Bout time to put this engine together?
Can't wait!
Cameron Niemela you are awesome
Cameron Niemela The 250 will be better then it left the factory.
Dont forget to replace your clutch actuator arm bearings in the left side crankcase. I dont think the wrench rabbit kit includes them. At least they didnt when i bought mine for my 98 250. Cant wait to see the build complete.
Yeah it’s time to get my head re built on my 02 crf 450.
The dirt bike chrisfix!
Oke when i saw this reaction i knew it was the best vid😂
Exactly!
I really like the scotch brite wheel is awesome. Not overly aggressive. Wrap it up with some Aurosol on either regular bench buffer or dremel buffer pad and it will end up amazing.
Can you make a all in one video on how to rebuild a whole bike and tearing it down
Mate I love your content it’s always exciting to watch someone who’s patient with there work im keen to see this cr250 being put back together
cant wait to see this finished!
Never use a gas Torch in aluminium cases, the better way to pull out screw with loctite or ball bearing is to heat the parts in a hoven, 150° Celsius are quite enough and the thermal stress is very Little.
Great video as always! Cant wait to rebuild my buddy's klx and ttr, gunna have to watch your ttr videos for some help!! That's what I love about this channel, you sir have taken #1 youtuber in my opinion 100%
How did you get the engine to look so smooth instead of all scratched looking?
bro, after assemblying the engine parts again will it effect the engine performance ? Will it have the power and torque that was there when it was manufactured first at the company factory ? And what is name of the brush u used ?
Great video, Thanks! Not sure if this has been mentioned already but when you run into what appears to be Phillips screws on a Japanese product don't use a Phillips screwdriver because they are not Phillips. They are in fact JIS screws (Japanese Industrial Standard) They have a different form to them than Phillips. While Phillips are designed to cam out JIS is not, but use a Phillips driver on a JIS screw and they they will bugger up the screw. Best way to ID a JIS screw is to look for a dot on the screw head. Although JIS screwdrivers are hard to find the impact drivers usually save the day. Hope this helps those who wonder why Japanese screws always get trashed when removing them with a known good Phillips driver.
A cheapo trick to get by is to buy a harbor freight #2 phillips and grind the tip back a bit. It allows for more contact on the screw. Then buy some JIS drivers.
shut up stupid.
Thanks for sharing. I did not know this
freddie cancel dude, chill out
Aren’t JIS more square instead of a diamond in the middle of a plus? That is the best way I could think to describe it without a picture
Dude... U really had the patience to polish all that... Oh my god!
I thought u were simply Going to clean and sandblast.
Amazing
Dude, you are so inspiring to me. This is exactly the kind of stuff i also wanna do. Ps. I want your workshop xd
simply amazing. takes a lot of patience and dedication for making those parts that clean
This is such a great video, so helpful in so many ways, thank you Cameron!
Safety tip - those cases have razor sharp edges. I clipped an artery on my finger once while cleaning one, and now use mechanics gloves whenever working around them, especially with a high speed machine.
Are you going to clean\ repair thr exhaust system?? If you are going to do it, can make the video? I need help with this
What i usually do is use a steel wire wheel on an angle grinder to remove all paint or rust, and then i spray the insides of the exhaust with oven cleaner a couple of times and then preassure wash it, then repaint it.
Bike frame paint removed
cameron never stop doing what you are doing, youre a huge inspiration to me and your vids are both entertaining and extremely teaching. wish i had such a good garage as you.
soderholm hi
Hahaha u should do my bike next, jk man but awesome vid as always!
Even though I work on smaller engines, such as Zenoah's I've got a spare toaster oven that I can heat aluminum parts up in evenly to about 130-150F and then just freeze the bearing and the leiden frost effect will let them drop right in and will burn off quickly.
I wish I had your job get work on dirt bikes and ride dirt bikes all day everyday
It's nice when a job is completed to perfection!
When I did the case on my YZ 250 I popped the cases in the oven at 200 for about 2 hours and everything fell right out . I did the same thing when I installed the new bearing , but I put all the bearings in the freezer the day before and they dropped right in with no issues
I will watch the rest of this tomorrow, the movie "The God Father" has just started on tv
For difficult to reach areas buy a length of bowden cable, cut into 3 inch pieces and tape together. 7 is a good number to retain flexibility while allowing pressure to be applied. I also always finish off with 400 grit wet and dry whenever using steel wire on ali otherwise the finish is just a series of scratches.
Yo Cameron, I love your videos. Watched a bunch of them, all are nicely put together and informative. Right now I'm fully rebuilding a CR250 '00 engine, which I also going to be using your tips to get the crankcase halves looking this good. Thnx for sharing.
The method i usually use to get a “perfectly” flat surface on gasket surfaces is to buy a sheet of fine grit usually 400-600. Wet it with wd-40 as opposed to soapy water and secure the sandpaper to the flattest surface you can find(the real reason i bought the wife a granite countertop)
Nice job cam, love the patience and detail. I love doing all this myself and your vids help me skip the trial and error drama. I'll be picking some stuff up at your store.
Salut Cameron ! Excellente vidéo ! Très bon job !!! Polie toute l admission, ce sera mieux ! Très bonne journée ! 👏👍👌😉😁💨💨💨💨😎
Neat trick for those blind hole bearings. Put heavy grease inside them, stuff paper in axle hole and hammer that paper, remove it, put more grease and repeat . You will create quite surprising amount of hydraulic pressure and you can remove bearing without blind hole puller tool. I've used this multiple times and I know it sounds incredible to many, but this really works when done properly.
It was the way (don't know if they still do) mechanics used to remove pilot bearings from flywheels/cranks.
Get a solid bar that fits snugly in the hole, fill the hole with grease and tap the shaft in. Bearing is forced out.
I've seen people use bread to do the same haha
For all those who don’t have a blind bearing puller, find a flat end punch close to the inner diameter of the bearing. Take single ply toilet paper and wet it keep packing and hammering in. Bearing pops right out
It might sound weird, but bread works for that, too.
Those impact driver screwdrivers are absolutely invaluable!
For real, best money I’ve ever spent
Facts i can't belive i didn't know these existed before
They are not Phillips screws they are JIS. I assume that, if you are working on Japanese bikes, you have the correct screw divers. Using the wrong ones will trash the heads.
Whose here before 100 views? :)
Devin Niemela me
Damn I slept in and missed it
I’m here at 141
One thing for anyone trying to tear an engine, heat up every bolt/nut to be safe, especially if you’re a rookie! Best tip out there. And drivers.. lots of drivers… I remember my first clutch nut, I had to grind it off.. and my second one I just gave up it on and left it. Nowadays first heat, and an impact driver.. works like a charm. PS I pre-heat EVERY bolt and nut even case bolts before. Only stuff like plastics I just wd40, those can be dremelled
I ordered my first polishing wheel and let me say this is the BEST thing I have ever used to polish my aluminum parts . It takes years of tarnish and corrosion off in seconds leaving a like new luster . I also purchased the buffing wheel for a drill to reach hard parts and it works fantastic ! I highly recommend the products and very quick order processing I received on my purchase .
Thanks Marc! Happy to hear they're working well for you. Happy polishing!
I just put the whole case in the oven for 10 - 15 minutes, bearings mostly fall out
I concur
Cameron is probably the tidiest , cleanest , most professional mechanic I know of. We could all learn from Cameron and raise our standards !.
Great job but you’re not done yet. They make very tiny buffers for your drill to fit it small spaces. You will use the first stage which is a rough compound/black bar. You will use the 2nd compound/maroon bar and then the polish which is a white bar. Make sure to switch buffing tips and only use them for the type of compound or polish your using. Same with the rags. Clean only with the rags for that compound or chemical your using
Do a video on how to convince your parents to let you ride dirtbikes
Quality content.
hey cameron gracias por ser un maestro de la mecanica y dejarnos ese legado un saludo desde colombia
Good video, but do you think that polished aluminium won't corrode in a short time? IMHO Honda bikes comes with some coating from factory to prevent it. Stock Honda engines that I've seen are not shining, they are just grey.
Dmitriy Krupin certainly needs to be reanodized or it will turn into garbage within weeks.
Your work is awesome. This cr250 will shit all over hondas factory build haha I'm keen to see what you do with the topend, Oversizing? Porting? Port matching? Reed valves an cage? Carb? Endless possibilities mate keep it up love your vids, take care Mark.
Hi in no mechanic…. I’ve just split the case on my 01 cr250 … my cases are at the stage you are now … why ares yours so clean ? … I’m putting in a vertex rebuild kit …. Can I now jet wash the cases with water to get the grease and oil off them … as I’m sending them away for aqua cleaning … ? I don’t have a parts washer 😢 … what do you suggest ?
isnt there a bearing for the clutch actuation rod in the case?
Great attention to detail Cameron, I have seen similar results just with vapour blasting with wet soda in a cleaning cabinet like you already have. Maybe worth investing in this kit???? A bearing press is useful too. 👍🏻
Dude do NOT use a sanding pad to lap your cases. It's going to be uneven. Get a nice thick piece of glass and cover it with some fine Emery cloth. Lap your gasket surface by sliding it over th Emery cloth in a figure 8 motion.
Hey dude!!! I dont comment very often but I had to let you know how much i love your videos and your work!!! I really cant wait to see what your plans are for this bike! Those cases are getting me jealous 😂 I wish i could do what you do 😊 Youre my model when it comes time to work on my bike. Thanks alot for the vids you are my favourite youtuber hands down 😉 Wish i had the money to get some Pryme products and help you out with the build ! PS Love the more often vid release but dont forget to take your time 😊 Peace ! ✌
Thanks man!
How do you keep this beautiful aluminum from instantly tarnishing again? Is there a coating that will keep it nice for a while?
The Whole idea is to heat up the cast Not the Bolt ! You want the case to expand a little Not the bolt! When reinstalling bearings you want to chill the steal & heat the aluminum / magnesium case or part Not Reversed! Just a tip! Dont fight yourself!
What brand buffing wheel is that? Im looking for a large stand buffer. That one seems very nice..great work!
Labor intensive. A vapor blaster would make your work much easier and the finish is unbelievable. But I'm sure you already know this.
when I bought my honda cb450 in 1966 one of the things I also bought was a impact screw remover. Well worth having.
Use extreme caution using that bearing puller. I suffered a nasty wound between my thumb and index finger. Pinched the joint and it bleed for a week.
Popping the bearings out would've been easier with a hydraulic press but you gotta work with what you got... great vids I enjoy watching them... I learn a lot despite being a mechanic by trade
Great to see the cr250 build back on track...keep up the good work fella
Nevr dull or brake cleaner will take all the discoloration off after you brush or scotch brite. After that finish with a clean buffing wheel with no paste :-)
If your trying to resurface gasket surfaces to have a perfect flat sealing surface wrap or even lightly glue sheets of sandpaper to a piece of plate glass and move the part over the surface rather than moving the sanding surface over the part plate glass is a true flat surface you can actually even resurface car engine heads this way but dirt bike engine surfaces work very well using this method many sanding blocks are not very flat and you can't sand the whole surface at the same time which in some cases lead to an uneven surface.
Can you do manually with rubbing paste and cloth ?? I want to polish mu crankcase without taking them out from motorcycle.
Want a better finish? get a harbor freight sandblasting cabinet but use baking soda as the media and it will clean and polish at the same time. You will be amazed at how fast and smooth the alum will be when finished. check into it ...some youtube video on this.
I put cases in oven at 350 degrees for 20 mins and you’ll hear the bearings fall out , get new bearings out the freezer and they go in with ease ,
Started to really get into building bikes for the last year or 2 you’ve basically been my guide though it all lol great videos man 🤟🏻
hello awesome video, do you protect your motors with some sort of coating? or just wash it every ride?
Just put the whole case in the oven at 450 degrees for 2o minutes and the bearings will practically fall out
You Owe it to Yourself to buy a Foredom Flexible shaft machine.
Its like an asmr Video for Maschine freaks 😂😂🤙hold on buddy 🤙
Very nice video thanks فيديو جميل جداً شكرا
what about a little tiny mini orbital sander with a scotchbrite attachment. Would that work? (if it existed) lol
Aren't the cases powder coated to grey? Does it start to rust if you don't powder coat or paint it after doing this?
I used to do all the polishing when I had my dirtbike. But I got tired of it and just started flat black painting it
One thing you should mention is that the screws retaining the bearings are JIS head screws and are super easily rounded out if not using the appropriate bit. Otherwise, keep up the good work, like your videos!
The JIS screw is signified by a single dot which can be seen in the video
Ouch!!! Brutal. Put in the oven at 150 C and they fall out. Even the blind ones.
Nice video...now that looks better than new..
Of course another great video! Impact screwdriver is worth its weight in gold! I use mine ALL the time!
why no Turkish subtitles
Is Türkiye an insignificant little country in your eyes?
did you coat it with any product after polishing? I wanna do the same thing but I dont want it to rust after a while
Impact Screwdriver, or as they should call it, a frigging life saver
Cameron there's a lot of pitting inside on where the flywheel sits would this be issue?
Did he just tighten the hell out of the outside nut to use the "double nut technique", I thought you used a wrench on the inner nut and let it tighten against the outer nut.
Cameron can I ask why you never polished the intake and around the crank ? surely that would make for better power and delivery? i only ask as I was toying with idea and wouldn't mind some tips. or if there are any pro's or cons in doing this?
There's a lot of science and design behind porting. Not my specialty
I used to get carb cleaner in 5 gallon cans,cleaned everything up,just dip it and done
Another solid vid from The Man.
save your self a days work and pay for vapour blasting. better result too!
I love using the double nut technique on my girlfriend, not my bike
Did you use the fine cleaning or just the cleaning scotch brite pads?
I am about to split my engine this weekend. But I think I am going to paint the cases and polish only the side covers.
I successfully pulled of the “double nut technique” once in college.
The Phillips head screws strip out easily because they are not Phillips screws, they are JIS. Use the right screwdriver, they wont strip.
I recommend Vessel impacta, a regular screwdriver that works as a impact driver also
Man that case looks like a piece of jewelry. I was wondering how long it takes for the oxidation to set back in?
Oxidation comes back almost instantaneously. You can use clear lacquer or even collinite insulator wax immediately after buffing to hold it off.
Gotta get me one of those hammer screw drivers.
You are a great guy Cameron I like how you Work I would like you to give me mechanical classes succes 👍👍
If you're working on a Japanese bike, or anything else from Japan, then the Phillips screws that strip out AREN'T Phillips screws. They are in fact JIS (Japanese Industrial Standard) screws, a Japanese version of the Philips. If you go on Amazon you can get the proper screwdrivers to help avoid cam out.
I'm completely restoring my '03 KTM450EXC soon, and will be using your engine cleaning techniques, but I'll be going one step further. So that I don't have to do all that polishing a 2nd, or even 3rd time, I'll be cleaning all my polished areas with acetone, then coating it all with a High Temp "Clear" ceramic coat, baked twice to cure, so my bike comes back to looking brand new after every wash!
You're right about the impact screwdrivers being handy but if you don't grind that scary mushroom head off it you'll be picking pieces out of your neck like my friend did. 1/4 inch closer to his jugular and he would have bled out.
Big fan, but i do my bike parts wit sandblaster.
Very good video man helps me a lot on my bike builds!
Your awesome,so many people don't share this kind of stuff because they feel you should have to pay $1000 plus for something like this.when you can do it yourself and do better job then they would do 🤘😜awesome video bud looks brand new
My hips are uncontrollably humping like a dog as I watch this video. Nicely done! ⭐️⭐️⭐️⭐️⭐️🤛✊☝️
Holy wire wheel! What is your time worth these days? On swingarms, mirror polished looks good. On engine parts I'd want a rougher surface to shed heat.
Good video
