Basically, if the engine is in good mechanical operation, all you need is 3 things to run. 1) Enough compression to lite the charge. 2) Spark at the right time. 3) A good air/gas ratio for the fuel you are running. If the engine is sound mechanically, it will run. If compression is good, and it sparks at the right time (strong enough spark too. It takes more energy to jump the plug gap when in the cylinder under compression/turbulence, and you can be fooled by a outside spark check.), then the carburetor is all that is left.
Well I learned more about a carburetor today. Thanks for the info on the clip. Also learned how to tell if it’s running rich. I didn’t have an ear for that but now maybe I do. Appreciate your work.
Good folks in the comments section. All he did with the carb is rig the o-ring seal, and I am sure he has replaced it with the proper o-ring by now. There was no carb adjustment (jetting, float height), that we saw here, but he did mention moving the needle clip to a more lean groove. 2-stroke engines with a carb are always sold new on the rich side, and they all can benefit from carb tuning. My 2019 YZ250 2-stroke is the worst I have ever seen (MXA said it was good jetting). So far, I have gone more lean on every jet (Pilot, needle replacement to a more lean needle, (ran out of grooves), and a more lean main jet and a more lean power jet. I still have to go one more needle lean, as it is still rich in the middle. But it runs much better now, warns up the coolant much faster. I will be 80% of the YZ250s out there wit the stock jetting also have damaged pistons, because the water takes so long to warm up, (may not even get the engine to a good operating temp), riders will take off too early with the piston crown expanding from the heat, but the cylinder is not expanding fast enough.
Can't remember how many subs you guys had back when i started watching but i do remember thinking this channel was underated. Wow.. look at you guys now! Congrats! Well deserved. Great vid as usual 🤟
Im happy to see you still have the trusty ol kdx200 i would love to see some new videos on the old kdx i wish i could find a 93-94 kdx200 front end to put on my old 92 kdx200 ive got to do crank seals on mine after 2 years the left side crank seal on my kdx finally gave out so i guess ill split the cases this winter. I wish i had a parts bike like the one you had a few years ago when you were building yours.
I don't think you need to split the cases to change crank seals. I have prick punched 2 small holes in the old seal, and used a puller (using sheet metal screws) to get them out. But it may not be a bad idea to split the cases to put in new bearings.
I try not to buy from communism of china as much as I can. Harbor Freight is a communist product retailer "O-Rings West" has any ring you need, but not sure where they are all made. We are going broke in the USA because free enterprise and communism are not compatible. Our federal government gave our free enterprise to communism so it can fund itself starting in 1978. Now, it is taking over the USA. Still a good deal to you?
I wish you came to Germany to fix my KTM SXF 250. You seem to be able to fix any problem 😄. I’ve been watching your vids for some years now and always learn something new.
Those mikuni carbs with the main jet in that bolt and relying on the o-ring can be a persistent issue. I have always just moved the main jet from the special bolt to where the brass fitting that has the o-ring goes screws into. Those carbs were just designed that way for quick main jet swaps. If you move the main jet like I said it saves a huge headache and eliminates future issues.
Kind of surprised you didn’t check the air filter. I have experienced old air filters not allowing enough air in causing the same conditions this motorcycle had.
Really happy for you in your new place. Looks like some great riding to be had there as well. The explanation behind the troubleshooting is top notch. Your helmet mic seemed to capture the audio in the garage better than the camera mic which made me think you would go next level with a mic that filters out garage echo.
Another Great one Guys! this is a helpful one for me , as many of your vids are, as i have 4 2 stroke suzukis now, all old as dirt but also smaller than this bike. even though that is a suzuki this was mostly carb stuff - o ring thing and boo boo wire probs. helpful on many other bikes that are hear and do what dirt bikes do.
I dig your channel, but IMO, refrain from asking questions in the headline like "Can we fix it?". Let the stupid channels ask such questions, because the answer is up to their skills. We all know you can fix it. You and your gal also seem to have a great relationship, (congrats). Not too many people can fix theirs.
Can you please fix your water heater flue pipe. It's supposed to be straight not multiple turns. I prefer hard pipe but that's just nit picking. Don't want anything to happen with your family due to Carbon Monoxide
Why is my favorite furniture flipping channel posting about motorcycles? On a serious note, what intercom setup are you using with the GoPro while on the bike? Audio sounded great.
I don't think that is gravel on the paved roads, just another road in the USA wearing out. I guess the taxes we pay to "fix the roads" is being spent elsewhere.
@ I agree, that's why I didn't say they were gravel roads, I said they were gravel-y. Which is exactly what roads are like when the asphaltic binder starts to break down releasing the sand and gravel the asphalt is primarily made up of. Source: well over a decade and a half in the industry.
Has anybody older school noticed that MXA magazine is pretty much devoid of technical knowledge today? They don't know how to jet a carburetor at all. I can go through the mag today (especially on 2-strokes) with a red pen like a teacher correcting a test. I especially enjoyed a flywheel weight explanation, that said they do not consume power, (they do under acceleration, because mass takes energy to accelerate), and can actually add HP, (they do when braking or decelerating). My goodness! They are not even sharp enough to understand they need to sue their schools. I don't buy the sales brochure called MXA anymore. A hollow shell of what it used to be a generation ago. Doug in Michigan PS. No, they can not fix this bike. :)
I worked on a Mikuni carburetor today on a Suzuki quad. It was running rich. Someone had installed to seat retainer for needle and seat incorrectly. I hope dude didn't put straight gas in the motorcycle.
I recommend that anyone that owns an old bike, motorcycle, or scooter should learn how to work on their own carburetor, or at least know how to replace it.
If we were in England, the Suzuki might have a slight "Moor". At the same time, "Bog" is slang for "toilet" in England (I'll Take a Nip in the Bog) so I guess you could say Evan's 250 is running like crap. 🏍💩🤔 🤣😂✌
Well, you can always fix the mechanical stuff, but there's nothing on this planet that can fix remembering to fill'er up with fuel before a fun run... :P
For an estate sale channel, this guy sure knows his way around a carburetor!
Huh?
Jenny's Garage is like a wholesome version of that Wranglerstar dork.
I am happy Jennie let's this fella use her garage!!
My favorite carburetor channel
I dont know anything about bikes , but this is one of my favorite channels..
"This is not a carburetor channel...but we find ourselves here often." Well said!!... carburetor whisperer. 😎
I'm so happy ya'll are posting again. Do what you do don't worry about the rest. 👍
Seriously impressive how you understand how it all works and diagnose
Basically, if the engine is in good mechanical operation, all you need is 3 things to run.
1) Enough compression to lite the charge.
2) Spark at the right time.
3) A good air/gas ratio for the fuel you are running.

What a great little bike Evan! the awkwardness between you too was on point! :)
That little Suzuki runs really nice 👍 he was real happy…great job Jake 👏👏👏👏👏

I could’ve never imagined that a two stroke starting up first kick without choke on a cold engine was a bad thing. 2 stroke music never gets old
Great work! That bike sounds awesome now.
Can't remember how many subs you guys had back when i started watching but i do remember thinking this channel was underated. Wow.. look at you guys now! Congrats! Well deserved. Great vid as usual 🤟
I was a pretty early subscriber too, back in the Shasta camper era! 😂
This guy knows a thing or two about carburetors.
Im happy to see you still have the trusty ol kdx200 i would love to see some new videos on the old kdx i wish i could find a 93-94 kdx200 front end to put on my old 92 kdx200 ive got to do crank seals on mine after 2 years the left side crank seal on my kdx finally gave out so i guess ill split the cases this winter.

I rode with some guys using the KDX200 back around 1990, and they were flying through whooped out Michigan trails. A very capable machine IMO.
Great carb fix them all Suzuki’s great bikes bring back great memories. I’ve always been an old-school guy. Love your channel. Keep up the good work.👍
“With time, things lose their springiness”
“Oh, I wouldn’t know”
How cute
Hahaha, once again, trying to work on my to do list. Now I have to stop and watch a JG video, LOL!
I love learning from you guys :) Doing all season motorcycle this year in NH, so knowledge might be useful.
You have the cheesiest jokes on TH-cam (bog, swamp, marsh etc). That’s one of the reasons I keep watching! 😂
Nice troubleshooting! Just an FYI - Harbor Freight has a 225 pc. nitrile o-ring assortment for $4.99.
I try not to buy from communism of china as much as I can. Harbor Freight is a communist product retailer "O-Rings West" has any ring you need, but not sure where they are all made. We are going broke in the USA because free enterprise and communism are not compatible. Our federal government gave our free enterprise to communism so it can fund itself starting in 1978.

Love seeing all the videos! Thanks! Keep em coming 🔥
I wish you came to Germany to fix my KTM SXF 250. You seem to be able to fix any problem 😄. I’ve been watching your vids for some years now and always learn something new.
Actually fixed it myself. The assertingly new engine had wrong valve clearance, thus starting issues and idle problems.
nicely done
Those mikuni carbs with the main jet in that bolt and relying on the o-ring can be a persistent issue. I have always just moved the main jet from the special bolt to where the brass fitting that has the o-ring goes screws into. Those carbs were just designed that way for quick main jet swaps. If you move the main jet like I said it saves a huge headache and eliminates future issues.
But they are so easy to work on.
Good repair Jake and supportive crew 👍👍
Awesome video. I always look forward to them. Keep them coming!
Kind of surprised you didn’t check the air filter. I have experienced old air filters not allowing enough air in causing the same conditions this motorcycle had.
Please fix the water heater vent. Enjoyed the video as usual.
I expected nothing less than like new, great job and video
Every motorcycle shop has a carburetor channel 😂😂😂
Really happy for you in your new place. Looks like some great riding to be had there as well. The explanation behind the troubleshooting is top notch.
Your helmet mic seemed to capture the audio in the garage better than the camera mic which made me think you would go next level with a mic that filters out garage echo.
I'm here to get my fix of carburetor movies!
That is a very good feeling when take a old bike and make it run better than it ever had before
That was always a problem with those carbritraitors. And usually when you were as far away as possible from a tool box and "O" rings.
Another great video! Thanks for posting.

Much, much betta. Still " four strokes" at top of each gear. Should get to redline.👍👍
Great times!

great bikeTS-250
Very popular bike in the 70's too.
For a thrifty living channel, these two know their way around a carburetor
You need to move into the right city and start your own shop. It’ll be tough at first but good word spreads fast
The new digs look sweet. Any chance of a video tour?

Pleasure doing business with you guys! 😎
Another job well done :)

Awsome work and nice video guys :D 😍
Me watching his test drive: I can't believe he is driving that fast on those gravely curves!
Me: remembers I am watching at 2x... Oh...

I hope dude didn't put straight gas in the motorcycle.
Was thinking the same thing about straiight gas. 😮
The owner of the bike never mentioned wether the fuel he was given was 2 stroke mix or straight fuel. I hope the piston is Ok.
I just had a after thought, maybe this bike has auto oil injection.
Another happy viewer
Great content
Aaaaw yea, just caught it as it was posted!
Thank you

I recommend that anyone that owns an old bike, motorcycle, or scooter should learn how to work on their own carburetor, or at least know how to replace it.
Carburator!! 😂
"Huh, i would know" comment made me 😃
Pro Tip: Don't test ride on 'Reserve'.
What State You Live Weather Looks Beautiful I’m Frozen 🥶 in ND
They're in CA
Yes
Are you sure you aren't a carburator channel? 😂

whatever state you guys live in is beautiful. is that northern california?
👍👍👍😁
Way to needle us about not being a carburetor channel.
How do you determine what subscribers bikes you would work on
That's what I thought
Greasing the speedo and tach cable wouldn’t be a bad idea.
My wife Marcia boggs sometimes when I don't take out the trash.
Well, you can always fix the mechanical stuff, but there's nothing on this planet that can fix remembering to fill'er up with fuel before a fun run... :P
Two stroke?
Beep
He could have said thanks, instead of an ungrateful "mm-hum"
Nice Junk 🙀🙊
So when you gonna set me straight on not being a homeowner and being a serial squatter?
You really still going on about that?
