I Think I Fixed the Engine of this $1000 KX250

- I bought a KX250 for $1000 a few months ago. This is the third episode of the KX250 revival series, and in this video I rebuild the engine and resurface the cylinder to hopefully resolve the coolant leak issue I had before.

Thanks for showing the real struggle of working on old stuff.
Wait till the next video.. Linkage was gnarlyyyy
The jazz was spot on! It made me pour a glass of wine for breakfast 😂
Hahah I was laughing as I edited it, beating on that kickstarter to smooth jazz. Glad you liked it.
Love the content keep em coming !
Thank you!
Props for not giving up on that Kickstart lever! Even on my newer bikes after I've greased the splines with waterproof grease can still be a pain for whatever reason.
Music straight out of a Tyler Perry movie 😂
After a crazy morning in the ED. I needed this to calm down!
Thank you for sharing your amazing project. It’s very inspiring to see your skill set.
I'm glad you liked it, thanks for the comment!
Hahahah😂😂😂😂 i read the first sentance " After a crazy morning with ed

Let's gooo, welcome!
Ow, Didn't see you there, Alright Deadpool, Maybe pore the coffee on the kickstarter an give it a little energy shot
U did a lot of things that most ppl would do but would be embarrassed to show or get clowned on from the” I’d buy a new one or replace it while your there” type of ppl. Kuddos 🤟🏽
Thanks a ton I appreciate that
Broooo videos sooo satisfying 🔥🔥🔥

Great job!!!!!
Loving the channel Dude from the UK 🇬🇧
Thank you!
Omg im getting stuck nuts from now on dam karren and Kevin's 😮
that dang kickstarter, 3 hours. I could never. I would've thrown the whole engine in the garbage.🤣
Got it tho
Great channel man well done
Thank you!
Keep up the work
Thank you!
I just finished the full rebuild on my 2001 yz426f, I resurfaced the cylinder and the head the same way as you did saves me a hell amount of money, the crankshaft seized up and ruined the valves as well as the head, while I was at it I always wanted the head ported so I got that professionally done, bought aftermarket titanium piston and valves from wiseco, good valve guides from pro x and aftermarket cams from hot cams
I follow you and insta bro I absolutely love working on bikes, as well as you do 2 strokes are great and fun to work on.
Music in the beginning is so soothing
Yeah, if you like the soundtrack of soft porn.
@@jebediahnightlinger6357 it was a joke
@@dustinrichards8401 soft core porn is best viewed with a heavy metal soundtrack.
I have a 2004 kx250 and had a similar issue with coolant leaking into the engine. My problem ended up being the last owner didn’t put a head gasket it. Good luck with the bike! Those kx250s run great
Yikes! Hopefully I resolved mine. Thanks a lot.
@@KincadePavich hey when that thing goes up for sale if you're selling it I'm interested, I've been looking for a kx250
@@jordanshockley406 It will be for sale once I make sure she's running right and rip her a time or two. Where are you located?
@@KincadePavich Which of these 250's are the best, any tips? I'd like to get a 1996~ CR250 from somewhere (I'm a Yamaha DT + Honda CR fan) but I might be able to negotiate about a 2004 KX250 from a friend that I have ridden myself a few times too and I know the bikes recent history aswell. Hes having back problems and doesnt care to ride it so he MIGHT sell it if I offer some $$ :)

Nice video! Build/rebuild vids are my favorite. Me, personally, I would at least change the main bearings if the cases are already apart.
Certainly contemplated it. It couldn't have hurt, that's for sure. Although despite the crustiness, there really was no cause for concern. The seals probably would've been wise if anything, but I think she'll be solid.
@@KincadePavich I think and hope they will be ok. Fingers crossed and waiting for the first startup! Good luck!
Always put some packing grease on your Kickstarter lever. Preferably a high temp marine grease. Haven't had this issue since I been doing this.
Thanks for the heads up on Loctite. I spend a lot of money on that product. That won't happen again.
Absolutely, gotta spread the word!
Nice job
Thank you!
I will be trying stuck nuts thanks for the info
Awesome to hear!
I'm loving the jazz
Glad you liked it!
Not pulling out and continuing to beat it, interesting verbiage. Nice work 👌
You know I'm a wordsmith
i have 2 kx 250 engines 1992 and a 2001 both have fresh cylinder/powervalves if you ever need parts
Noted, thank you!
Keep up the good work mate👍🏽at some point are you going to be doing a full rebuild on a kx
I did one! It's the most viewed video on my channel. Here's the build: ruclips.net/video/CaNPxHTn3Ps/видео.html
Looking forward to this series. I have an 02 I'm looking to give some new life too. It's in great shape I'm just looking to give it some love and freshen it up while going a more modern route also. Loving this series so far 🤟
Awesome! Thanks so much!
I have some tempered glass for doing that. I haven’t tried it yet, but I hope that works better. I also have a small piece of granite.
Hey man great build . One thing I was curios about was on the pro x piston the rings that I got didn’t have a stamp indicating which was the top or bottom and I could not see a bevel , was yours the same way ? I’m thinking either ring can go either way ? Thank you if you decide to respond .
If a ring doesn’t have any indication then yes it can go either way!
I loved your content, your journeys as a dirtbike rider and as a self-taught mechanic blow my mind, It hits differently when you love what you are doing. BTW I sent a message in your email and I hope you can have some time to read it🤗
Thanks so much! Not sure if I saw your email or not, what was it regarding?
I emailed you again😊,
@@KincadePavich Hello Kincade just a video editor whose reaching out to you ☺
yessah!!!
I'm currently building a 2002 KX250. Nice video man. I'm hoping to find Plastics for 2003 and up. I don't like the shape of the rear number plates
I think you will have a hard time fitting 03 plastics if I remember correctly. I believe the tank and subframe design changed, but I'm not 100% sure. I also like the 03 and up plastics. Let me know if you make it work!
Good work - although I thought it was recommended to do a figure of 8 when rubbing the cylinder on wet and dry?
Also did you check the head for damage?
Good to know! Like I said, never done it before. I was just winging it, so I hope it works. Yes, the head is good to go.
I’ve Rebuilt 1000s of 2 strokes never once seen a cylinder warp, heads sometimes out a bit, but nothing a gasket doesn’t fill.
you should have put that shit in the record books or a museum.
Just fired it up, appears my fix worked!
wow! I never knew about why i found this plate. Use glass😢
What year is this bike??
I got Bob Ross vibes in the beginning
I’m in Colorado, what trails are they trying to close?

At least you keep your tongue in your mouth while wrenching, which is more than can be said for me! Keep up the great work!
Hahah, thanks Tom!
hahaha intro has the KX250 'make out' music bwhahahaha
Are there any articles or info on the Loctite thing? I could t find much.
Currently rebuilding a 94 KDX 200 and those used prices are tough so felt your pain on the kickstarter. Impossible to find a mf kickstand for a KDX that isn’t 200 bucks
I emailed Sean at Stuck Nutz to see if he has any specific info he can share, I'll get back to you! Morgan at Highland Cycles made a video discussing it as well, and said he looked into and confirmed all of it is happening but I didn't look into it more from there. Good luck on the 94!
Awesome man thank you! Been keeping up with all the builds, you do stellar work!🤌
Just wondering. You did all that strip the frame down. Why didn't you repair and repaint the frame?
This is not a full build. I'm doing some cosmetics but the overall goal is get this bike running and ready to ride ASAP. Bike wouldn't be done until Christmas if I gave attention to every component.
Why is it necessary to use glass under the sandpaper?
Perfectly smooth and flat surface
My dude have you thought about checking the squish after resurfacing the cylinder? Or are you confident there wasn’t that much shaved off that it would become an issue.
To be honest, I'm not an expert in this realm. Like I said, resurfacing the head was totally new to me. That said, it definitely was a *very* minor amount of material. That was part of why I was cycling the piston before I put the head on - to ensure it wasn't going too high on the cylinder. Realistically you are right, and this is something I should have done, but I think it will be okay. We will see!
@@KincadePavich I understand. It can still be done with the engine in the frame, though. Just put a small piece of tin of around 2,5-3mm through the spark plug hole. The correct squish clearance should be stated in the manual. Easy check, but a nice addition to your arsenal ;). Great videos, love to watch them.
Did you check the head to make sure it's flat
Yes!
Did you do a leak down test on it?
I did not
@@KincadePavich should be fine, send it!
Sheshh you beat your shaft for 3 hours?😨😨
A new record 🤣
@@KincadePavich 😂😂
What do you think of a 98 rm125 that doesn’t run for $1,400?
Personally, wouldn’t touch it.
@@KincadePavich ok thanks
You don’t know if the bearing or crank are good unless you test the runout.
Didn’t check the squish 🤦🏻♂️
Hey just found your channel and was loving it until Rihanna.
Rihanna slaps
First
Did your 6% female viewership go up since your last video?
7.8% in the last 28 days now hahaha
when sanding on glass you are meant to do a figure 8 motion to even spread the load.
Good to know thanks!
Love your channel. I was hoping for a sweet kx build but it’s going to be a budget build. You were doing so good there up until the Rihanna music. Come on man! But then you came back strong with the stuck nuts information. Keep us uninformed informed. Great job as usual.
Hahaha thanks for the comment. Rihanna has some bangers man. And don't worry, the CR is going to be all out once the KX is done!
@@KincadePavich we out here in internet land look forward to more content. Thanks.
