Destroyed KX250F Engine!!

"Bike runs good just needs carb to be adjusted"

[@rotax636nut5]

Wow you guys really know about great production quality, I had a look at Devin's channel and subscribed right off, that is some slick work right there!

[@blu3flare25]

Love the straight to the point rebuilds. You skip all the BS and get to the point, hard to find video's like this.. It makes me miss rebuilding my yz125 and cr125.. I haven't had to rebuild a engine since i got a kx250f.

[@ericnickel3280]

Any ideas on why the engine failed to begin with? Low oil, broken rod or piston? Oil looked pretty old. Lack of maintenance?

[@Kyegar]

Is this the bike I saw on Facebook that "only needs the top end" lol

[@HemlockRC]

Lol, top ends are expensive as hell anyway

[@TylerQueen213]

Not really my 2015 kx250f needed a top end just 2 weeks ago and it was only $250. Pretty cheap

[@carmane2894]

Tyler Queen that's a piston. Try replacing a cylinder and complete head. Or even just valves and cams.

[@TylerQueen213]

Carman E You May have read that wrong lol

[@TylerQueen213]

Wait nevermind I see what you’re saying. Yes I know but we were referring to a top end only. If you were to blow it up completely the total cost would be around $1200-$1500. At least that’s for my rebuild if I needed it done.

[@stephensanders4614]

when you see a "bling kit" do you know the motor is blown for sure ? :)

[@Booki89]

I really enjoy watching these engine tear down videos, do you think you will do one where you rebuild or put the engine back together?

[@CameronNiemela]

Thanks!! Yes, I'll be doing a bike build soon.

I have a kx250F 2015 and this week I change the piston, I love to see this video, same engine. Good video man!

[@CameronNiemela]

Thanks for watching!

[@joeishere500]

Gotta love those Blown-Up 4Strokes.... Good for Business 👍👍

[@biterbiber3865]

This engine reminds me of my ktm 525 engine(the damage was about 4000$ in new parts ). I rebuild it with a ktm 520engine and some new parts (only 600$ in total)

[@sparkie9947]

Would you reuse the cam assemblies on this bike if they look good or just replace them with new? Trying to save some $$. Thanks.

[@nomdeguerre13]

good stuff, always fun and informative. Guys, patronize the gent!

[@CameronNiemela]

Thank You!

[@brettnaylen9150]

I know this video is old but on my 2017 kx 250f I found 2 metal chunks along with a bunch of shavings so far and my mechanic friend thinks there from a thrust washer I haven’t opened it up to much but one of the chunks was in the clutch case and the other was in the black screen filter thing where they where in this video and I was wondering if you have had any similar experiences the bike runs fine but the clutch doesn’t work the best and from as far as I can tell there is not chipped gears or missing lugs on the clutch plates

[@demetriusbeasley151]

Hey Cam, I kno this video is kinda old but I was wondering.. is there a crankshaft seal that's suppose to go behind the flywheel on these kx250f's

[@kknn523]

If you can, please show what parts of the dirtbike wear out fast. Which parts need to be maintained so they don't wear. I saw a video that shoewed the chain wearing through the swing arm, and the linkage bearing

[@1sydman1]

its amazing you know where all the parts go and what they do

[@itaizrihan5701]

hi, i am looking for shell bearing assembly for crankshaft and not ball bearing, i want to learn the procedure, do u have a video of some engine with shell bearings? ty

[@stevenjam7119]

So as an engine guy obvs. Are 2 strokes really that much cheaper to maintain and fix in a bad case such as this kx engine? Im debating between a 250sx/tc or a 450f but engine work scares me.

[@TerrickHarden]

I'm really digging the background music.. And of course 2 strokes are king. I love 4 strokes too

[@CameronNiemela]

Thanks man!!

[@cameronmoslavac8547]

Wow nice drone footage dude!!

[@z-o-m-b-i-e-z4997]

Hi. First off all, you did a great job on the video and your imagequality and content are amazing. But i have one question: How did you manage to break lose the bolt which on the crankshaft at minute 6:42? Im am currently also trying to repair an old Honda 125cc motor and I also removed everything except this nut, because I do not know how to lock the inner clutch basket so that it does not move when I try to losen the nut. In your your video it seems like you could just hold the basket but that did not work for me. I hope you can help me and keep up the great work !

[@CameronNiemela]

Thanks for watching man! I used a Dewalt impact to remove the clutch hub nut.

[@Nolan320]

where did you get the magnet to pull the valve buckets out

Hey man where do u get your parts from live in st lucia an i need sum kx250f 2008 parts specially engine parts

[@don7406]

That sux the cases were damaged. Glad you could salvage alot of those parts though. We're those green inspection plugs stock or aftermarket?

[@CameronNiemela]

Yup, still lots of good parts left. I believe the plugs are aftermarket.

[@MotoMarv-Micahboy]

Love the part of the video when you bit the dust! And your helmet hair!😰 lol

[@msrx08]

Can you replace the single damaged gear? Can you save the main crank shaft?

[@MotoMarv-Micahboy]

I need some power tools man, I'm doing all my work with ratchets. Takes me a week what you do in one day!

[@MotoMarv-Micahboy]

Just got back from watching a few of your " big little brother" channel. Good stuff.....

[@novembersierra7333]

hey cam! i love how you have your blast cabinet set up with a pressure washer i would love if you could make a vid about it how you built it and were you got everything from. i have not seen one like yours and i would love to have the same set up. thx!

[@BRWfilms]

You had me like whaaaaa there at the end when you said you was going to try to get that motor running with jb weld 😂 i think its to late for that

[@garajulfaragaraj]

What is the history behind the failure? How many hours? How it happened? The good stuff 😂

[@Mxgarage33]

So are you parting this one out or rebuilding it?

[@CameronNiemela]

This one is being parted out.

[@chaytonruijsenaars3971]

i never been in a kx85, i have a kx125 2 stroke and it looks alot like that kx250 motor, water pump, kick start gear, clutch and all that look identical, if you showed me parts out of a cummins 5.9 or a 4BT or a cat 3304, 3306 or a C15 or a waukesha 330 or anything like that i would jump on it, those are the ones we mostly get, 5.9s and 330s out the wazoo from one customer runs locations but i rarely hardly ever get to work on bikes, sometimes i wish i could trade

[@mikeschlup5279]

You make a complex process look easy.

[@BrendanMX]

Do a video on all of the parts you have just show us around everything

[@bradgriffith6234]

Thank you Cam!!

[@tyhays6425]

Do you have extra valve cover bolts?

[@DuvidGuggens]

Hey Cameron can u confirm that 3, 4, 5th gear transmision sprockets are factory made weak ? on my crf250r 2008 they ever even from difrent steel or somthing even color is difrent and i never had to change anything else that 4th and 5th gear

[@CameronNiemela]

I've never heard of issues with them except on Suzukis.

[@DuvidGuggens]

u just pulled apart kxf250 trans check em atleast on my trx450 and crf250 and yz125 they are in difrent color

[@bradleyscott9436]

how do u know where all the bolts go, like do just remember or am I missing something cuz I would forget so easily

[@haydenpowell2555]

[@ducknorris9715]

I'm going to buy a 2007 husqvarna te510 any specific things I should watch out for?

[@DuvidGuggens]

dont buy it! buy 2 stroke because you are not rich if you buy crap and it blows on u get ready to spend 2x you paid for your husy. or buy gasket kit so you could inspect engine before you even ride

[@ducknorris9715]

Channel 8 I already have an rm125 but I want an enduro bike

[@DuvidGuggens]

get 2 stroke ktm exc300 or 250

[@CameronNiemela]

I'm not too familiar with TE510s, but check over the usual. Brakes, spokes, suspension seals, sprockets, linkage, cleanliness of air filter, etc. Biggest thing, if it's hard to start and it backfires on decel then it most likely needs valves.

[@brian_616]

u just ordered a wire harness for my crf70, throw in something for me i love your channel!

[@CameronNiemela]

Thanks so much dude!! I appreciate that, I'll have your order shipped out shortly.

[@MaxRay16]

With all the bikes you take apart, and parts that are trash. You could recycle the aluminum and just create ingots or custom casting. Not sure if you are into that but for my it is an interesting thing to do.

[@CameronNiemela]

That's a great idea but not something I'm really into.

[@edsonsilva8027]

Good evening? why does this type of problem happen in this type of engine? CRF also causes this. What do you do to avoid this kind of problem? Thank you

[@CameronNiemela]

This can happen on any engine that isn't maintained correctly. Change the engine oil regularly and replace wear items when they're due.

Cameron, let me ask you. So when you went to buy the bike, are their hints that the bottom end is shit? when you get hints like that, do you low ball the seller, So you don't spend to much? Do they usually get mad when you try to lower the price?
