- The main purpose of this video is to show you how to remove, disassemble, and reassemble this carburetor. If you have any questions regarding tuning (what jet you might need, etc...), please refer to the numerous videos on youtube. You will receive much more accurate information if you do your own research. I do not know a lot about carburetors so do not take everything said in this video as the truth. If there is any incorrect info, please let me know in the comments and I will edit the video.
one of the better videos on these carbs. thank you
Glad you found it helpful! Appreciate it!
Recently purchased Hawk-250cc. I just wanna say thank you for your time, effort, and knowledge you put into this video. I'm technically a Noob in the dirtbike world, but I've built 2 from scratch with engine and frame being present and sold them and now I've put together this beautifully looking Hawk-250cc.... Anyways before arrival all the forums I read said WE couldn't SWITCH internal parts of Chinese/Japanese (not sure whichever but I'm not racist so I'll mention both 😅) stock carburetor😢!!! Then you came along and showed me the light🎉😂!!!! Keep up the good work,
Peace and Blessings
Great vid love the step by step , Mine gets here tommorow already have the 110 main jet , if you can find a small enough drill bit to take a little material from the pilot it will help with idle , been through it on a friends bike already.
Glad you liked it! I remember watching a video where someone had a drill bit set designed for jets. I might have to look into that. I plan on backing the fuel mixture screw out a little more and seeing if that helps at all before I drill or replace and make an update video on what worked for me. Thanks for the input!
That is what I was going to tell you Tex. I was told when you back that idle screw out it richens the idle mixture. This is the screw you have to get at from the bottom. You pretty much have to take the carb off to do it .
I used a .5mm drill bit from harbor freight about 4 dollars for the set. Thing is my drill would not hold it, so i put the thread end of the pilot jet gentle in to the drill and held the bit with a needle nose pliers. and it worked fine. No need to mess with the idle screw after boring out the pilot jet, i might go bigger in the future im still having to crack the throttle to start. but no choke so thats cool
That's great to hear. I'll have to give it a shot. Thanks for the tip!
This video definitely helped me out Wit watT I'm about to doI'm about to do Take my carbureter off and Tunein It is all stock 2020Hawk 250Hawk 250So When I started the bike does not idle The bike only stays running when I 1st started if I hold the throttle it's driving me nuts
It definitely should help with that. If you have any questions, feel free to ask, I'll help if I can. Motocheez is extremely helpful and much more knowledgeable than me about the subject.
How many mixture screw's turns from fully closed position
For best setting
Milage and pickup
The needle with multiple slots for the C-clip..... experiment with different positions it may be that the needle is sitting to low?Causing a finicky idle?.....The needle to low in the jet as the motor warms up the Jet expands from the heat letting just enough gas in for pretty good running and when the engine cools everything tightens back up. putting the choke on for a cold start opens the needle slightly over coming the problem for start up.... try raising the needle one level. the higher up the needle is off the jet means more fuel to the carb and vice versa.jim
Thanks. Very helpful.
What type of tamper proff screw did they use never get very good look at them.
IF going to order Jets what not get screwdrivers too?
I believe they used a regular screw and just ground the head off of them so we couldn't open the carb and tweak anything. I'm not 100% sure what you're asking in your second question. I believe youre asking if you could just buy screws to replace the tamper proof ones. If so, yes you can. I would suggest cutting a slit in them and removing them (same as in my video) and taking them up to your local hardware store (I recommend Fastenal if you have one) and comparing the length and threads.
great vid! helped me out a lot on my PZ30 carb, I seem to have a newer model because instead of tampering screws I have regular ones, also the mixture screw is much more easy accessable. I seem to run a bit rich, exhaust popping wildly while decelerating. Turning it clockwise is adjusting it to be more lean right? Because I hear not every carb has the same turning direction..
They may have made changes based on customer feedback? It's been so long I honestly couldn't tell you. Each carb (assuming the same brand and model) will be the same. Obviously, different carbs may not be. I would think a mixture screw is pretty universal in the way it works so they should be the same.
I've a 2020 model, and it has tamper proof screws too. Yours must be super new!
Will the fuel mixture screw have anybeffect on starting the bike? Im having to hold down starter for 5-6 seconds to get it started
Dremel works good to slot the screws too.
I had a dollar tree hacksaw, nope! Just have to find some replacement screws.
Great video! Probably the clearest, and most in depth video on this carb. Definitely a thumbs up. Made me feel more confident in mine.
But the idle is normal on these hawks. You pretty much have to warm them up, to idle at all. I'll be going to a stop sign, pull in the clutch, and hear some kid holler 'you stalled it!' Like no you 16 year old little crap. The Chinese don't like the cold.
Great job
hi, one question: did the gas consumption change when you add two spacer(washers?) on the needle?
Gas consumption like fuel mileage?
Please I’m in trouble my bottom line on the card disconnected and I don’t know where to put it back I’m loooking for the connection
Please respond if you know what that line is supposed to be attached to?
If it's the line I'm thinking of it's just a drain line. Make sure it's attached to the carb and just lay it over the swingarm.
What music where you using in this video I wanna use it for time lapse great video by the way
This sheng wey carburetor the pilot jet very hard to find, solution for me make a thread on pilot jet hole and using pwk pilot jet.
I've heard of people drilling out the pilot jet as well. Whatever works!
@@TexasMoto I already do it and it work fine, the most important thing is the idle not rough and can idle fine in low rpm.
sir, what is the diameter of the hole valve THROTTLE Pz30 , mine is broken. Pleas
Hardly a disassembly. You removed he bulb and replaced a jet.
Texas moto, I'm a tad bit confused with the ending here. the choke lever being all the way up isn't choke off??
+sshheeyy rides its been so long now I'm not sire I remember. I know that when I first got the bike I had it switched. It wasn't running right with the choke "off" but I really had the choke "on". All the way up is choke "on", all the way down is choke "off"
+sshheeyy rides my ending may be wrong. Ill double check tomorrow
TexasMoto moto I just had that same issue xD you were right. i too thought i had choke/carb issues but I wasnf xD i had it backwards too 😂😂😂
+sshheeyy rides haha! Glad you got it figured out
TexasMoto yep! but on the plus side, i swappes out the main jet to a 110. my bike cold starts all the time, no need for a choke. i thought itd ONLY run with the choke on. 😂😂😂 im glad thats not the case
whats the big screw sticking out the side of the carb for?
If I'm thinking if the right thing, it's the idle speed adjustment
@@TexasMoto I screwed it the whole way to the right and the whole way counterclockwise and it didn't seem to affect the idle
What size were the washers you put in there?
I wish I could remember. This was 3 years ago. Check out the Motocheez video on carb tuning. I think he may have mentioned it and that's probably where I got it from
where can i buy that type of carburetor
I'm having problem finding parts for sheng way carburetor
Upgrade to a mikuni and parts are plentiful. I honestly couldn't tell you how to get parts for the sheng wey. Chinariders.net has links to stuff so if you haven;t already, I'd check there.
So that small skinny tube at the bottom of carburetor cane off while I was riding and I have no idea were it is supposed to go can anybody help me out here?
If it's the tube I'm thinking of, I believe it is a vent tube. Just stick it in the bottom of the carb on that little nipple and lay it over the swingarm (straight back)
Maybe send me a pic on Instagram so I can make sure we are talking about the same thing @texasmotorider
Same carb on my atv im having troubles
Go back to 2turns, where u had it originally, now u know where choke position is
hey mate, i have the pz30 carb on my 250 quad. just wondering where did you order the jetting kit from for the carburetor? csnt find a jetting kit for this carb anywhere
A little late, could've sworn I replied so I apologize. If it's not too late, check www.hawk250.com and find where he posted the link to the jets. That's where I ordered them from. Again, sorry for the delayed response
Where did you find those jets?
amazon
What's the purpose of adding the two washers?
To raise the needle slightly. I forget to what benefit but I remember doing it. Go check out the motocheez carb tuning video for a better explaination.
well how it running now?
I sold this bike 3 years ago
so where is the tuning information?
Try reading the description there bud.
@@TexasMoto so it's not about tuning then :)
@@griffowolfhackmine No, it is about carburetor disassembly. It's been a couple years since I even watched the video but I believe I said something in there about going to someone else's channel to get tuning info. His video didn't show much of the carb disassembly but went into some detail about the tuning side.If you would like to get technical, I did mention the *tuning* I did to MY carburetor. I followed the suggestions in the aforementioned video though.
where does the hose on the bottom of the carb go
I believe it's a vent if some sort. I just laid mine over top of the swingarm
TexasMoto the black hose coming from the bottom of the carburetor? like the hose coming from the carb bowl
Yeah I'm 99% sure that was a vent. You can look at the manual and see but mine never was connected to anything
Hey. I know I'm late, but it's a drain. The screw on the side of the bowl, if you back it out, it dumps the gas from the bowl through that hose
What happens if you don't shim the needle? because that looks like the part that's the real pain in the butt
I'll be honest, it's been so long, I really don't remember. However, I do remember that it was not that bad.
@@TexasMoto ok, thanks.
is choke up off down on
down OFF, up ON iirc
worst music ever on a video showing motorcycle mechanic work.
Lmao. ¯\_(ツ)_/¯
Honestly I'm not understanding why you shimmed it .... Can someone please help me understand
Mr Bear it allows it to run more rich at 3/4 throttle. These Chinese clones bog at 1/2 to 3/4.
@@oxXHITMANXxo508thanks for responding..... That helped me understand. One more question.... Where would I find a couple of washer that small? The hardware store?
Really, no gas tank? lol
Thetathata Way not my proudest moment lol
