Nice work! You are an inspiration to this 60 year old rider. Thank you!
Wow, thanks! My pleasure.
Perfect video! I'm getting into my old 04 crf230 and slowly rebuilding her. Got new plastics and tires but noticed when that carb just isn't working as it should. This would be much needed upgrade. So thanks!
Killer videos bro super informative for someone new to workin on bikes
Thanks!
Great information. Although I have a 250F I still ride the 230 a lot. This swap looks so worth the effort.
Thanks! Big bore 240 kit, cam, and porting is next. Should be interesting,
@@lowbuckgarage1 yesssssss
Your trying to turn a frog into a prince and loving every minute.
Think I'm starting to figure it out.
Maybe I'll get my 40+ year old XT
Yamaha out of storage. Will be watching your next race.
Nice upgrade!
Little bit of work but we’ll worth it as long as you at least have a pipe and opened up air box.
I use PE28 reamer to 30mm in my 230, pretty light carb, good responsive, and easy jetting
Pe28 reamer? Does it it have accelerator pump?
@@lowbuckgarage1 yes PE28(nsr150),it's 28mm but I made bigger hole into 30mm 🤭 (sorry pe28 reamer: I mean made bigger),no problem without accelerator pump, its responsive, no bog and wide power range, I'm statisfied with it.
I have pwk28 before, power is better but hard to find combination jetting.
so I come back to pe28, because it more reliable
PE 28 is 2 stroke carb from "honda nsr150 sp" its a famous carb... A lot copy of it 😅... Reamer meaning make the venturi hole have more bigger diameter just like over boring engine... And PE 28 carb doesnt have accelerator pump like crf230...
I've been binging your 230 videos now dammit I've got to go spend a bunch of money on mine 😀
By the time this video series is done I’ll have spent more time than money on it, but both are a sacrifice, depends on what your goal is I guess. I started with the least expensive first , but now I’m getting into some pricey engine work. I think the best bang for the buck was fork, shock and carb.
It’s still far less than a new CRF250R!
The goal now is top ten finish at world vet 60+ in November. We’ll see.
@@lowbuckgarage1 Mech eng / machinist here, I can't leave well enough alone. If nothing else it's fun to show up with a sleeper and start surprising people. I'm hoping to start racing this summer, never tried it before. Looking forward to your engine build vids. Kick some ass at Glen Helen this fall!
The fuel Inlet bits can be heated up and pulled out, they are a tight press fit. Some suitable loctite when you press it back in will keep it fuel tight. Getting a grip on it is a pain, but can sometimes thread a bolt in it. I see you got it later in the vid. Make it a nicer finished job when the lines fit
My elbow fitting leaked so I went back to original and dremeled a small notch in the frame, (running out of time) was not ideal, but effective.
Tortron, maybe you could do a how to on removing the inlet pieces.
@@RexRussell-ge7op il have a dig through my carbs and see if there's any suitable donors
Can't wait for to finish this build. I'm looking to do everything as you are. Was wondering what would be better big bore kit or high compression pistion. I haven't found a big bore kit that is both.
i just purchased a big bore 67.5 mm piston (237cc) from WISECO, it raises compression to 10.5. BBR makes one with even higher compression 11:1 but only 233cc.
@@lowbuckgarage1 thank you so much for the information
@OIF/OEF-0341 yes Athena is good too.
So on the needle you used the one out of the old factory carb, With the clip in the richest position correct? Your Information is so useful.
Correct, clip in bottom groove, mine is 2004 carb, so it has 4 grooves. Later models apparently only have 2. Ran even better that way. Thanks for watching!
hi, i have some question as i am doing the same mod. My first question is you says to dremal the intake boot. i noticed that the intake hole on the head is the same as the boot. How is dremaling just the boot helping if the hole diameter in the head is still the same. Di you do anything to the head side, or that side of the boot?
Next question. When i went to install the Carb, i had issues with the throttle cable where it attached to the carburetor. the throttle cable was not long enough when attached to the bracket and on throttle resulted in the carburetor slide being part way up. Did you change the throttle cable? or use the same 2 line one that came with the stock?
If you take the boot off the head and place it on the carb, then Looking through the carb towards the boot you will probably see a big lip between the carb and boot now, because carb is now bigger. Enlarge and smooth out the lip area to match, where the carb and boot join together, that’s all. Leave the porting of the actual head intake to the professionals. My head is at the shop now being professionally ported by a friend.
For cable: I had already removed my “push” cable for weight savings. I know several people who have done the same with no troubles, as long as it’s lubed properly. It now has plenty of adjustment at the carb.
Hope that helps.
@@lowbuckgarage1 Thanks!. the push link didn't look like it was doing much as there was slop in it each time i closed the throttle. However my issue was on the pull side. i ended up removing the throttle cable bracket compared the old with the new one and you could see where it attached to the cable link was further out. This in-turn caused it to pull on the throttle slide so it was about 1/4 open a zero throttle. to fix this i cut the bracket and just welded the connection point closer then re attached. i'm now trying to play with the fuel line where it rubs. I'm looking forward to seeing the difference once i have it running again.
Internals will wear faster with that much more power running through
So instead of a 30 year bike life, you'll get 28......
Exactly.
It’s a Honda, it will now live just short of forever.
Where do you route the 3 lines that come on with the carburetor?? Also how do you change out the fitting that comes into contact with the frame?
Also how do you delete your push cable. Mine is causing the throttle to get stuck
The 3 lines are just vent and drain lines so they can just exit out anywhere behind the engine, as low as possible, typically in front of the bottom of the shock area.
I had to find an L-shaped fuel inlet fitting on EBay, pull the old one out, (not easy) and press the new one in carefully. I’ve seen other guys just grind a smooth shallow notch out for the fuel tube on the frame, (not too deep) that works too.
The push cable shouldn’t be causing any problems, I was only trying to save additional weight at the time. I simply removed it, put a small zip tie around the rubber boot on the throttle cable to keep dirt out. Personally, I would just leave it on. Make sure the throttle, throttle cable, all carb pivots are lubed with light oil or silicone spray. Check the end of the throttle grip isn’t too tight against the end of the handle bar making it rub.
Good luck!🍀
@@lowbuckgarage1 thanks so much
Do you have a part number for the elbow inlet you installed?
A neighbor gave me the 90 elbow, but it promptly started leaking so I had to go back to the original. I dremeled out a small notch in the frame and used some thinner tubing which helped a lot. I haven’t been able to find one online yet.
Did you have any other mods before adding the carb?
Just aftermarket exhaust, opened up air box with TwinAir filter, CDI rev box.
I have been looking on EBAY for the CARB in the video, but none have looked the same. What year and model bike is the replacement for?
Here’s the link

@@lowbuckgarage1 thank you!!!
@@lowbuckgarage1 Did you have any other mods before adding the carb?
what do I look for if I want all those red caps and bolts????
I just went to EBay, typed in “CRF230F aluminum bolts”
Or “CRF150F aluminum parts, accessories” and saw many assortments of nuts, bolts, aluminum pieces available. Some are great deals, some not, buyer beware. Good luck!
I know you made this a while ago but is it possible to get more information on what you did about the gas inlet fitting?? Thanks!!
If you mean that it’s hitting the frame, First I just ground the frame a bit in that spot and used a thinner walled hose, just so it wouldn’t rub, It still rubbed just a tiny bit, didn’t really like that, so I scoured EBay and finally found a 90 degree inlet, pulled the old one out, pressed the new one in - much better. Use loctite so it won’t leak
Yes, is there any chance you remember any specifics on the fitting? I am going to do the same thing but can’t find a fitting. Also any advice you can give on how to switch the fitting over never done anything like that before.
Thanks for the reply!!!
@@thefarmkid1938 The fitting does not come out easy. I had to remove the carb, COMPLETELY DRAIN out any fuel, apply some heat, twist it out, it Will pretty much ruin the fitting by removing it, so make sure the new one will fit first. Good luck finding one, not that easy.
Easier to just grind frame a bit, it’s a strong area, just grind small area minimum amount needed. Use a strong but thinner wall fuel line. Good luck.
I appreciate the help!! you don’t have any way to find the part that you ordered I suppose??
@@thefarmkid1938 Sorry I don’t. but I do remember I had to sand off a lot of it with emory sandpaper to make it fit.
it looked kind of like this one:

pointing forward'' ??
Guess I should have said “stream pointing forward” down the port.
Does this have a 250 jug as well? Im having running issues with the bike i bought
It has a 240 kit. What kind of running issues?
@@lowbuckgarage1 the idle is all over the place, if i turn throttle to fix it the idle revs high then slowly comes down. Also spark turns black after running for few minutes
@@xxwastedyouth3391 Sounds like carburetor jet issues or possible carb boot air leak, Plugged pilot jet
DID U PORT MATCH?
Oh yes. You have to or it’s pointless. Just matching the carb boot to head intake is sufficient.
I did just get my fully race-ported cylinder head back from professional. Video to follow for higher compression bigbore, +porting, soon.
I just picked up a 2017 for a starter bike for my daughter and the factory carb was damaged by the previous owners. Do you happen to know if there's a Chinese clone for factory carb?
.
Or just copy you? Great videos btw!!
Oh yes they are plentiful on eBay.

Was this before or after 'World Vet'?
How did this years go? Video coming up?
Yes this was before world vet this year. I just got back. I raced both 55+ and 60+ crashed three times, worked my way back up to mid pack finishes in all narrowly missing a top ten finish. My best finish was 11th. Rough weekend. Video to come soon.
@@lowbuckgarage1 Wow, excellent.
I hope the you're healing up from
crash bruises. Great that you were
able to continue and finish well.
Did you feel like your machine was
much improved?
I have Trail Master TM250 (it's actually
223cc's) on the way, similar
to a CRF 230. I should have held
out for a Crf 230/250, but the TM fit
my budget better.
@@bikersoncall I checked out your TM250 I had never heard of it. your right, it is very similar except 5 speed instead of 6. Not sure about build quality compared to Honda, But Can’t beat the price!
@@lowbuckgarage1 Yeah, the build
quality won't be there I'm sure, but
the Zongshen engine should be pretty
bullet proof, and general durability
should be fine for what I'm doing.
Time for a camshaft upgrade ?
Absolutely. Just can’t decide. Web? Hotcam? BBR…
@OIF/OEF-0341 I went with the web 402. New Honda rockers. Larger intake valve.
@OIF/OEF-0341 still in build phase now but I’ll let you know, including video. The carb, pipe, ignition, air box was was a big improvement but now needs the bigger bore, cam, porting, to really wake the girl up properly.
@OIF/OEF-0341 Yes and no. Great Initial bark off the bottom due to accelerator pump, but slight loss of pull in lower midrange, but then better top end. Overall - much better.
Squish is a puzzle, all I know is higher compression works great on these motors.
XR250 never had a pumper carb. Am I missing something? Are you talking about the PD03a carb?....because that's only 28mm. The XR250r carb is 30mm, but not a pumper.
It’s Chinese clone of what I believe is the old XL250 carb, so you’re right I don’t think the Xr had one. But it definitely works.

@Low Buck Garage thank you!! I will give it a shot! Just wanted to say that your videos are inspiring! I was about to pay someone to rebuild the forks and I saw your video and decided to do it myself. Eventually, I want to do the fork swap but for now the rebuild will have to do. 😀
cab is type pe30？
PE30 carb does not have accelerator pump, the key to bottom end torque. It’s a clone of an old XL250 carb.

Hello friend. I have seen your videos for two days and I like them a lot, I bought a crf230 and it has some problems, I would like if you can help me solve them, how can I contact you to send you a pictures, please
What is the problem?
@@lowbuckgarage1 I put a pro tork 788 exhaust on it and it fails at high rpm, I returned the original exhaust because that's how it work better.
@@autoelectricobarajas8817 When changing to higher flow exhaust the carburetor must be jetted. Also make sure air filter, air box is not restricted.
@@lowbuckgarage1 Very well, which jet do you recommend? please
@@autoelectricobarajas8817 At sea level, with more exhaust flow and freer intake you need to go up at least 2 sizes richer on main jet, example: from 120 to 125. And at least one size richer on pilot from 42 to say 45. And move the needle clip down one position.
If you’re at high altitude, say 4000 feet or higher, you shouldn’t have to do anything. Something else may be wrong.
The hesitation would make this a
'pass' project for me. I don't see a follow
up on this project, if you've done one.
I did get it sorted out with a needle clip move and going up one size on pilot, it then ran great.
But now with all the recent changes; bore, cam, porting, I’m back to the drawing board dialing it in. More testing today. Currently editing the CRF150R fork install vid.
You probably said it right enough,
I'm not smart with Carbs, I have
no idea, why you would point
what ( I guess main jet shrugs) in
a different direction than it was
in, or how, or what it would do
differently for the bike. I also assume,
you might be putting 150rb forks
on the 230 , that will be cool.
I think the 230 is what I'm narrowing
my search down to, I just wish I could
get 25 hp out of the motor, vs what
stock which I think is between 12 and 17 hp.
The rest of the bike would probably
work for me, I like the simplicity of
air cooled, as well as adjustable valves
vs tedious shimming.
@@bikersoncall Given it’s inadequate suspension, the 230 is a great bike; six speeds, electric start, total simplicity, bulletproof motor.
The typical Amazon 30mm XL250 clone pumper carb shoots a quick squirt/stream of gas for a second when it first opens, giving the engine a quick boost from low RPM. Many times that nozzle’s stream will be pointed up, down or sideways, and not down the intake port where it belongs. It shows you how to check that in the video. Careful, that nozzle will turn and bend some, but it can also break off. If that stream isn’t aimed down the intake port you’re not getting anywhere near the full potential from the carb.
And yes I found some 2021 150RB forks on eBay.
@@lowbuckgarage1 Hey sir, what's the brand of this carb? I'm a little insecure to choose... Thanks!
