Check out Cale's POV from this same moto! He hung in behind me for the entire 15 minutes ua-cam.com/video/L2_r6-fxugY/v-deo.html
Great riding Jeff to help the engine last longer i would turn the air screw down or right 1/8 to a 1/4, you may need turn it a 1/2 turn down on cold day if your running 50:1 motul 800 with 91 or 93 mix you should also try 1 bigger main the way it is right now. You can also stick with 60:1 it will pull more fuel on stock jets, probably the same air screw but you ride hard and going up a size to 37.5 and 455 should not run rich at 50.1 turn air screw up 1/8 to 1/2 turn. turn idle screw little in or right to help cut off some extra fuel at idle that will help it idle with bigger jetts if you want to stay with pump gas at 50:1. or 37.5 and 455 60:1 u4.4 7.5% oxygen run gas out off carb after and your good half price of mrx02 and will give you a least 2 hp more coming out of the turn just more finicky on limiter with air screw throughout the day and keep a 460 main in your tool kit 6 mill socket hand thread on and off so you never drop a jett on the ground wrench to break loose and tighten a little Another great option is is to run 1:1 c12 to pump at 50:1 turn air screw out or left 1/8 to 1/2 will keep the bike cooler and more consistent power throughout the day ounce you get the jetting/setting you like you still may need to pay with the air screw in the 1/8 to 1/4 or up to a 1/2 depending on the day temp elevation if you get lost on the air screw turn all the way to the right then turn out 1.5 and start from there but hopefully this helps keep ripping!!!
Pro National on the 250…I vote yes
Definitely a yes vote. He even looks faster on the 2stroke
For sure
4:17 you put too much pressure on that guy 😂
I knew the camera was on. I felt the pressure for sure 🤦♂️
Scaring those four bangers to death! They hear that two smoker screaming up behind them and they lose their shite! 😎
Awesome video!
best motocross onboard channel on earth!!! Greetings from good old Germany
Boy, Jeff really set us up on that one! I thought we were actually gonna see this dude ride like the rest of us mortals and struggle on his 2smoke. Nope. That was probably the fastest laps ever spun at motoX. I'm blown away. Bravo.
Dude, you are so fast and so smooth! Keep making the best POV mx videos out there!
Nice to se you on an 2 stroke ☺️☺️😊
Day 119 of Cheering on Jeff: GO JEFF!
The legend
“I didn’t touch him, I swear” had me rolling laughing 😂
If you want a suggestion on tuning I would suggest going 40:1 and jetting for it. 50:1 is not going to lubricate your top end as well at those high rpm’s as 40:1. Just trying to save you hassle I remember all the build videos on this bike and when it blew up. Best of luck enjoy the 2 stroke 🤘🏻
Let’s see a lap time comparison of the 450 and 250 same day same track. And keep more convo in video I enjoy dirtbike talk
Dang your apex corner speed was aggressive and fast today - no delay just attacking - good stuff
Jeff Walker vs Jay Dalton 250 2 stroke battle!
I like this
Dang dude, you are wicked fast out there!
40/1 mix will keep the top end from burning up on a track, you may lose a nice smooth idol but that’s ok when trying to protect from the heat of higher RPM. I’m quite familiar with the issue (almost 40 yrs). Keep ripping and being awesome!
32:1 on all high revving bikes for me. 🤷🏼♂️ Still have a good idle. But even if I didn't, I'd still run it. When you're racing the idle doesn't matter anyway
This bike requires 60:1 to operate properly. Mxa did a test and the bike runs like shit with any other mix. Including 50:1.
@@mav459 They just didn't tune it right.
If you actually knew anything about 250 two strokes is that 32:1 is proven to make more power and protect better than 40:1
Ik it’s not the easiest, but I’d love to see some 3rd person videos of you riding!
Hey buddy they're is a weird clicking while on the pipe and from what i hear it could be comming from a little loose from your crank or if ur lucky check on your exhaust sleeve??? Top rider my man your getting better every vid that i see u ride skillfull!!!!! 👆🤙
do you clutch it when you upshift or just drop the throttle a bit and click up without the clutch?
Long live 2 stroke !
Nice bike nice riding 👏🏼👌🏼
Flying J walk perhaps will see a lil Red Bull straight rhythm redemption on this 2 banger
Would’ve loved to see this thing rip at the two stroke nationals this year
Proper bike ✊🏻
Bro the intro with the fly down is insane behavior
You tell him lol!
If anyone wants to learn about Jesus Christ reply
So you haven't spent any time at a track then??
Seeing as how she is Jeff’s sister…
@paulwalker3067 Well she should be used to then... lol
2 strokes for life
Yeah!!!
I have the same bike. 2020 Model. Both the Mikuni, and keihin AirStryker are great with the right jetting. I run 50:1 Amsoil Dominator 50/50 Gas/C12. If you get either, I have some good jetting suggestions if you need some. Heck, if you have one already I probably have the needles/jets and slides for you to try out.
Definitely some detonation going on while at wide open throttle and under significant load (that barely audible and sporadic sound of marbles bouncing around the jug is a dead giveaway). Not sure what insert you're running in the head, but that is either a jetting too lean, timing too advanced, or insufficient octane issue. Sounds pretty good otherwise.
I had a 2014 250 SX that was stock besides the 300 kit I installed that would make the exact same noise that ended up being a tad lean and richening up the main slightly cured it.
Good luck on getting it sorted, as that can kill those cast pistons quick.
more 2 stroke PLEASEEEEE
U definitely are at fault for KX guy falling😂
I got camera shy 🤷♂️
You gotta race that thing man.
Yea bro, sounds a bit pingy with some detonation off the revs, might want to mix 40/1. Definitely will save that top end. I’d look at jetting with the FMFs too. Try VP T2, it’s already premixed. I use that in both of my T2s. Else-wise damn bro she rips.
I've never really ridden 2 stroke, Do you ride it much different than the 450?
Being able to call that dry conditions makes me so jealous 😂
It’s the carb and head combo causing the pinging you need to probably make it richer
one kick bandit lol that's my 2001 CR250 🥰
She sounds so crisp, and you keep her singing! Dope vid! 👌🏾👍🏾
No dope.
A pro with 0, 2 stroke experience... These are different time they are... Nice ride it was.
Hes had 2strokes before and the started the channel with a CR125🤘
Do a national on it with Matty B it'll be sick to hear the fans go nuts with 2strokes racing.
Pinging is bad for any engine needs to be richer though the mid top.
🇭🇲🇭🇲🇭🇲🇭🇲🇭🇲🇭🇲🇭🇲🇭🇲🇭🇲🇭🇲🇭🇲
2 stroke 250 best bike ever made
What camera weee you using for this? Absolutely CRISPY footage
Sounds good. Maybe less compression.
"I can't promise you I'm gonna go out there and lay out a session."
*lays out session
Sounds lean to me. Have you tried a bigger main jet? With that different head making more compression probably needs more fuel.
Go an 1/8th of a turn richer on the power jet. Should eliminate the ping. Aside from that sounds dope af!
2 stroke national?!
So are you gonna try the 2 smoker at the Nationals,,? Would be Amazing content and exposure for you and your sponsors.
op coil/cdi
Rippping it
sounds amazing but im not a relighable source i just ride i dont tune bikes or fix them
You probs wanna run it on 40:1 and tune the carb to stop that pinging
sounds good but the audio sounds distorted a bit so it's weird.
I’d say ditch the lectron and put a Keihin pwk airstryker on it
C12 50/50 with 91 pump will get rid of the pinging
Lectrons do not run particularly great. You’ll struggle with pinging or running too fat no real in between.
Right now it sounds lean. Also make a note of how you have to work that clutch like your on a 125. That thing seems down on power. I know you’re fast but the bike sounds like it’s underwater, listen to your throttle when you get back in it after chopping. It has a big lean guwap in there.
Just try a different carb that takes brass. I prefer a keihin but even the stock mikuni works better than the lectrons. Lectrons are for typically for lazy trail riders who want to ride at 2000ft and then the next day at 10000ft. You’re a racer. Put a real carb in that thing and let her eat.
I’ve owned a lot of these ktms and still do own two. They run best imo with a keihin, a high compression head and a thinner base gasket for a basic budget build engine. About .042 on squish. You can get crazy with porting if you want but the stock ports aren’t bad if you move em a little with a base gasket change.
that's some great info, I appreciate it a lot!
you gonna be at fox this year? also yeeeeeeeeeeeeeeeeeeeeeeeeeewwwwwwwwwwwwwwwwwwwwwwwww
Put a 38 pwk on her jetted properly and all lean issues and detination will go away.
I'm an old school 2 smoke dude. 50:1 is way leaner than I have ever run mine. Is that a phathead thing or a newer KTM thing? 32:1 or 40:1 always in my past. (Now on a 450 myself but gonna pick up another 250 here soon)
Most new 250 2 strokes run 50:1. 125s 40:1. 32:1 is definitely an old-school thing at this point.
Sound alright?
😂😂😂
Um…. Yea!
It sounds good just a little off
Bro eats shit….“I didn’t touch him I swear”😂
by the sounds of it all you need is a re pack. very raspy
wondering if its my speakers but is the sound quality of the video terrible for anyone else for me it awful might of been the bike idk
Might need to go fatter on the needle or main.
Judge: Ok, now show us on the doll where Jeff touched you
Jeff: 4:24
I'd still take the dirt over Missouri dirt anyday
Almost sounds like it's detonating a little bit. Could be wrong just judging by the video.
I'd say fatten it up just a little bit but sounds great otherwise!
First lol
ditch that lectron
Might wan’t to go for a 40:1 or 32:1 on oii because 50:1 is kind of lean
That's what the newer KTM's are required to run on. 40:1 is way too rich even for them you'll have oil coming out of the silencer.
No it’s not. 50:1 is actually more oil for that bike than stock. Stock is 60:1 if you run the motorex oil. If you run castor you’re going to be at 50:1.
This isn’t a 1999 cr250.
@@user-mo8tm4jw2l My buddy had an 18 and ran 50:1 with Castor so that makes sense, thought it was the standard
Thanks for the correction, Castor smells sooooo good
@@carsongallegos5211 I had an 18 250 before I got my 19 300. It was 60 stock and also castor at 50:1. Your buddy is on point. Understandable to be confused when most 2ts do take 40:1 or 32:1. My 04 kx125 I run on 40:1. I wouldn’t consider running at 50:1. But the ktm is fine that way? Idk. Maybe something to do with materials science progressing. 👊🏻👊🏻👊🏻👍🏻👍🏻👍🏻👍🏻
Bean oils the best thing since sliced bread it’s all I want to smell 😂😂😂😂
why would one use 50:1 oil ratio? seems insane
I have been running until 800 for 30 yrs and it is made to be mix at 60 to 1 or even higher. I run it in all brands of 2 smokes and never had a failure.
When you have a newer 2t they’re designed to run a different oil ratio. My 04 kx 125 gets 40:1. My 19 ktm 300 gets 50:1. Stock is 60:1 but when you run castor oil you generally go to50:1.
Bike is WAY too lean on the metering rod. Best thing to do is put a Keihin air striker on it and get rid of the lectron. Also 50:1 is way way too lean. Run 32:1 or at least 40:1 or it won’t last long.
Oh thank Christ someone else besides me who’s screaming get rid of the junk carb and let the bike get proper fueling. Lol. Keihin is win. Especially if you 36/39 taper bore and wing them. 🙌🏻🙌🏻🙌🏻🙌🏻 doesn’t get any better.
You’re 200 percent right. Bike is way lean. Big guwaps on on off throttle inputs.
Bike sounds underwater and revs slow. Mega lean.
However I highly disagree on oil and how long they’ll last. I run 50:1 and I have 185 HARD moto hours on my 300 16.5:1 compression. Straight c12 on 50:1 blendzall castor oil. Vet A 165lbs. I’m hard on stuff and my crank/rod is still the original crank and rod.
Definitely agree the carb is lean, but the new KTM 2-strokes call for 55:1 on the fuel. I was being safe at 50:1. Of course the older 2-strokes need more oil, but the new bikes are quite different
@@JeffWalker84 Well the new bikes are EFI so that’s just what KTM has mapped the engine to run to which I still think is way too lean for a moto in my opinion I’d run that in the woods since you lug it more then. Swap it up on fuel mixture and you’ll get more power out of it and it’ll be a lot easier to ride. If you do decide to get away from Lectron hit Derek Harris up at HP development for an STIC block to go into the keihin airstriker carb. It’ll make a huge difference guaranteed.
They sweet till you ride dry hard pack then suck haha
Bike is detonating
Run 40:1 you might get some more torque it is a but lean id say
why is the audio so bad almost unwatchable
Would you mind elaborating? One other guy said it always sounds bad while watching on his Roku, but sounds fine on other devices. It sounds great on my PC and phone!
@@JeffWalker84 The only way i can describe it is when u leave the aux half unplugged and it still plays audio, but it sounds like its through a fish bowl. Ive tested on my PC and my phone
Do you think you’ll post a video from delta raceway? @jeffwalker
Making it look to easy man🥹
bro said dont expect much and flies through the track 😂
