You're going to love the STIC on that carb
I hope so!
Working man hands! Shout out to Brad!
exactly!!
Nice can't wait to see it finished and you brappping!!!!! it
thanks, me too! ;)
Nice video, i really like the 'purple line' hoses! Need to put those on my ktm 250sx build!
thanks, glad you like it. go for it!
He said ‘ that float bowl height will figure it’s self out” 😂
I watched this video to see how to set a float bowl height, lol......
I was trying a JD Kit on my Sherco SE 250 2020. She was running way to lean. I ended up using bigger Jets and the JD needle. Now she is running better.
"it looks good.... " :) ha ha ha understatement of the year... so far :D
haha, thanks Emil, but 2021 is still young ;)
The engine came out great
thanks Bersisa!
Awesome... Can't wait to see it when its done
Me too!
Can't wait to see it all together!
thanks Aaron, me too!
The engine looks sweet. You should get the oil fill plug ceracoted black to match the head,
thanks, interesting idea!
u should ask brad for his first impressions of the bike when you are done handling power ect
yea I should
@@dirtniron I think it would be interesting
Very nice
Thanks
Love it Brother!! Hope youre staying safe
:)
thanks brother, you too!
thank you again, I checked the boot, no leaks found... then I took out the air screw and no washer and o-ring is present. I wanted to double check if it is needed (no o-ring in Keihin diagram) and you just confirm what I thought to be the air leak coming from. For the idle screw, I guess is just a sealant paste on the thread, mine had some gray stuff on it but not sure what kind.
yes there should be a washer and the oring, that can do the trick.. is it running ok now?
@@dirtniron i have been on a longer trip but because it was weekend I didnt had the chance to find an o-ring, but it is rideble, sometime stall easy but I am already used to ride it like this. The fix will follow :)
Great video and great job by Brad! Could you give us links to the carb kit and the vent hose? It really helps when these videos put links to the products being used in the video description.
thanks Will, you are right would be good to share the links. go on JD jetting, they have it by the bike. same for the allballs
Thank you,
Just got a real maikuni pwk cheap on amazon but it had no instructions in the can.
I didnt understand the vent hoses 👍
Glad I could help
Nice! Have a nice day✌️
Thanks! You too!
Looks amazing
thanks Nick!
Great job done. Thanks for sharing. :)
Thank you! Cheers!
What was that little o ring you disregarded right before you started doing the hoses?
Wow that’s a pretty nice carburetor.👍🏻Hey Rado you should post the names of your songs like before they start on the video
do you like the song? its just a one song in this video. I started to buy the music, so thats why dont really post the links these days..
👍🏾
Si estuvieran en Ecuador les pediría trabajo y sin sueldo con tal de aprender mucho. Son los mejores en mecánica.
thanks, glad you like it
Questions... What JD Kit did you use? They have one for SX head and ignition and another one for XC - XCW bikes with XC head ignition.
sorry, dont remember
@@dirtniron All Good - I got it figured out. With SX head and ignition - I did the Race kit. Red needle 3rd clip, 38 pilot 158 main. 1000-3000ft level I also added the #7 slide and the bike is amazing!!!!
Fantastic.
Glad you think so!
Looks alright... :)
yea.. kinda.. ;)
Smartcarb all the way. No jetting ever ! 👍
maybe later..
how come you and or brad decided to use silcone instead of a gasket for the main engine cases?
Are the vent lines looped over the top of the carburetor to try to keep water out?are there any negative effects from not having your vent lines looped?. Serious question no foolery
Didn’t look to be any measurement taken on float height.
we checked it visually, all good
😎
On my Keihin carburater it says: 51 SAO OKV. I am not sure if it is 38mm. I have a Gas Gas EC 125 from 2005
Can you tell me by the code?
thanks!
Ya, I’ve heard some of your previous songs too and would like to know the name
Insane. Rado, what you think about carb swap on CR250R 2006 to the this one from 300 XC , or KTM 250 XC Keihin PWK 36s AG.
I think this carb is great, try it
@@dirtniron thanks, im from Ukraine, Zakarpattya, near Slovakia. Time by time work in you Motherland.
For now i hav Keihin pwk 36 ag from ktm 250 2004. Very hard to find 38mm like that what you propose.
love that part of Ukraine, were exactly do you live? good trails in the mountains? do you happen to have a video from a trail ride?
@@dirtnironnot small village Dovhe. Closer to Irshava, Mukachevo, Mizhgirrya...
Yes for sure. Now i not ride to much, most likely wrench rabbit))) I work in Poland. But my good friends ride all time and they have channel's on TH-cam
nice
Thanks
my wr250f 2005 carburetor is leaking from float needle seat and i can’t find it like new part oem or aftermarket i don’t know what to do the bike is running so rich can you help me
i am sure all balls racing has the rebuild kit for you
@@dirtniron the problem is in the float needle seat it can not replace today i tried to polish it but no effect ... the valve needle is in good shape ... i don’t know the needle seat has an o ring maybe not
What is the red needle part number? Because a 162 main sounds small for a 300.
Red needle is for high elevation, hence the 162 main. They're probably around 4k+ feet.
What’s the part number fir the rebuild kit? I can’t find it on their website

as long as its the same carb (keihin 38mm) you should be fine
Sou do Brasil como comprar mais barato as pessa aí
Where does the smaller of the two circle orings go? You don’t show, the bigger one is used on the float bowl drain plug. I can’t figure out where it goes!! Ktm diagram doesn’t even show it
You can see it left over at 3:41
it might be an extra for different models.. I am not 100% sure
It's to adjust the needle by 1/2 clip position.
You don’t set the float level ?
You only need to set the float level if you or someone else previously messed it up. The factory usually has the float set at the correct level. Bend the tang up or down and that adjusts the float level. The more fuel the richer the lower the fuel the leaner. On your needle the top (highest) groove is leanest, as you drop the clip lower (bottom groove is richest) it becomes richer. Your jets become leaner as you go down in number, and richer as you go up to a bigger size. If your more then 2 to 2.5 turns out on your airscrew your pilot jet needs to be resized, same as if you are 1 turn or less. Optimal for most bikes is 1.5-2 turns out on the airscrew.
it was good, no need to adjust
Where can I get the hoses?
nihilio concept has some
they are actually Honda stock hoses
This is an absolutely useless video. It was a speed exhibition instead of a how-to.
throw it out buy a lectron
well jetted Keihin runs great
you skipped througn most of the in depth rebuild then speed through it in the middle of the video.
yea, I did not have a good footage.. will do better job next time
