Congrats on tackling this yourself man! Info for future, engine oil recommended is 40 weight wet clutch comparable. I use Amsoil 0w-40 and change it once a year. To find true top dead center, remove that plug to the right of the oil fill plug. It requires an Allen bit. There is a T with a line next to it. That’s the timing mark. The valve lash definitely sounded lose, with the T set so your at tdc, both rockers have play, adjust lash to .005 or 5 thousandths with the engine cold. You’ll probably only do that once because it’s on the 500 hour service increment I believe. Unless you ride a lot🤣. Hope you had a fun summer on it and get in some good riding the rest of the year. Cheers.
I love my 250x I'm 32 and weigh 150lbs and 6'1 and it's perfect for trail riding. Although I will say on bigger hills in the trails you have to click it down to 2nd gear and if it's really steep down to first gear but I've had no problems with mine. I have put new diff bearing from all balls and all new wheel bearings in and changed the steering boot and she is mint. I would like an exhaust and new shocks because I don't like the squeaking it makes while riding in rough terrain.
Most ATVs need a 4T oil which has a friction modifier for the clutches. Straight engine oil will kill your clutch because it will let it slip. Also I'm going to replace the valve seals while I'm in there. Half the smoke is probably due to bad seals.
Soda blasting is a great way to clean up your oxidation or the white spots on your block. Our Honda 250 had bad oxidation and soda blasting worked great to clean it up. You use an air hose and blaster gun, then dump the soda medium (like baking soda) into the blaster and then pull the trigger.
I recently just got a 2014 Honda trx250x that’s been sitting and stripped it down to upgrade some things on it. As I was at it I buffed off some of the rust on frame and also the engine... does good job. I used a wire wheel attachment to an impact drill not as much force as a grinder with wire wheel .
If you use a wire wheel and aluminum polish and use tooth brush to put polish on and wipe it off with a microfiber cloth it will make it look brand new I just did it to mine.
Good video 💯 wish you showed the whole thing on how to set it to TDC and valve clearance having problem with mine took it all apart and changed the piston and adjusted the valves after but it doesn’t want to stay on the T mark in the flywheel and makes a ticking noise when I start it up
Mine made a ticking noise before and now after when I start it up, idk if it’s something with this year model or what. It doesn’t burn oil anymore though so that’s nice!
@@shaunmullins6126 I made a video on adjusting this valve lash on these quads. Very simply and straight forward. Go check it out! ruclips.net/video/oXAH3QzHHQY/видео.html
Get you a bottle of White Lightning acid. Wet the engine down with a hose, then spray it all over the engine. Wear a mask while doing this. Let it sit for a minute or two then pressure wash it off. That’s about the best way I’ve found to clean up aluminum. Don’t do it to many times, because it will start to make the metal bolts start to rust.
Not 100% sure about it on an atv but you can use alumibright not sure if that’s how you spell it but it’s for aluminum and that stuff makes it look new!!
Its one I found on amazon that doesn't quite fit so you have to use some tiger tape to make it work but it does make it sound like a bigger quad. The link for it is in the description if you wanna check it out!
I've had no issues outta this kit. Pretty dang happy with it. The only thing I had to do after the reinstall was make sure that my valve lash was correct. (link for that here: ruclips.net/video/oXAH3QzHHQY/видео.html)
Boss Adams, have you replaced the Gearshift Spindle on a TRX250EX? I have to replace one and not sure if I have to take the back of the engine off or if I loosen the bolt (part22) and remove the spindle. Thanks!!
Do you know if the NICHE rebuild kits for these are good. They are like $75 for piston and cylinder and gaskets and I don't ride hard so would it be ok?
I have heard of them but I have not used them myself. If I were to purchase a new one though I would go with this one amzn.to/3lIHeOr. This kit is a niche kit that has everything you will need to do the job. I had to purchase things separately, which was kind of a pain. I'd also pick up a valve lash tool as well amzn.to/3lNvPNr because it will need to be done once you do the repair. I will be doing a video here soon on the quad adjusting the valve lash to the proper mm and torque specs.
It is. Back when I bought it, it said it was for a trx250ex like I have. When I received it in the mail, the box was in spanish and it was clearly made for a 230 dirt bike but I made it work and it actually makes the quad sound really good.
The ticking noise is coming from the bottom of the case. I’m not sure what it could be without stripping down the whole motor. My friend repairs quads for a living and he gave me a quote but I haven’t been able to pull the trigger yet to let him strip it all the way down.
You definitely skipped one of the most important steps which is to show us how to put the piston rings on they have a specific orientation and nobody knows what you did
Is there any way to bore this top end to make it a 300cc or close to it I haven't seen anything and idk all the stuff I need I was hoping I could just find a complete kit
Lol its custom. Stock header pipe with a CRF 230 off brand muffler. I bought it when the company had it mislabeled for the TRX250. i just mad it work. Link to the exhaust if you wanna check it out: amzn.to/47vLw1X The header pipe doesn't fit but with some tiger exhaust tape, the midpipe fits just fine with the stock header. Plus it makes it sound like a bigger bike than it is.
No timing chain, I took pictures of everything I did step by step and put it back exactly how I removed it. The hardest part was setting the piston rings to the correct position.
Would recommend a new timing chain, oil chain and timing chain tensioner. Cleared all that clicking noise up in my moter.

Oh ya, it's a fantastic quad. I revived this one and made it run again. Cranks first press of the button every time.
Great video! I have a blown one in my barn that I’ve been hesitant to rebuild on my own. I might give it a shot now that I saw your video 🙏👍
Thank you! Glad I could help!

That's a good idea. I also stubbled across this stuff called aluminum brightener and it ended up working wonders.

As I was at it I buffed off some of the rust on frame and also the engine... does good job. I used a wire wheel attachment to an impact drill not as much force as a grinder with wire wheel .
I might have to give that a try! Any specific lubrication?
If you use a wire wheel and aluminum polish and use tooth brush to put polish on and wipe it off with a microfiber cloth it will make it look brand new I just did it to mine.
to clean it off you have to slowly move the pressure washer against it i have the same four wheeler and that helped mine
I appreciate the tip!
Napa aluminum brightner
So if your still wondering about the motor being like that I use meguiars hot rim cleaner and for the plastic get a can of sc1

Valve lash needs to be tightened. Sounds like ball bearings when it need adjusting
You skipped a lot of important parts what’s the point
Exactly .. skilled damn near EVERY important step

I appreciate the tip. I'll have to look into it!
hey great video what exhaust is that?? sounds good

Showed every thing but how to take apart and put together.
How i cleaned it on my 4 weeler is sandpaper
at 5:52 what are those little green things you have on the table? corner of the rag you have. i am confused on where mine go.
They are located under the valve springs. You'll need a valve spring removal tool in order to get to them.
15w40 Rotella t4 never had any issues
I run it in my 05 Recon 250 ES too. Same engine
I recommend a UNI airfilter if you need a air filter.
Yooo can u send me a link for a uni that fits a hobda 2007 250ex ? I ordered one that said it would fit but it doesnt
@@freedrugs4love Yeah no problem.

What size did you gap the piston rings? I have the Feeler gauge ready to go!
The Honda Manual will tell you to gap between .008-.012 inches. So if you check yours and it falls in that range, you should be good.
@@bossadamsgarage I’ve looked everywhere on the owners manual and I have yet to find the gap Size.. than you!
get a skid plate, my engine stays way more clean than before.
I'll have to look into that. Right now I'm pricing out a front end widening kit, hubs, shocks, and tires.
Looking for a kit for my 250 has this kit held up i will pay extra for the honda parts but really dont want to
I've had no issues outta this kit. Pretty dang happy with it. The only thing I had to do after the reinstall was make sure that my valve lash was correct. (link for that here: ruclips.net/video/oXAH3QzHHQY/видео.html)

Is that exhaust off amazon for 90 something dollars I been looking for my 01 trx250x.
It is. Back when I bought it, it said it was for a trx250ex like I have. When I received it in the mail, the box was in spanish and it was clearly made for a 230 dirt bike but I made it work and it actually makes the quad sound really good.
how did you set your timing after you finish installation?
I just made sure when I put the new cylinder on I had the piston at "eye balled" top dead center.
It’s been about a year now, how’s that top end treating you? Quad still running great????
Most reliable quad I've owned!
Alright buddy well I just ordered the top end rebuild kit that is in your description so wish me luck boss!!
Is that ticking a loose bolt somewhere or did you forget to adjust the valve lash?
The ticking noise is coming from the bottom of the case. I’m not sure what it could be without stripping down the whole motor. My friend repairs quads for a living and he gave me a quote but I haven’t been able to pull the trigger yet to let him strip it all the way down.
No indicator for TDC on the piston? You just "eye ball" it to the top position?
That’s what I did, I made several rotations and paid attention to where the piston maxed out at before it went back down.
Can I have the old cylinder?
I would give it to you but we’re keeping it just in case bc we actually own 2 TRX250EX’s
I never saw you wash the cylinder with soap and water ? I has always told to do so as to remove all the reminding filings from machining/boring/honing
Learn how to talk
What you can do with those plastics is put some wd40 on them they will look so much better
I will definitely have to try that. I’ve looked at buying new plastics but I can’t see the benefit in spending the money.
You definitely skipped one of the most important steps which is to show us how to put the piston rings on they have a specific orientation and nobody knows what you did
If you look at 5:23 in the video, I posted a diagram on how the ring orientation should be.
Is there any way to bore this top end to make it a 300cc or close to it I haven't seen anything and idk all the stuff I need I was hoping I could just find a complete kit
A local shop might be able to get it done for you or there might be some kits online, however, I haven't looked into it that much.
What exhaust is that?
Lol its custom. Stock header pipe with a CRF 230 off brand muffler. I bought it when the company had it mislabeled for the TRX250. i just mad it work.
Link to the exhaust if you wanna check it out:

Can you provide a web address or information on the of your supplier ?
I actually found what I needed for a decent price on eBay. All the parts came with it. Not sure If they’re still a seller but I’ll check for you.
@@bossadamsgarage I found it on Amazon. Thank you
Did you have to remove the timing chain? How’d u set timing marks
No timing chain, I took pictures of everything I did step by step and put it back exactly how I removed it. The hardest part was setting the piston rings to the correct position.
Push rod motor so no timing chain. About to take one apart over on my channel. Still diagnosing issues on it. Come check it out.
@@GrowYourOwnFun It uses a timing chain to drive the camshaft that has cam lobes which push the pushrods up and down

Would be very nice to see you actually doing it instead of just saying how you did it..
Is that the same engine as the honda recon 250?
I believe it is. I know that most of the parts are interchangeable.

I appreciate it! I’ll give it a shot! Will it pit the metal at all?
