- This video is a complete step by step process of the easiest way to tear down a 2004 CR250 two stroke dirt bike engine. This is a full disassembly of the engine and I do things a little differently with this one by starting with the BOTTOM END first before tackling the top end. After doing it, I believe it is the BEST and EASIEST way to get a dirt bike motor torn apart. Check out the video to find out for yourself! Leave a comment below about what you think about starting with the bottom end first!

Absolutely loved watching that!! Will definitely start from the bottom end next time!
Yewww!! I will never start from the top again, tearing the bottom first is the way to go, thanks Bino 🙌🏼
Makes sense! I’ve always taken the top down approach but methinks it’s time for a change. Lol. Good stuff Greg! 💪🏽
Hells yeahh! I'm hooked now, I will always do it this way going forward
awesome work! love your videos.greets from austria
Thanks man! i really appreciate that!
Another A++ Video man!
Thanks Linden! Stoked you are liking them man 🙌🏼
Hello my friend !! I always watch your videos and I love them. I am from Chile and I would like to ask you a question my friend. A crankshaft with connecting rod from another year, such as a CR 250 year 97 or 95, works well for my Honda CR 250 year 91. help please!! regards
Top quality teardown man glad to see this went a bit easier than the ball breaker Rm 😄
Thanks man! That's hilarious, ball breaker RM is accurate!
I noticed you measured the clutch steel on a wooden table and gauge went under it. I'm sure it's still within speck. The only thing you have to be conscious of is that the wooden table might have a low spot on the surface that might cause a gauge to slip under the steel. Just something to consider?
im looking for it i have i broken one how much you charge i also need my motor rebuild
A good way ive found to take the clutch hub off is put a steel plate back on and hold it with pliers, has worked really well for me so far. Dont need a special tool either. Understand its not the best way if you reuse your plates but it works well.
Not a bad idea, especially if you don't have the special tools to do it!
@@GregHitchko Yep, just brought a 09 kxf250 and a 2000 kx250 engine to put in it. Wanting to do chevy trucks graphics like your kx, that bike looks so mean!
@@Jack-vh2kn that is going to be sooo sick! I can't wait to see it. I'd love to do an AL conversion sometime. @Melodesignco will make it happen on the graphics side of things if you don't have a company you're working with yet!
@@GregHitchko Yeah i cant wait to start, got a guy that will do fab, i can do everything else. This will be my first custom sticker kit so i dont have a place to have them made. Im in australia so it makes it a bit more difficult.
@@Jack-vh2kn Hell yeah, I do hear that it's super tough to get parts to countries outside of the US!
Use a hammer impact wrench on those Phillips bearing set screws for easy safe removal and install
Good idea on that! I need to use it more just to be safe!
How do you get them out of that dosnt work
Thanks for the video. My 02CR250R has MTL oil leaking into the Magneto side of the engine what would cause this? Since discovering the slow leak I've been premixing a bit richer thinking it may cause a lean condition? Can oil also be getting into the crank area burning through the engine?
Hey Scott! Seems to me like you either have a blown crank seal on that side, causing air to get it, making it run lean. Or you could have a leaking clutch actuator arm seal. The clutch actuator is much easier to replace because you don't need to split the cases for it. Where does the MTL wetness seem to be stemming from, can you trace it to the source?
@@GregHitchko Bike isn't actually running lean plug looks good I just assumed if there's oil leaking into the flywheel side of the engine it's probably seeping in air while running. From what I can see oil is coming in from behind the flywheel.
@@scottmeyers4178 dang that sounds like the crank seal is shot on that side of the engine. I'd recommend tearing it down and throwing a new seal in there if that is the case before any real damage occurs.
Any big differences with a 1996 CR250? I need to get to center case gasket but not sure if I have to pull everything off.
The 96 has a different power valve set up but shouldn't make pulling the engine apart any different. You're referring to the gasket between the cases, correct?
If you pause it at 19:49 the exhaust bridge right below the top of the bridge looks like it is cracked to me... I've seen it many times with these engines
I am seeing that now in the video. I will have to take a closer look at it when I go out into the garage. Thanks for pointing that out my man!
No problem man 🤘
Would this be similar to doing a 1995 model? I recently bought back a bike I owned 11 years ago and the trans is not feeling the greatest 😕
Heck yeah that is awesome dude! For sure, You can follow this same process to disassemble the engine on pretty much any two stroke. Good luck on the tear down and let me know if you have any questions.
nice
Thanks mate!
Ok, I’ve got a question for you Greg. Can you remove the right side case without removing the clutch side or ignition side case?? I’ve got a motor I’m doing and found a stripped oil drain bolt. My plan is to remove the right side case and send it to Eric Gorr to get the oil drain hole welded and re-tapped. I’d love to do it with out pulling all the stuff out of the left side case. I’ve always split these by lifting off the ignition side first and have never tried lifting the right side case first. Thank you Greg. You are amazing!!
Thanks for asking Cody! Sounds like you've got a project on your hands. I know it is a pain but I would feel better just disassembling the entire engine and rebuilding it from the split cases. Reason being, I feel like there would be weird torque put on the side of the engine that was kept together, potentially throwing things off when you go to put it back together. That is my opinion and what I would do, but I'm sure there have been people tat have done it!
Thank you Greg!! This one has been a nightmare. When I went to bolt on the new Eric Gorr 265cc cylinder, I noticed one of the case bosses for the front most left side cylinder stud was cracked. So I took it all apart, pulled the motor, sent that left case to Eric, put it all back together with new bearings, got the Lectron on and the exhaust, filled it with coolant and right before I went to put trans oil in it I thought I’d better make sure the oil drain bolt had a fresh crush washer. Then I found that problem. Oh well, looks like she’s coming out again. Why don’t people use torque wrenches!!!???? Have a great Sunday Greg!!!!
@@Yqsw750001 Ughhhh i want to dislike this comment for you lol. That's rough dude, but hey think about it this way, at least you will be an expert now at taking apart the motor and rebuilding it! It should come apart and go back together in no time.
Is their any major difference between this 04 engine and the 03 cr engine
Nice video. I just wish there was no background music when you are explaining things as its a distraction. My .02
Did he say radiator fluid?
Also leaving cylinder on is unnecessary, just use and old pair of underwear jammed in the gears or clutch and get you a bigger 1/2” impact, easy pleasiey
Haha just gotta make sure there are no skid stains in them first right ;) Good stuff my dude, thank you.
I need a cylinder and crank for 1988 CR250?
Unfortunately i don't have either of those my dude...
do you have any contact I have a cr250 year 91 and I need to buy some parts there in the USA. I found parts on ebay but not sure if it's reliable do you have any tact
Unfortunately I do not my dude :(
@@GregHitchko I'm a mechanic can I get a job easily in California
I need a crank
You still got that crank
I do still have the crank! Email me at hitchmotoko@gmail.com or DM me on instagram @greghitchko
What’s the easiest 250 engine to tear down
I would say this CR250 because the PV assembly is the easiest, least amount of parts compared to the other models!
You can shove paper towels or wash rags in between the gears instead of pennies because metal on metal isn’t the best for it.
I’ve tried that before with not the best luck! Guess I should have shoved more in there lol
😢
Another worthless video. Does anyone actually know how to stack the gearset?
Dang you're giving me way too much credit 😂😂. I was wondering if anyone would catch it. Thank you for your time Paul!
Great video I've got to do it my first time doing it it's been a year I'm sure you don't have the crank still
Right on Marty! I definitely prefer this method for sure. Unfortunately the crank is gone. But as long as you send it to Millennium Technologies for example to get rebuilt, you will be golden my man. let me know if you have any questions on the tear down. Thanks!
@@GregHitchko I do have a question my cr250 is in a outlaw go kart it's stroked should I keep it stroked or should I go back to a stock crank ? It don't seem to have any bottom end
@@martywolf1819 these CR’s struggle in the bottom end department unfortunately…I’d look for a Pro Circuit Platinum 2 pipe or an FMF gnarly. They really move the power down low.
@@GregHitchko oh great another $500 pipe ha ha I have a esr 9b pipe and it say it's a mid to hi range pipe it came with the kart what about the stole rod does it really help ?
@@GregHitchko I looked into that pipe they are cheap but won't work they are a diff shape for the go karts but I need to come up with something for more bottom end too bad I can't post a picture
