- HAWK 250 VIDEO LINKS
So all the links that were promised are below, here is a quick little blurb on my hawk 250. 4,778 miles at the time of this video, my hawk is a 2019, it has a 110 main jet. Has lots of improvement mods, but no performance mods. Everything I have done to the bike has been documented here on RUclips, check out my hawk 250 playlist below to see everything I’ve done to the bike! There are also lots of hill climbing and riding videos in the playlist as well.
At the time of filming this video I had
Miles: 4,778
Hours: 159.0 (keep in mind I put this hour meter on the hawk at roughly 375 miles)
AIR BOX MODIFICATION VIDEO: coming soon
Here is the link to the top end from eBay, again i recommend buying factory parts. Although this top end seem fairly decent other than the few things I pointed out in the video: www.ebay.com/i...

Hey just wanted to thank everyone for all the love and support! Here are a couple videos that should be watched in series, these videos are absolutely critical to the longevity of the hawk 250. As you guys know the rings got toasted on my bike because of the air box, these videos go though the repairs as well as the proper modification of the air box to prevent engine failure in the future. As always, thanks for watching!

Can I put a CG 200cc big bore kit on a CG 150cc engine? This is a push rod motor than I'm trying to do this on. If so, is there any kind of modifications that I'll have to do to the case?. Please help @goodol'boys
@@williebeats4921 to be honest I’m not 100% sure. You would have to do some research. Iv never done a swap on one of those
You might not get a bunch of views for this but I greatly appreciate it, sir
Hopefully I get a million views. Thanks for watching!
@@goodolboys713 i hope so too good luck
@@goodolboys713 Maybe add some typical Dirtbike tags idk how its called properly, that maybe will help growing a bit. No hate all love
First rate video clear and concise. Been looking forward to this video and it didn't disappoint. Very well done. You're a good communicator.
Thanks so much! I really appreciate the complements, I try my hardest to make things as clear as possible so everyone can understand. Thanks for watching!
Nice job on teardown and rebuild and explaining step-by-step wolf to do never seen a video that was step-by-step Baylor fast-forward through something or don't show you how it come apart and it's so aggravating your video was absolutely perfect
Very good video, you answered a lot of questions I needed to know the answers to. I have been thinking about buying a hawk 250 DLX for a long time now and seeing as how easy and cheap it is to rebuild one has convinced me to bite the bullet and just order one. Thanks for the encouragement.
My friend you are the best for take the time to create of video. I would like invite a coffe beer or do you like because was a placer watch ed the video....I don't know if I ready to rebuild but I love of the tutorial. Regards big hug .
Thanks for taking the time to record the process. You rock.
No problem, I’m glad I can help out! Thanks for watching!
Great video, thank you bud! This is so valuable since there is no shop manual out there for this bike. I can tell you have worked on lots of different bikes, and applying that experience here.
Reusing head gaskets, for years and years my dad and i had used over and over lawnmower head gaskets, we just cleaned them, painted with Hi temp paint, usually white, but anything will work, we used gaskets that outlast two lawnmowers, about 20years, and the gasket and engine was still good!
Amen, a lot of people don’t understand this. I grew up doing the same thing with the lawnmower engines, and had the same results. That’s where I got the idea from LOL. Figured I would try it on the hawk, so far I have almost 1000 miles on the used head gasket with no issues LOL. Thanks for watching
i never like a video, but this guy deserves it
Haha thanks!
I see you from around New Orleans I live about 20 miles west of Baton Rouge by little town of maringouin watching your videos of the hawk made me order one two days ago can’t wait for it to come in I injoy watching your videos keep it up
Great job. Enjoy the video I watched the whole thing. I would like to say that I just purchased the same bike it’s a 2015 model it’s got 5 miles. it was used. Clean title got it from an older lady. She said it was her sons. He was too scared to drive it. So I change the spark plug change. The battery does not turn over. By the way, there was a little water inside with a spark plug was at. What should I do take the top and a part and reassemble. I’m pretty handy with lawnmowers the stand on ones as well as the push ones and then walk behind. Thanks hope to hear from you soon.
Water in the top end is never something you want to see, however it does happen. More than likely it’s probably just moisture from
Sitting, my recommendation would be to put just a little bit of oil down the spark plug hole and turn the bike over with the starter. Make sure that your spark plug is not in the bike when turning it over and clearing the oil out. Once that is done re install the spark plug and run it. It should be just fine. Thanks for watching!
I think you can bore the case and run a big bear 350 top end. It would be like 500, but that bike doesn't owe you anything, so if you could get more use out of it for that.... Also they got inverted front ends for less than 200.
MAAAAN ITS GOOD 2 HEAR SOMEONE WHO KNOWS.. WHAT THERE TALKING ABOUT.. ESPECIALLY 2 UR AVERAGE JO..
Just figured I’d share my wealth of knowledge that’s been gathered over many years. Thanks for watching!
The Denco iridium spark plug had to replace my Spark brand spark plug because it is best to have a lot more resistor resistance in the spark plug and if you don't have the right modified the electrical system then the stator coils magneto was all burn up because I ride fast. The new stator coils had replaced my Hawk 240cc then it made glad that it run good after I sand off the black paint off from my twin tube cradle and my mount of no rubber bush to my engine crankcase block has much better ground. The new alternate type magneto is charging my Battery. Before it didn't charge and it pull me off in the middle of the road.
Greetings from Corpus Christi Texas
Heck I havd scuffed the rings, and the jug, in engines that burn oil like that and all was good, i mostly just scotch brite the rings to clean them, then just 220 grit sand paper to scuff the jug, and it was good to go! And it stopped smoking!! I was totally expecting it to smoke, but it was like new, again!
Heck yes at work send it!
You a bad man ill get there fell off it today. Its strong bike. Worth fixing 👌 👏 👍
It’s a great bike! And very strong, lot of people don’t give the hawk credit that it deserves! Thanks for watching!
I bought a 125cc engine off ebay n put it on a 70cc honda frame, it has held up great with no issues, so I feel safe using ebay parts
There is definitely some very good stuff on eBay! I wasn’t really worried too much about using eBay parts on the ol hawk, after all it is from China too lol. Thanks for watching!
I think someone should buy one of these bikes and do all the prep with the electric grease loctite etc put a ton of miles on it and keep it maintained as cheap as possible like your saying re using the jug and piston to show how little this can cost
Yes sir! It’s really surprising what you can get away with on a basic bike like the hawk. I am more or less trying to see how cheap I can get by with my hawk. It’s kind of hard to do when it gets beat on and ridden through mud and water all the time 😂 a lot of people would call that abuse, I call it riding 😁. Thanks for watching!
I’m doing that very thing myself. Over 4000 actual miles thus far and still no problems. My Hawk is my daily commuter.
That was extremely insightful. Thank you much.
Thanks for watching!
Good morning. I just installed the 300cc big bore kit and the bike is smoking horribly. I took everything apart and the only thing I noticed was the little head dow pin rubber seal was nipped. I'm guessing that little rubber is heat resistant. Correct? Also that would be a cause of severe smoking. Worse than a 2 stroke. Do you know where I might find a replacement....thank you. Great videos btw
Hope I get this many miles outta mine just got the dlx
Newbie question perhaps but... How does oil get to cylinder walls, splashing, oil vapors? And what kind of oil pump this engine has?
Great questions! There’s a couple ways cylinder walls get lubed, just depends on the engine design, there is a thing called a oil squirter, it looks like a big fishing hook with a small hole in the end, it physically squirts oil onto the bottom of the piston and cylinder walls. Another common way to lube the cyl is a oil fling, oil can be flung off the crank shaft, a lot of times you will see a oil fling on smaller Briggs and Stratton rods, it looks like a protruding pice that hangs from the bottom of the rod. I’m not entirely sure what kind of oil pump the hawk has but it’s more than likely some kind of gear pump.. thanks for watching!
Great video , very informative and very easy to understand.
Good instructions man!
What about adjusting the valve clearance using the adjusters on the rocker arms? Surely there is a factory-specified clearance that needs to be set for both valves. Did I MISS that step in the video?
Great question! Yes, the valves absolutely need adjusted after any kind of top end work, as mentioned in the video. I have never made a full in depth video on adjusting valves. The manual says .02 thousands for intake and exhaust clearance. There are videos out there about adjusting the valves, it’s a very simple operation. Hopefully this helps, thanks for watching!
I have a question. Please, inform the Great motorcycle Hawk 240cc cruiser 2023 Enduro Screamer just like your color blue Hawk 240 motorcycle. I think a lot about 19 inch rear tire for cheap Shinko and street spiked wheel and replace the original 18 inch wheel. The Kawasaki sports bike have the aluminum rims color black and he put them on His black motorcycle Hawk 240. I watched it in RUclips. Where with my Honda front fender aluminum alloy but I had to drill 4 more holes and finally the Honda fender color black fits to my forks.
Always use 91 octane and or 92 octane and at BP you don't need ethanol additive so it called Silver 90 octane pure gas for the HaoSen Hawk 240.
Awesome. I was gonna get this but I got the orion rxb 250l instead. I love it so far. My buddy that I ride with has a hawk
Sweet! The Rxb looks like a mean bike!
@@goodolboys713 it's not too bad. I've got the 250 and I got the 150 for my ole Lady and I honestly prefer the 150. It's a lot quicker and lighter. Is that hawk running fine after rebuild?
@@mototoad1242 interesting findings! The hawk is running superb after the rebuild! Thanks for watching!
Can I put a CG 200cc big bore kit on a CG 150cc engine? This is a push rod motor than I'm trying to do this on. If so, is there any kind of modifications that I'll have to do to the case?. Please help @goodol'boys
What's the stroker Cam called?
That would be a great question for oddballperformance, he’s here on RUclips. He did a performance cam in his bike so he know quite a bit about all of that. Hopefully this helps, thanks for watching!
Sweet video🥰
Do you have a video where you show how to properly adjust/check the valve lash? I just bought a magician and I need to check mine and you kinda skipped the how-to for that part 😅
I touch on adjusting the valves briefly in this video: ruclips.net/video/kfPcoDOZSgE/видео.html there are many videos on RUclips on how to specifically adjust the valves so I haven’t done a video on it. I suppose at some point I should lol! Thanks for watching!
Great work nice and clean not a bad bike for the price Cheers Mick Australia.
Leasen every one I have this engine on a home made frame. So I have to take motor off the frame just to get the valve cover off. My question is what is the best way to adjust values and do I need to give any kind of cap or just touching or snug the adjustment bolt down on the valve. Video would be great. But any explanation is going to help. Thanks
Great video
my exhaust gasket was fucked out the factory had to replace it immediately i’m surprised it even sealed. only took my exhaust off to adjust my clutch
I love this!!! YES!!!
Thanks!
Thanks for the video! Where did you get that rear tire? Can't find a 17" anywhere
Mine is actually 18” you might want to double check your rear wheels size. normally off-road rear dirt bike wheels are either 18 or 19 inches. From what I understand the weird sizes like 17” and what not are normally for more onroad-ish tires. Your may need to swap rims if your rim is truly 17”. Hopefully this helps, thanks for watching!
Ok thank you for your reply. But yea its 17" any idea where I could find a 18" wheel thatll fit?
@@channinbell8070 txpowersports can get you a factory hawk wheel, or the better option is to get a used Japanese wheel off of eBay. Your looking for an 18” that’s about 215 category wide (really you can pretty much go with any almost any width rim here, just make sure it’s not obviously too wide) the most important part is to make sure it has the same amount of spoke holes as the hub on your bike (you may need different length spokes but those can be bought and upgraded as well. Hopefully this helps, and thanks for watching!
I have a question what would be the interval for the cylinder block, piston and rings need to be replaced. I've got 13k miles lifan 250 same cg250. Wonder if they need to be replaced as they have never been replaced since I bought the bike.
Where can one find answers to questions about the TBR7?
Hey man by chance could you let me know where to find torque specs? I could really use them…. Also when assembling the bike, should there be a certain torque for the axles?
Best thing to do for torque specs is to look up bolt size, there are certain tor specs for different bolt sizes. As far as the axle bolts, it’s something that I just feel out, it’s hard to explain really, but I tighten my axles decently tight, but not too tight.
Hey can you help me . I need a crankshaft for my 2020 hawk can't find one
That’s a great question, it’s not something I have found a source for unfortunately. My best bet would be to ask txps for one
Bro is this dsame engine with the csc tt250? Or cg250?
good job👊 so is your hawk still a 229" or 249cc
It’s still a 229. Although both jugs say 250, neither is bored out lol. Thanks for watching!
Very informative video.
Thanks!
Do you know how to look for the cilinder head for the hawk on ebay
So there is a guy under the name hawk250parts on there and he is your best bet. He’s really good with selling individual parts for the hawk. Otherwise you will need to go to txps. Hopefully this helps, thanks for watching!
I jus did this and my bike wont start and if it does it bogs really bad. Help?
Best way for me to help you is to recommend watching the video very carefully, make sure you did Everything correctly. Go over it with a fine tooth comb so to speak. Pro tip, the problem is something to do with the work you just did to the bike. Hopefully this helps. Thanks for watching!
what is the spark plug you are using in there the d8rtc doesnt come up at any auto parts stores around me the one i did get from one that was ngk doesnt look at all the same size wise im not sure which to get if i needed one in a pinch from a store
i ordered 8 online for 15 dollars so i mean im good for a long time but im just curious for in the future
That’s a great question! I will have to look at my spark plug. I am running the factory the spark plug. These bikes are 4 stroke as you know, what most people don’t realize is that the spark plugs are good forever (100,000 miles or more just like on a car) it’s very hard to wear a spark plug out with normal use, normally what happens is the spark plug gets damaged from dropping it or some other incident like that lol. Hopefully this helps. Thanks for watching!
@@goodolboys713 yes the dropping it or something may be how it was damaged.. -_- the starter switch button as well >=|
@@cybexemoto6575 it happens to the best of us, keep on bikin’! Thanks for watching!
How do you know if you need a top or bottom end build? Wouldn’t it be cheaper just to buy a new engine on ebay? I loved my Hawk because of its ease of working on. Thanks!
It’s really hard to put into words the symptoms of top or bottom end, once you have so much experience it’s really a sixth sense. It is far cheaper to replace parts in an engine especially if you can do the work yourself. There are exceptions to this, if the entire engine truly needs rebuilt or has serious issues beyond reasonable repair, sometimes it is more cost effective to replace the entire engine. The hawk is a rare exception, it’s unreal that you can get an entire engine for $500. Most engines for motorcycles, dirt bikes, and four-wheelers are upwards of $4,000-$5,000 and up depending on what the engine and unit is. I agree it’s a very easy bike to work on, that’s probably the best part of the bike! Hopefully this give you some insight, thank for watching!
Thanks for the reply, you should have way more subscribers and views. I sold my hawk for a KTM 390 ADV. Awesome bike but if it broke down I wouldn’t know where to even start. With the Hawk I learned to change the oil, brake pads, adjust the chain and adjust the valves. The Hawk 250 soul and I think motorcycle power is way overestimated.
What did you set the valve last at
Factory specs
do they make a good quality big bore kit for the 250 hawk. Or a 4 valve head kit.
Unfortunately I’m not really sure, I have not really looked very far in an aftermarket for the hawk. I’ve heard that boring out the cylinder (big bore), actually causes overheating issues and he dissipation issues things along that line. Thanks for watching!
what wood you suggest, when i put my front brakes on it shimmies
Sounds like you may have a warped rotor, I would ride it for a couple hundred miles and see if it goes away. If not, jack your bike up and spin the front wheel, watch the rotor as it spins and see if it wobbles. Hopefully this helps! Thanks for watching!
What’s the difference between this motor and a 250 Honda rebel?
There’s a good bit of difference but at the same time they are some what similar, kind of two different machines at the same time as well lol. Thanks for watching!
That was a good instruction.
Out of curiosity does anyone know what the cylinder pressure should be on a compression test?
Also, where can I find the torque specs for the bolts?
If I remember correctly, anything above/around 90 ish psi for compression is good for the hawk. It runs like a top at 90 psi compression. Torque specs for the hawk are measured in uggaaa dugaaasss, there have been no torque specs that I could find for the hawk other than for the head on the forums. You have to use your best judgement and experience to torque your hawk bolts. Thanks for watching!
Wondering about doing a big bore hawk, there has to be parts out there
That’s a great question! Iv never really looked into it, however I have heard the hawk does not react well if you bore it out too much. Thanks for watching!
its out there remember its a clone.
For the same price they sell a 300cc jug/piston kit. 👍
Man I bought a torque wrench and mine only goes to 20. I can’t get away with only tightening them to 20 ft pounds can I?
Edit: there is an parts store in my town so I can’t just go get one
I mean spoked rim 19 inches. Computer did misspell for rear swingarm
nice vids
Amazing it's not overhead cam.
Most of the parts on eBay are from same factories that make the engines.
Seems like the jug I got was genuine, who really knows lol, if they are original factory parts they certainly don’t put the same quality into them! Thanks for watching!
@@goodolboys713 From what I have seen Zongshen makes parts for many Chinese bikes.
@@Random-ed2xf that’s good to know, more common = easier to find
Questions and answers? Who has any?
Oil gallery not galley
Your wrong. It’s oil galley, look up the difference.
@@goodolboys713 I have. A galley is a kitchen on a ship. A gallery is a long narrow hall or passage.
@@DoRC you go to a gallery to look at art. Please Look up OIL GALLEY before you leave any more comments😂
@@goodolboys713 words have multiple meanings. Seriously Google it.... Even if you just Google oil galley you're immediately corrected to oil gallery the first few results. But if you Google oil galley or gallery it's explained on several sites. Also if you look at the definitions of the two words the third or fourth definition of gallery is a long hallway or passage. Nowhere under the definitions of galley does it say anything related to any sort of passage. I'm a professional mechanic with over 30 years of experience and I've been through this many many times.
@@DoRC lol! Mechanics are not normally literature experts. I have over 23 years of mechanical experience, Iv had plenty of experience of all kinds of mechanical bologna over the years, it’s all I do. Can you call it a galley or gallery I think either way you want to say it is fine. I’ve looked it up it looks like the definition for both words are exactly the same. It’s personal preference. I like the way galley sounds more than gallery. Galley sounds correct to me when set allowed. Again in my opinion it’s totally up to personal preference.
Anyone notice at 20:20 the color of the connecting rod, blue on the small end, where the piston goes, most likely has a shot out bushing that the piston pin goes thru, Mr. shade tree mechanic didn't notice, most of these guys only think they know what there doing, re using the head gasket and all..
