I got a video of Chinese air strikers on a cb350. I choose them because they were cheap and I had no carbs, they run well , I jetted rich and ring it out to about 70mph. I lost bottom end but hey the carbs are massive.
At 1/3 to 1/4 and up, the cost of OEM parts, the aftermarket knockoff parts are often the way to go. I can understand the problem with the slides on carburetor you are talking about. The price and quality on the Internet (Amazon, etc.), is often difficult to beat for cheaper parts when you can use them.
I have ran a few, had to drill the main emulation tube to Keihin size and the fuel inlet as well! And when working on banshees it twice the problems to deal with! Had to run all keihin tuning parts including needles. They just aren’t worth the hassle and issues, put a genuine carb on and they tune out perfectly without fuss! Time is also worth money! LOL as a sidenote I’ve also had slides not fit at all and screw caps not fit at all as an interchange. Even had one set of carburetors that came with removable emulsion tubes, like a mikuni, super bizarre, and the emulation tube also extended up into the carburetor body, And effectively leaned out the mixture! I am done dealing with these! Would never buy again! Like some people have said they have gotten good ones, they work fine but if you have a deal with problems or potentially burn up a motor. $150 savings is now gone!
It also depends on the application, something lower hp, or not a crazy demand on the fuel delivery will probably be fine. I still don’t like that they are selling them aas genuine, and the price has gone way up on them
As 'AdamNicholas' said below v knock-offs are fine If you can jet them to fit your motorcycle. I had to modify my emulsifying tube to get the float of work. Besides that < there's not much to make spending $300+ for a supposed genuine Keihin worthwhile IMO.
No, normally 2 strokes just have the spring or I should say, carbs that have the mixture screw on the air box side don't have an o-ring/washer. If the mixture screw is on the intake manifold side, like many 4 strokes, it will have an o-ring/washer.
@@TepcoCycleRepair a see mines is a pwm 38 and it has an oring and washer I have purchased one of I believe to be Chinese sudco pwk 38 on amazon and noticed it didn't have the oring or washer
My TMX works really well. I liked it better than the Keihin. You have to do the o-ring fixes to the TMX or it will run rich. I have a video about it as well.
@@TepcoCycleRepair got one in the mail today slide on mine looks fine, only issue was sone burrs on some of the ports and bottom of float bowl, have yet to test it as im wating on headgaskets, should be better than the stock gx200 carburetor either way haha
Oh got it. It's not a normally replaced part in the PWK it needs to be pulled and pressed back in. I would use a q-tip and polish, and polish the crap out of it. I use valve laping compound for bad ones and semichrome Jewelers polish for all others.
I like how they take the slides and throw them in a huge bin during manufacturing, zero F's at that factory probably, although it most certainly a terrible workplace.

I agree when they work, when they don't it's frustrating. Lately I've been throwing money away trying them.

Blue and red JD needle is same,except the red is slightly leaner up to 1/4 throttle.
The clone carbs are awesome I have run them zero issues. Most people can't jet are carb doesn't matter what they pay for it
I wish that was the case with these PWK clones but if you can't change the slide you can't properly jet it.
Ah guys let's pay more attention to materials. Where the ore from with either of um. Shhhhhh

when you removed the air screw did any of them have the the oring and little washer regards scott

Looks like an easy & cheaper fix for a wore out needle seat, just swap jet blocks.
Thanks for the info.
@tepco cycle repairs. Is there anyway you can send me (or post) the link to that China carb. It seems like a very well made carb for a knock off
Buy it on wish
wincycles.com/p728/Honda-CR250R-Carburetor-1990-1996/product_info.html
I just put one on a 99 cr125 . I'm going to try a jd jetting kit
Can you add that kind of carb on a gy6 engine
Yes . use a 28 mm or 30 mm if you have a big bore kit
Where's the follow up? How's it run?
Left me stranded in the woods. ua-cam.com/video/jqqF36GunNA/v-deo.html
In your opinion, it's bettere a 42 Keihin carb. or an original 38 Mikuni Tmx?
I must put it on my husqvarna wr125
My TMX works really well. I liked it better than the Keihin. You have to do the o-ring fixes to the TMX or it will run rich. I have a video about it as well.

The china clones seem like a good donor for taking certain parts to put on the keihin
Yes. Except the slide.
it seems they didn't just copy, but also develop it
Wouldnt take much to polish up that slide though, any dings youre kinda sol but what can you expect lol
I tried using valve lapping compound to get it to mesh in there, wasn't working and didn't want to alter the Keihin slide to much.

My 01 YZ250 has throttle positioning sensor do these have that? Need one for my bike anyone have a link?
No, these don't but your bike will run without it.
Hie Gud Mrng. How much dose a Keihin 32mm PWK Carburettor and a 20pcs jet kit will cost in your country?
Carb is around $130 new. A lot of fakes out there Sudco has descriptions and pictures of real vs fakes on their website.
Where can I find a seat for a 38 PWK ??
A seat? Like an emulsion tube?
@@TepcoCycleRepair The needle and seat. I can find needles all day long but no seats. Jets R Us and JD Jetting don't carry them.
Sometimes called the float valve seat.
Oh got it. It's not a normally replaced part in the PWK it needs to be pulled and pressed back in. I would use a q-tip and polish, and polish the crap out of it. I use valve laping compound for bad ones and semichrome Jewelers polish for all others.
👌👍
the china carb in this video does not look like an airstryker. I don't see the two fins on the intake side like the genuine one has in this video.
You're correct, I used it in this comparison because It was listed as a 36mm airstriker.
How much is an original Keihin PWK 28?
$250-$275
I like how they take the slides and throw them in a huge bin during manufacturing, zero F's at that factory probably, although it most certainly a terrible workplace.
Cost difference in real and fake?
Around $250, they are $300 real or $50 fake.
Dude!!!! Back the camera up please! I couldn't watch but a quarter of the video. I was bending my neck and ducking down trying to see!🤣
they are both legit keihin. aftermarked keihin is dmp and is not marked also with brand keihin
If they were both Legit the slides would have been able to swap back and forth.
That is a blue needle bud.
Anche se ho un clone kehinin pwk 42 come carburatore, il kart va molto meglio rispetto al carburatore dell' Orto 39 a valvola piatta!!
Non sai mai se ne stai ottenendo uno buono o cattivo. I Sime sono ok e alcuni no
@@TepcoCycleRepair infatti però per ora va benissimo 😊👍
@@vincent1110377 Sec te se prendo un 21 pwk per 2 plus va bene? Percaso dopo un pò di tempo tende a scarburasi o rimane abbastanza stabile??
@simone dc devi provare :-)
They are called clones for a reason.
