can't believe I'm getting all this knowledge for free. this is incredible

[@jakerobbins5724]

Please don't stop making these awesome videos, I love watching them!!

[@CameronNiemela]

Couldn't do it without you guys watching and leaving awesome comments! Thanks dude!

[@EraZz187]

it's like porn :D

[@tommoss7716]

I’ve watched a couple of your vids now, fair to say I’m really impressed with your knowledge and attention to detail. Great work mate love the vids! 👍

[@rotax636nut5]

Nicely done Cam, smooth as an eel swimming in olive oil, loved the music score.

[@moto739]

Your videos are so beautiful man haha.. You do an amazing job!!! Have you ever worked for a racing team?

[@bikenband]

Rebuilt mine a couple years back and this video was a great refresher course. I went with stainless steel valves and never looked back.

[@JerryJrsGarage]

Awesome video! I like all the info at the ending too!

[@MrCalifornia1234]

I could do that no problem. Putting it back together - that’s another story.

[@shootmalones]

These videos are great, and you actually learn from them👍🏼

[@CameronNiemela]

Dude thanks for watching!

[@minasretifica2566]

Congratulations, my friend, for the mechanics videos.

[@evandowning2321]

Pretty peaceful videos my dude. Keep'em coming!

[@trufi18]

Man i appreciate so much your patience and effort to do this profissional grade kind of videos!

[@CameronNiemela]

Well I'm truly thankful for you guys watching the videos and giving your support!

[@adamalic6319]

Hey Cameron can you send a link to where you got your case splitter from thanks 👍🏽

[@rockbranchlaw7931]

So much knowledge and confidence to just take apart every component of the engine without hesitation.

[@CameronNiemela]

All comes with experience and just a love for wrenching.

[@murftupperware1012]

This is seriously going to help me out a lot! I just got a 2003 Honda CRF450r with a lot of work that needs to be done and a big part of that is it getting a valve adjustment and it makes sense now because I checked the air box and it was absolutely filthy and seriously in need of a replacement or cleaning

[@englishmotovlogs6542]

awesome video! love watching them, and great camera patience thats amazing, very slick.

[@CameronNiemela]

Thanks buddy! I do appreciate that.

[@microsoftteams2663]

Wow, Cameron, you do a great job videoing AND diagnosing. Kudos!

[@jeffloucks2120]

Your videos are therapeutic.

[@CameronNiemela]

Thank You Jeff!

[@1keykneedeep]

Thats alot going on. Starting to love the 2 stroke again.

[@nickj6275]

Not as bad as you think once you learn the 4 stroke it’s extremely easy to work on I can have my 250 down to nothing in 30 minutes

[@Steven-hg4cz]

Another great video with very nice editing and angles!

[@CameronNiemela]

Thank you for checking out the video!

[@kmonaso]

Great vid cinematography quality. Thanks for time and effor.

[@marccaya8412]

Good methods of disassembly combined with good video: well done Cameron!

[@CameronNiemela]

Thanks for watching!

[@jessegrimm9274]

I cant believe your self taught! That video was very helpfull. Keep up your awesomeness!

[@CameronNiemela]

Glad you enjoyed the video Jesse! I've had my fair share of learning experiences along the way haha.

[@viceanas9533]

Perfect rebuilt vlog

[@wadebenn4529]

Sick mate another build can’t wait 🤘👌

[@Jacare1973]

Nice vid. At the end of the day how much did it cost to fix it back to running?

[@burnrubber3361]

Cameron you got mad skills!! Kids don't try this at home unless you have a very skilled mechanic supervising..I'm serious the difficulty factor on this COMPLETE tear down and REASSEMBLE is a solid 9 out of 10....

[@lazn9863]

why the piston skirt was damaged? worn crancshaft main bearing?

[@chainhaded]

hi ,,air filter and oil filter its the same as honda 450?

[@mxrider2strokebraaap54]

Awesome video!👌

[@CameronNiemela]

Thanks dude!

[@p4pper256]

Cameron are there anymore videos of this bike? I seem to can only see 2 🤔

[@antonlords6]

Mad skills. Well done young man.

[@yellowveedub]

Cameron I like your videos man

[@TheTruckhuntervoges]

I need to learn valves and carb work

[@denwiessimo6088]

A compliment for not selling any useless crap in this video.

[@noah_rides8260]

Great video always learn stuff from them

[@CameronNiemela]

I appreciate you watching!

[@GoldensniperGaming]

Awesome video I love all the technical shots and explanations. You make it look so easy to work on a 4 stroke. I have a 17 ktm250sxf and will need to check valves soon.

[@CameronNiemela]

Thank you for checking out the video man! Best of luck.

[@betocabrer3239]

Excelente y hermoso motor ,igual que el vídeo,muy bueno!!!!

[@Mr.EeToMyself]

Sorry to bother ya, But I have a crf450r that seizes up a few moments after start. The kicker locks up and I can rock it back and forth to free it up... only for it to start and seize again?

[@kimbletrainer6058]

so if i grab the flywheel to see if there is any crank play up and down and side to side. will this give me an accurate read of the crank is okay? and can be used for the time being? obviously not new..

[@Justdirtbikes]

do the 450 and 250r have titanium DLC coated intake valves?

[@CameronNiemela]

I know the newer ones have Ti valves, not sure on the older bikes.

[@revhead9897]

Where did you learn all that you know today? Also, I'm in love with your videos, can't wait for those million subscribers you deserve!

[@CameronNiemela]

Thanks man! I learned mostly through experience and watching others working on bikes. Been taking notes since I was about 12

[@juanapalomino1669]

[@Booki89]

Sweet vid! Had no idea that valves can get like that.

[@CameronNiemela]

Thanks for watching!

[@joanllabres5599]

Great video, as always!

[@CameronNiemela]

Thanks!

[@dustin9035]

Did that ever get a transmission side oil change, damn, some of those parts looked grungy

[@upward_onward]

Man that was solid stuff.

[@alexguerrero3675]

I got a ? I'm finishing up my 07 450r build I had head port and polished 1mm bigger exhaust valves stage 2 cam 13:5:1 wisco new crank what is the best way to break it in

[@moacirmuniz1085]

Good afternoon from now I apologize if you write something wrong because I do not know English I'm brasilerio, I would like to know what oil, viscosity and ml you put in the inverted suspension of the CR 250? I bought this suspension soon I put it on xr 200 thanks.

[@topbananaprofit2238]

super skills! wow great vid!

[@JoranPrins]

I see you have green gaskets, but are they put on by honda itself or are they aftermarket? like put on not by honda. Cuz i have a honda quad, and the guy i bought it from didn't know if it ever had a rebuilt, so if the green gaskets are aftermarket, it probably would have had an inspection inside the engine.

[@CameronNiemela]

OEM Honda gaskets are usually green.

[@user-jf3eu7bn3i]

Good work 👏

[@mochagunglaksono1259]

I going to subs u because ure video is inspiring me a lot! Thanks..

[@lewisgilbert4769]

hi how did u know about fixing dirtbikes or get in to it did some one teach u or ... great vid as all ways

[@CameronNiemela]

I started working on bikes when I was 12 so most of it has come through experience. My family is pretty good with cars and that helps too. Thanks man!

[@nickchilds3104]

What an amazing video. I can't imagine how long it took you to get all those camera angles, especially with grease all over your gloves.

[@CameronNiemela]

Hey someone understands how much time it takes to film these haha. Yeah, it adds some time to the tear down but it's all fun. Thanks for watching man!

[@john21031]

Awesome video. But why not wash/wipe the engine a bit before disassembly?

[@Captainkirk88410]

Did you ever get back together an running?

[@H8er-Maker]

Nice camera work

[@rajmundkozak761]

professional equipment and workmanship

[@eugeniomartinmartin7404]

Wondefull video Crak!!

[@danieleross8776]

Great video man

[@CameronNiemela]

Thanks for checking it out!

[@emktm3482]

Hi, I'm looking for CRF 450 2010 on injection ? It is good bike ?

[@KHeidendal]

How much time did it take to rebuild that engine?

[@tomasnokechtesledger1786]

Nice disassembly!

[@scotthoover6689]

Is there a rebuild video?

[@user-hv3lh7jq2x]

great job

[@MrVinylJunkie]

Awesome Video, And Thank God For "Two Strokes" !!! :-)

[@CameronNiemela]

Yess! I love two strokes.

[@rbljackson]

So if that will be a complete rebuild, hoping you will show us the process as you go. Or is that one staying apart as a parts source?

[@CameronNiemela]

This bike is for parts only. I will be doing a bike build soon however.

[@ajman1999]

Great Job.greetings from Poland

[@CameronNiemela]

Thank You! I appreciate you checking out the video.

[@ajman1999]

Cameron Niemela I thank you for making such great movies

[@HybridEdits]

I know you sell plastics for bikes individually but what would you take for a full bike? Im working on my bike and want better plastics that arent faded.

[@joztunes69]

Try Ebay, much cheaper than retail

[@mitja8976]

Joz Sports Lets support his shop, your on his channel!

[@CameronNiemela]

Most of the time I don't have the full sets. Usually something is cracked or damaged.

[@timmwhite9218]

.....go to rockymountainatvmc.com or denniskirk.com, good plastics cheap and quick..... I've gotten UFO and Acerbis from both, good stuff and they came in 3 days. : )'

[@paulmullins102]

thanks dude

[@charlesbarbie17]

Im having trouble kick starting my crf 250r 2009. Takes around 20-30 kickstart. Any helpfull tips what will i do? Thanks mate.

[@CameronNiemela]

Valves are out of adjustment

[@arturoalvarado6969]

Muy buen video..i love the crf 450 Saludos d honduras...

[@stevennancythompson3674]

This is an excellent video. I really like your style. I do have a couple of questions that I don't know who to ask for answers so I hope you can help. I have a 2019 CRF450L and would like to detune it a bit for adventure riding. I already have a Vortec ignition, a heavier flywheel and a Recluse clutch should arrive tomorrow. Does anyone make a milder cam and is there a gearset available with a higher fifth and sixth gear. I've ridden motorcycles for many years but am completely new to off road riding and I'm 75 years old. Thanks!

[@hendriprakoso5102]

Love this

[@mijosipek5052]

could you say whitch part is what(just for the main things) on some video for us new guys pls?

[@wrenchone5003]

I was gonna say the looks of the intake side of the Piston you could tell it was lack of a air filter. Plus those stock valves are made of butter they are the weakest link .

[@CameronNiemela]

You nailed it, valves were pretty shot

[@paolodelborrello8619]

What year?

[@NandoRock88]

how are you? very good your videos, I comment that I have a Kawasaki Kx100 2014 and I am to realize the change of piston, I am not mechanic, but I like to do the mechanics to me to my motorcycle, some recommendation to be careful when doing it? Good Greetings from Uruguay!

[@CameronNiemela]

Hey Fernando! Thanks for watching. I would read through a service manual and check out lots of videos before tearing apart the top end. Unfortunately, I do not have any 2 stroke top end videos quite yet, but there's many good ones on KZbin.

[@NandoRock88]

Thank you very much for your contribution Cameron! I'm going to keep waiting for some 2-stroke video, you're going to have to go get some kx 100 haha

[@charliekay6400]

Could we see more full bike breakdowns? Love those vids

[@CameronNiemela]

Absolutely! I'll have another one coming out next Tuesday:)

[@charliekay6400]

Thanks, keep up the good vids

[@MrToolean]

Why does the factory use Phillips head screws? Seems like a bad idea.

[@danhpro5866]

use bosch go ?

[@josepelobmw]

Hi, I'm watching your KZbin videos, I have a Honda 450r 04 engine and I need the pounds of tightening, or where I can watch it.Thanks for the videos they are alluding me a lot.

[@kx250braap]

Take your middle name as a hint of what you should use lol 😂 but best bet is to get a service manual for that year should have all the torque specs

[@aleksanderkurilenko4588]

Nice job man How long this engine last? Is that worth to turn this bike in to dual sport or high maintenance will be a problem in the field away from the shop? Thnx

[@CameronNiemela]

There was no hour meter on this bike. These motors can last for dual sport though.

[@srpatnaik4548]

Brilliant Video

[@CameronNiemela]

Thanks!

[@Mattvxr333]

Only ever done top end stuff on engines never bottom, after watchig this video i think id tackle a bottom end with confidence

[@CameronNiemela]

Bottom end build aren't too difficult honestly, just take your time and watch plenty of videos.

[@cr250FoLife]

I keep having water accumulate in my crankcase breather hose on my 2014 crf450r. Any ideas? Thanks!

[@bronzenwoolsey7280]

Head gasket probably leaking

[@kweaver65]

Any tips for clean bolts? So many get stained

[@TPA_JW]

Try soaking them in some old gas for a bit, then use a brass brush on them. You can then always top it off with spraying them with some alum cleaner.

[@joztunes69]

WD40 can fix your stained bolts, and they will stay fresh and not get rusty

[@CameronNiemela]

I soak all my hardware in degreaser or solvent. That'll strip away all the dirt and grime.

[@tacticalmosquitoeater]

Naanak65 wire brush or wheel, wd40 and some CLR

[@endurotruckererniedesjardins]

Brake and parts cleaner them. If you want bling... pop into a truck stop and buy a polish wheel and jewelers rouge. Polish up the boltheads to a chrome finish

[@07STINKYBOY]

The needle bearing on the clutch had no washer on it unless it was stuck to the pressure plate

[@dustin9035]

Did the bike ever get an oil change

[@CarsnStuff]

soo awesome. I seriously get so intimidated with stuff like this. Like with car engines im fine. But when it comes to the transmission being inside with the engine its a whole different game.

[@CameronNiemela]

Dude thanks for watching! There's a ton of moving pieces but once you tear into them a few times it's not too difficult.

[@holeshotv311]

With all that damage to the Cyl. Wall, I would say someone was doing a poor job of servicing their filter.

[@joet6990]

if you don't mind me asking how much did you get the motor for? also are you selling any parts? my 2005 Honda crf450r motor needs a new bottom end

[@CameronNiemela]

This motor came with a whole bike I bought. Yes, all the parts are available on my store currently. www.revivemotoparts.com

[@joet6990]

Cameron Niemela alright, sorry for all the questions but what exactly would I need for the bottom end rebuild? I am just trying to have the parts ready and then ill have my friend to the rebuild

[@CameronNiemela]

There's many things that could need replacement in the bottom end. You'll need to have the motor completely apart to inspect what needs replacement.

[@joet6990]

how much do you think would be a good price for a shop to take it apart and check it out? i don't have nearly half of the tools i would need lol. my local shop told me it would cost $100 and hour just for service, how long do you think it would take a shop to take it apart, find the problem and put it back together? i just don't have much money to do this at the moment.

[@rezzgoatrising1829]

I just subscribed bro. Damn I miss my CRF450R. Had to sell it. Dang baby’s. I have to work.

[@CameronNiemela]

Thanks!

[@RussellBooth1977]

It's very easy to pull them down but it's a lot harder to put them back together if you don't rebuild a lot of them. The bore looks scratched right down the bottom of the cylinder which is a pain in the ass because I'd say it's Nikasil coated,to do it properly, the cylinder would need to be rebored & re treated. It seems to be the technology that even Ford have developed which is the plasma arc weld spraying technology which patent Nissan has adopted,it's similar due to the fact they use no cast or pressed in bore liners as such. The valves on the motorbike can be possibly reground & retreated with a titanium coating if economical or just straight out replaced. Shimming is a pain due to the fact the shims are a select fit & it's a matter of getting the right ones. The first of the Nissan R32 Skyline GT-R's used them as well as some of the Toyota engines. I know Nissan used them due to the fact the RB26DETT engine was classed as high performance when made but Toyota used them in the Corollas & Camrys. Wouldn't it be easier for Toyota to use hydraulic lifters in them? Their engines aren't high performance !!!!

[@montymanmontyman9832]

Never seen a crf450 wt such a nice clutch basket

[@compitamorales07]

The stator of a crf 450 r fits in 450 r ?

[@CameronNiemela]

450R quad?

[@jessarellanes6648]

good job

[@CameronNiemela]

Thank You!

[@Dvniemela]

She'll buff

[@CameronNiemela]

Dvniemela 😬

[@deadlyvenom9069]

is this ze brothers???

[@2strokin_it]

The valves wear like that normally due to the seat being a harder material than the valve. My guess would be that the motor over heated. Maybe the cooling system, or a lean fuel to air ratio occurred...

[@julianasilva-ih6fv]
