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
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....
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..
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?
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
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.
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.
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!
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.
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
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 .
Hi, I'm watching your TH-cam 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.
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.
.....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. : )'
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
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...
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
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.
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!
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 TH-cam.
Cameron Can you please Answer A Question i got? If a old 2stroke "cuts" the cylinder and the piston gets stuck cuse oil pump dies, and the bike gets put in a barn, from 1989, whit all fluids as usual still left inside... What Happends whit bearigs the crank the metal the brake systems, the gasoline, the oil? dose things break? bearigs wear out? Tnx For Answers
The biggest issue is the fuel. Once it sits it will gum up the carburetor and destroy the seals. Bearings should be fine if there was grease/oil and no water entered. Of course flush out all the fluids including coolant, brake fluid, oils, etc.
can't believe I'm getting all this knowledge for free. this is incredible
Please don't stop making these awesome videos, I love watching them!!
Couldn't do it without you guys watching and leaving awesome comments! Thanks dude!
it's like porn :D
I could do that no problem. Putting it back together - that’s another story.
Rebuilt mine a couple years back and this video was a great refresher course. I went with stainless steel valves and never looked back.
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! 👍
So much knowledge and confidence to just take apart every component of the engine without hesitation.
All comes with experience and just a love for wrenching.
A compliment for not selling any useless crap in this video.
Your videos are therapeutic.
Thank You Jeff!
These videos are great, and you actually learn from them👍🏼
Dude thanks for watching!
Your videos are so beautiful man haha.. You do an amazing job!!! Have you ever worked for a racing team?
Congratulations, my friend, for the mechanics videos.
Hey Cameron can you send a link to where you got your case splitter from thanks 👍🏽
Thats alot going on. Starting to love the 2 stroke again.
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
Nicely done Cam, smooth as an eel swimming in olive oil, loved the music score.
Awesome video! I like all the info at the ending too!
Wow, Cameron, you do a great job videoing AND diagnosing. Kudos!
Pretty peaceful videos my dude. Keep'em coming!
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
Another great video with very nice editing and angles!
Thank you for checking out the video!
Man i appreciate so much your patience and effort to do this profissional grade kind of videos!
Well I'm truly thankful for you guys watching the videos and giving your support!
Perfect rebuilt vlog
Great vid cinematography quality. Thanks for time and effor.
Good methods of disassembly combined with good video: well done Cameron!
Thanks for watching!
I cant believe your self taught! That video was very helpfull. Keep up your awesomeness!
Glad you enjoyed the video Jesse! I've had my fair share of learning experiences along the way haha.
Nice vid. At the end of the day how much did it cost to fix it back to running?
awesome video! love watching them, and great camera patience thats amazing, very slick.
Thanks buddy! I do appreciate that.
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....
Mad skills. Well done young man.
why the piston skirt was damaged? worn crancshaft main bearing?
professional equipment and workmanship
Cameron are there anymore videos of this bike? I seem to can only see 2 🤔
I need to learn valves and carb work
Awesome video. But why not wash/wipe the engine a bit before disassembly?
Sick mate another build can’t wait 🤘👌
Did you ever get back together an running?
hi ,,air filter and oil filter its the same as honda 450?
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..
do the 450 and 250r have titanium DLC coated intake valves?
I know the newer ones have Ti valves, not sure on the older bikes.
How much time did it take to rebuild that engine?
Did that ever get a transmission side oil change, damn, some of those parts looked grungy
Great video always learn stuff from them
I appreciate you watching!
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?
Awesome video!👌
Thanks dude!
Sweet vid! Had no idea that valves can get like that.
Thanks for watching!
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
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?
This bike is for parts only. I will be doing a bike build soon however.
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.
Man that was solid stuff.
Great video, as always!
Thanks!
Hi, I'm looking for CRF 450 2010 on injection ? It is good bike ?
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.
Thank you for checking out the video man! Best of luck.
Nice camera work
could you say whitch part is what(just for the main things) on some video for us new guys pls?
Good work 👏
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!
Thanks man! I learned mostly through experience and watching others working on bikes. Been taking notes since I was about 12

Cameron I like your videos man
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.
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!
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!
hi how did u know about fixing dirtbikes or get in to it did some one teach u or ... great vid as all ways
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!
Why does the factory use Phillips head screws? Seems like a bad idea.
Only ever done top end stuff on engines never bottom, after watchig this video i think id tackle a bottom end with confidence
Bottom end build aren't too difficult honestly, just take your time and watch plenty of videos.
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.
OEM Honda gaskets are usually green.
Is there a rebuild video?
Nice disassembly!
Im having trouble kick starting my crf 250r 2009. Takes around 20-30 kickstart. Any helpfull tips what will i do? Thanks mate.
Valves are out of adjustment
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
There was no hour meter on this bike. These motors can last for dual sport though.
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 .
You nailed it, valves were pretty shot
Great video man
Thanks for checking it out!
thanks dude
super skills! wow great vid!
Excelente y hermoso motor ,igual que el vídeo,muy bueno!!!!
Hi, I'm watching your TH-cam 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.
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
Wondefull video Crak!!
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.
Try Ebay, much cheaper than retail
Joz Sports Lets support his shop, your on his channel!
Most of the time I don't have the full sets. Usually something is cracked or damaged.
.....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. : )'
I going to subs u because ure video is inspiring me a lot! Thanks..
The needle bearing on the clutch had no washer on it unless it was stuck to the pressure plate
Did the bike ever get an oil change
great job
How you feeling Cameron ??
So basically keeping air filter clean will prevent valves from being to shim
Great Job.greetings from Poland
Thank You! I appreciate you checking out the video.
Cameron Niemela
I thank you for making such great movies
Never seen a crf450 wt such a nice clutch basket
With all that damage to the Cyl. Wall, I would say someone was doing a poor job of servicing their filter.
I keep having water accumulate in my crankcase breather hose on my 2014 crf450r. Any ideas? Thanks!
Head gasket probably leaking
use bosch go ?
Awesome Video, And Thank God For "Two Strokes" !!! :-)
Yess! I love two strokes.
Any tips for clean bolts? So many get stained
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.
WD40 can fix your stained bolts, and they will stay fresh and not get rusty
I soak all my hardware in degreaser or solvent. That'll strip away all the dirt and grime.
Naanak65 wire brush or wheel, wd40 and some CLR
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
Could we see more full bike breakdowns? Love those vids
Absolutely! I'll have another one coming out next Tuesday:)
Thanks, keep up the good vids
Holy cow I hope I don't have to do this to mine for a while that's way more complicated then the YZ I did
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...
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
This motor came with a whole bike I bought. Yes, all the parts are available on my store currently. www.revivemotoparts.com
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
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.
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.
Its a pity there is no long stroke piston and con rod available for these engines.
Muy buen video..i love the crf 450 Saludos d honduras...
What year?
What' s that for a part at 5:09
That is the shift drum detent and plate.
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!
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 TH-cam.
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
Cameron Can you please Answer A Question i got? If a old 2stroke "cuts" the cylinder and the piston gets stuck cuse oil pump dies, and the bike gets put in a barn, from 1989, whit all fluids as usual still left inside...

Cameron Niemela Okay thank you for the info 😆
So its Worth buying a 1981 honda mtx 125, that got a cut cylinder and have been sitting in a barn since 1989, For 250$ ?
Brilliant Video
Thanks!
The stator of a crf 450 r fits in 450 r ?
450R quad?
She'll buff
Dvniemela 😬
is this ze brothers???
