Why Does This Old Dirt Bike Run TOO RICH?

In this video we work on Hard Times some more. The engine runs too rich despite a clean carburetor with correct jetting. We talk about symptoms of a 2 stroke engine that is getting too much fuel, and try out a possible solution. Bike is a 2001 Gas Gas EC300, and the carburetor is a Keihin 38mm PWK Airstryker.

One of the most genuine channels I watch on KZbin - it's thoroughly refreshing!

[@davidrunyon8328]

A real one for sure

[@peteramberley9952]

Don't beat yourself up over editing.we love the pair of you as you are.❤

[@ChiefStones]

I'm always happy when i see a video from the 2 of you.

[@jan_vyhnak]

A blessing from the lord(s).

[@wannaseethevid]

Ahh, a Jennies garage show! it is 4AM here in Japan, -2 degrees and I have a broken window. BUT I have beer.

[@answerace]

Check the jet block and jet block gasket of the carburetor. These can cause rich conditions that can't be fixed by jetting changes due to allowing unmetered fuel to leak past.

[@MrSnowman777]

I think he did that on the KDX but it didn't make a difference

[@joeuknobro]

I was just about to say this as well. I fought this issue for a long time. JD jetting sells them for mikuni and keihin carbs!

[@jenniesgarage]

You have a good memory!

[@jenniesgarage]

I have heard that oring can cause trouble, but have never come across one that had failed. I do remember hoping replacing it would help my kdx200 carburetor, but it wasn't the issue. Thanks for the comment!

[@aaronbright5028]

​@@jenniesgarage try 32:1 with original carb. If that still not the fix then I'm with this guy on jet block. If you ever have questions or need help I work at northstate powersports in chico I'd be happy to help you out

[@80SWoods]

I would check the basics and make sure the float height is right and the needle is at the stock clip height (if it’s adjustable). It’s possible that someone tried to hot rod it by jetting it too much. People do funny things trying to make more power. Also (I need to remind myself of this because I always jump straight to the carb for nearly ANY issue), but a weak spark can cause a rich condition, but that’s likely a long shot to be honest.

[@motorcycleman3322]

exacly i agree same thing happened to me with my cr 250 .

[@Dsw009]

Weak spark bc of coil that deteriorated could be very possible. had that happen quite often , the last couple of bikes I had. I think here is more than likely rings and maybe coil

[@hhstarwars]

@@motorcycleman3322Honda cr250 or husqvarna cr250?

[@brettdawson4381]

​@@hhstarwarsthink gas gas 300

[@brettdawson4381]

Maybe crank seals on the way out 👍

[@Jimmy_Watt]

The wholesomness of your wife and you running this channel is wholesome enough, (my wife wouldn't dare), to get my attention. The fact that you actually fix things is icing on the cake.

[@breakingdaniel84]

New Jennies Garage video!! Today is going to be a good day!

[@DeathColdBeer]

Why are you guys so good to us? everything about your content, jokes, humor, it is genuine and great.

[@truejim]

When you said you could fix Hard Times' rich-mixture problem with things around the house, I figured you'd integrate Camera Girl with the carburetor...on accounta she's always a breath of fresh air. (nyuck nyuck nyuck)

[@chukpic]

Are you related to them?

[@jenniesgarage]

Very good!!

[@no_handle_required]

This is the ONLY channel I look forward to seeing updates from now. I don't know why. It's just the best feeling to watch anything you guys do.

[@brendanabbott2809]

Clunky video is better than clunky hard times...keep it up folks!😊

[@jameshilliard7576]

I'll take what you call "clunky" editing to keep the content flowing. I love the channel! I once changed out a worn out carb on an older 2 stroke golf cart with a replacement. It not only brought it to life, but I saved enough money in gas to pay for it in a month of use! Keep it coming however ya can!

[@Paaaull]

All the talk about carburetors reminded me about the video what was one of the 1st videos i watched from you, where you were testing fuel consumption between worn out, chinese clone and new genuine carburetors. I still think about that video every time i mess with carburetors

[@jaime7890]

Wasn´t expecting a new video. Such good news!

[@dean754]

I have the same bike and had all the spooge and smoke also, yours sounded better and responded better to throttle with the second carb. However , only adjust the air/ fuel mixture when the bike is warmed up as you’ll be chasing the wind in your setup if not. Love your fun videos guys, you explain things really well.

[@Free_Ranger_CT110]

Fuel/air mixture screws in or out to lean or richen the idle circuit changes whether it's before or after the slide. On your carb with the screw nearest the air inlet it's an air screw. It was originally screwed fully in which makes it rich. If the screw was on the engine side it's a fuel screw & turning in reduces fuel making a lean mixture. Love the channel & caught the lord of the rings potato reference. Precious!

[@dugsdub1981]

Another awesome video! Hopefully hard times is running better! Can't wait for the next video!

[@johnleu3217]

Extremely glad you guys came back missed this so much

[@darinblomquist422]

Always the best videos on the tube! Thanks

[@CurtisMassey]

Good stuff guys. I love the troubleshooting process. Can't wait to see it in motion.

[@tjtobin86]

Love the extra videos lately!

[@mickfbr]

Always very happy when I see another video from u guys 😊

[@protapanzer8752]

Thanks for making. Your videos always make me happy.

[@nolz262]

Yewww love a JG upload, loving the hard times videos too 👌🏼

Always nice to see you guys! 👍❤️

[@flashgordon1695]

most genuine DIY channel ive come across on youtube keep up the good work

[@FriendlyRider88]

Love this channel I’ve watched it for quiet a while now,

[@christopherjones9487]

Love the video!! It’s great to see you drop two videos so close to each other. I am not a motorcycle guy, but I have always enjoyed your videos. I am a long time subscriber and I have always felt it would be nice to see more videos from you. I truly believe if you could manage to drop a video once a week to every 10 days that your channel could really really grow. Don’t stress the editing, me and all the people that watch your channel enjoy the content that you and your wife put out. I wish nothing but great things for you two, and truly hope to see more and more content soon.

[@bertamusprime618]

Another great video! Keep up the great work and I am growing an attachment to "Hard times".

[@brenttaylor7583]

Very happy to see regular content from you guys again. Keep camera girl smiling!

[@maxwellhines3216]

Greetings from Somerset, we’re neighbors. Love this channel!! Been watching for years

Man I loved this video, didn’t even notice the difference at all!

[@lennycruz4558]

you being so real and positive 😊makes me love your videos

[@fadedlight8596]

one of my favorite channels of all time

[@moto3463]

Best channel on youtube imo I love this stuff.

[@geexskill]

Hello guys, thank you for this video. I love to follow the Hard times recovery. I'm hooked to the carburator tunning arc! This format more RAW is ok for me. I watch your videos to see mechanic, dad jokes and smoke!

[@Juggernaut-fg2up]

Appreciate the videos bro, thank you. You are very relatable I think that's what makes them so good

[@Teraraki]

My vfr800 has been giving me plenty of trouble lately with the charging system, these videos always help with the downtime of waiting on parts

[@claycarrie7787]

Great job! I love all of your videos, even ones you don't spend as much time editing.

[@eneharu]

I love both of you so much, this channel is so wholesome, and I've learned so much. I just want to say thank you. Both you, and your wife.

[@vortex812]

Adjusting the mixture screw way too much at a time. Also the crank case can hold oil/fuel down in the bottom. Gotta clear it out. Also gotta warm that thing up! It's not going to run perfect when it's cold

[@1991enduro]

Enjoyed this vid got half way through and as called to go be busy but I'm back and commenting 😊

[@PuchMaxi]

Epic mullet Jake!

[@phgoil]

I was kinda let down you didn't want to fix it completely in the last video. Which makes me much more happy, you changed your mind :)

[@craigcorbin4098]

Woohooo! A new JG episode! Always a great day when this happens!

[@ScrapPileRepair]

Yes! New Video! Thanks guys!

[@just4kicks950]

You two could easily have your own show on tv 💯. Wanted to say thankx for the awesome upbeat vids 🎬👏👏👍🫡.

[@jamescornflake1542]

I love how ye compliment each other. Easy to view. It's like ye actually don't give a shit and just do your thing anyway which is refreshing)

[@idan1358]

Love these vids, your channel caused me to create my own, I had a leaking carb issue which poured most of the fuel onto the floor, once I fixed it, I did a burnout then bought a new tyre😂 not a plug but if you want to watch - it’s called “wife’s out bikes out” That vid is because of you guys😉👍 btw I full restored that bike and sold it, wouldn’t have happened without you two🤙🤙 From downunder🤘

[@johannesversendaal4554]

You guys are the best.

[@jenniesgarage]

Thank you John. Good to hear from you.

[@noahcorkum2926]

It's a good day now got a Jennie garage video 🎉

[@villarreal2025]

my day is made, thanks!

[@Davojo]

Nice video as always!

[@averagecarguy420]

I like these kinds of videos. Feels like back in the day Jennie’s Garage.

[@toddmccarter45]

Always a good day when theres a new jennies garage

[@zeewolf1116]

always fun to watch. :)

[@badmotofo]

Two strokes tend to 'load-up' if not run through the RPM range. I always take mine out to the street and do a quick run through the gears in the power band to 'blow out' the system before tuning. It will run a lot cleaner after that and you can more accurately access the jetting. Love your guys channel and look forward to many more videos.

[@paulmckinder3082]

I love your channel honest people honest videos and can have a laugh as well fantastic. Sorry can't help on the bikes as I have no clue as Im thick when it comes to mechanical things but I do love hard times

[@drsavage99]

agreed. it does seem to be running better than it was. Hopefully it will clear up during the ride

[@leonardslade903]

My favorite channel.

[@HeroRR]

I love your editing, but if you this means more videos then i'm more than alright with this format. Keep them coming!

[@duskycotw8404]

Glad to see you here

[@ShaunHensley]

"Words aren't the best thing for communication, but that's all we have" CameraGirl you got something special here😂

[@johnmauer6079]

I have a KTM shows the same Sx and the jetting is like a fire hose. I was so confused when I dropped stock jets in it. Thank you for the video so helpful.

[@bigdaddy741098]

It definitely seemed better, but I'd watch a rebuild if it needs it. Thanks for posting.

[@geigertron3000]

WOOO HOOOO!! great video good times with hardtimes!!

[@iamnickdavis]

Camera girl is full of it this episode. Keep the great videos coming you two!

[@rosshawke8953]

I have the same bike .didn't Rev out like yours. Redone the exhaust paking now it kicks arse

[@StrawDragon]

Love your channel.. But you looked very experienced with your hand motions while coughing! Keep it coming :D

[@just-in-time6069]

Usually in rich case I'll drop the pin first and go from there depending on how it runs in top also it look like it's do for new rings that's alot smoke but iam used to 32.1 when I drag race and only use good oil and fuel keep up great work and have a wonderful day.

[@willredekop6304]

Ya buddy, new videos... keep em coming brother

[@lunchbox90]

I'm ready for another long format video. 😤😂 being someone who grew up with ADHD, this channel is too entertaining to not learn anything from.

[@tychozeeman8315]

Great to see more video's

[@jenniesgarage]

Glad you like them!!

[@TheProCut17]

I'm confident you'll get it right

[@jenniesgarage]

Thanks!

[@frassonracing]

If those new shoes don’t have “optimism” and “delusion” written on them by next video, I will be bummed😂

[@magstrikefjerstad3192]

Just made my day!

[@jamescornflake1542]

08:16 He introduces his latest creation. A mechanical Octopus))))

[@perennialtortilla]

I was running 40:1 on my yz 125 out of ignorance. I experienced all of these problems you have. Spooge, hard idle, and lots of smoke. I switched over to a JD jetting kit and that made it worse. I changed to a 32:1 ratio and played with the mixture screw and it perked it up immediately!

[@cmc7106]

Great vid and congratulations on the new shoes !!! 🤣🤣

[@jenniesgarage]

Thank you!!

[@yggdrasilygg]

its about time the algorithm brought me back to ya.

[@aaronkerr3541]

Love you guys

I wanna see you more often, too!

Just need more of them

[@jodyhakamaki5602]

Hey welcome back again...

[@jenniesgarage]

Thanks!

[@1MrMegaPilot9]

I would watch you explain why you liked a certain penny more than another. Even if the video is choppy! More content! Yall are awesome!!

[@Ironsights85]

love the content, edited or not!

[@monsterkxf]

Check the exhaust packing too, it might be saturated 🤘🤘

[@ThrottleAddiction]

The hair is coming along nicely.

[@Jrockilla137]

My guess is the previous owner messed with the jetting trying to make more power without a clue. I'd check what jets are stock against what's in there.

[@rigguyjt]

Sometimes the jet needle wears down the inside of the emulsion tube. Remove the needle and drop it straight in. If it goes all the way down, it’s worn out. I’ve had the lay happen with Keihen carbs. Had a 1994 Suzuki 125 that needed a carb replacement because of that.

[@Fireballsocal]

Residual Goo, the new name of my punk rock band. Now I need to find musicians. I have the triangle covered.

[@ncopp4358]

That oil you see dripping out of the exhaust and the slow response from the idle air screw tells me that float height is set too high up leading to poor atomization and a perpetually rich mixture that your can't really tune otherwise. Running a rich jetting can do the same but it REALLY has to be running rich for that happen to that same magintude. Realistically, don't touch any of the mixture screws until you checked and adjusted the float height. For those of you who are new to this, there are very fine holes on the main jet at which gas passes through creates a fine mist for better combustion. If the float height is set too high up, then gas overflows past the holes rendering the small holes useless for atomization. So instead of a nice even mist of air and fuel, it just large droplets of fuel that get hung up on the rest of the intake and the bike will run poor, and if the float is set too low, then you will get a perputual lean condition that no matter what, it will run way too lean or way to rich if you attempt to tune for it.

[@mr.whiskers6273]

Hey loving the vids for a while now! The airscrew is an easy beast to tackle, turn the screw fully in not tight just against the seat and then turn it 1 full turn out and then half so 1 1/2 turn total this should make for a good tuning base. Turning in the screw will cause a rich running condition at idle till 1/4 throttle Turning out the screw will cause a lean running condition till 1/4 throttle Give the bike a lively idle and then turn it down do a desired idle when the bike is warm. Hope it helps you’ve been one of the driving factors of me chasing the 2 stroke beast! Bye :)
