when you start giving it trottle.
ive never had my hands on a lectron but maybe try moving the needle up
That’s a rich bog a lean bog would cut out like he shut the motor off
I had crank seals cause a bog like that
Let's be real, we never stop doing questionable things with bikes over the years.
Had the same problem with my yz125 with a lectron tried to contact them but they left me hanging and the bike run like crap don’t know what to do
Carb clean
Question, I have an 03 yz250 that was fully rebuild top to bottom by past owner. Went on a few rides and everything was mint. Got the carb redone for my mountain riding. Went back out and started to notice that every time I would hit washouts or just huge dips the bike will bog down until I get back on flat ground. Has all the power on flat road but once it hits bumps it bogs down Hella. Thinking it was the carb, I got it done about 3 to 4 more times with different float hight and different jets but still same issue. Do you think maybe electrical? Something that doesn't like bumps/getting hit around... please help
That’s an interesting one… does sound electrical. I had an issue like that on a DRZ400. On bumps, the kickstand sensor would engage and momentarily try to kill the bike. YZs don’t have anything like that, but I’d probably be checking the kill switch.
i hat that choking problem on my apn 6
That sounds like a lean bog so maybe a carb issue?
Kincade, 2002? Kicker looks like an 01 just curious I own an 02
I’ve had 2 comments on this now. Ran the VIN, says ‘02. Not sure if that’s incorrect or someone maybe put the wrong kicker on it?
I got a 1998 yz400f the other day. Can anyone give me any recommendations for this? When I kick, doing my slow kicks to get it in tdc, occasionally it will stick all the way down. If I give it a little tap it springs right back up. I barely have to do anything to un stick it. Seems like maybe just a worn spring?
Some carburator jet problems :)
bdw any advise how to get my parents to let me buy a dirt bike?
Check the needle. Or the jetting. Since its not a original pipe and the previous owner wasent the brightest mechanic and defenetly did something wrong to the needle/jetting.
It’s got a lectron so theoretically this wouldnt be a problem but it could possibly use a different metering rod
@@jasonjavelinye
The main jet is to high i had the samme issue
You might have hooked up the throttle backwards
Check the reeds
Hello . Im from Philippines 🇵🇭. And i am dreaming a dirt bike too 😢. I hope i win someday ❤
Either too lean on the rod or rod facing wrong direction just happens to me
BeRAD has a video on how to tune the lectron carb:
ua-cam.com/video/Pz4JF-NSHho/v-deo.htmlsi=lXKCeLkukBY2Ubc7
Love the bike, mines a 99, wish id have gotten a slightly newer one for the updated plastics, but she’s nice regardless. Mine also has a lectron, his video helped me out huge.
Probably running lean from poor tuning or because of gunk in the carb.
I am not a fan of those carbs. They're too finicky in my opinion. Also, you never know if the previous owner messed with the card so I would just take it out to a full clean and break down and make sure everything is working right. Honestly if it was me, I would put in a keihin carburetor and move on with my life knowing that I'd be able to sleep peacefully at night. 🤣🤣🤣
One of your carb jets is clogged
Them lectrons are more pain then they are worth, and you loose power. A well jetted stock carb has more everywhere
good video man
I think you spelled your last name wrong.. it's spelled pavič/ć ✌️😃
Cracked reeds can cause that
If that guy you bought it from put on the carb,---it is messed up. :)
Thank your lucky stars that he did not start it with that clutch set up. Gear Teeth would be missing, but at least the low oil volume would not have carried the teeth fragments into the rest of the tyranny. :)
❤
Sounds like an ignition issue
I don’t think that is a “bog”, it’s blubbering/ sputtering (to rich). Or that’s what it sounds like to me. I saw Lectron guys comment, I disagree in my interpretation of that sound

Clean the carb
