Honda CRF250R full motor rebuild

What has been going on everyone? So in this video I go through & show you how to do a complete motor rebuild on a 2010 Honda CRF250R. This motor has brand new crank cases & new from the crank up. It was a little bit of a nightmare due to the fact the company we ordered that kit from sent the wrong year crank cases & I didn't notice till after I built the motor the first time. So I had to order the crank cases myself directly from Honda.So everything went smoothly with this video with the rebuild. As always thank you very much for the continued support & if you have any questions about Motorcycles, Atvs, Utvs feel free to leave me a comment are you can email me at [e-mail] also you can find me on Facebook at limitless powersports service & repair.

I am in a very hairy situation involving a time sert going into my engine through the drain bolt hole and this video is by far the best video on youtube for a 2010 crf 250r. thank you for making this video.

[@limitlesspowersportsservic3394]

Hey George. I'm glad my video was able to help you out. A lot of times I will just drill & tap the original case for a bigger oil drink plug if possible. Not sure how a timesert got into you cases. they have a lop on them that you countersync. I've seen that happen helicoils before. I hope you get it all figured out & fixed back up.

[@tristanroberts1645]

Great work you make it look easy👍

[@limitlesspowersportsservic3394]

Hey Tristan. I wish it was that easy when I first started as a Powersports mechanic 25 years ago. lol

[@4wheelsgarage968]

your magician ,subscribed !

[@limitlesspowersportsservic3394]

Thanks a lot. I appreciate that complement.

[@eason9115]

Should i use a small bead of right stuff gasket maker on main crank case gasket? Or install it dry? I’m trying to put center and right cases back together!

[@limitlesspowersportsservic3394]

You can put a really light coat on both sides if you want. I usually install mine dry but to be on the safe side & you don't want to take the chance of having a leak. Put a light coat on both side. But a really think coat. Not a big bead. Use your finger to spread it out nice & thin.

[@eason9115]

Oh good i did thank you! Your video has helped me through this whole process!

[@caseyskaggs7271]

I have a 2011 im fixing to rebuild the bottom end gave up but i noticed you got iy to start right off mine even before any problems took me forever to get it to start any advice on what i might have been doing wrong

[@limitlesspowersportsservic3394]

I would check to make sure your valves are sealing tight. If you have leaking vavles that makes them very hard to starter. Also being that it's a 4 stroke give it 5 r 6 slow priming kicks then makes sure your your on the compression stroke then give it a hard full kick.

[@jowhi9296]

Do you have a full list of tools needed for a 07. Im going to rebuild it. Thanks😊

[@limitlesspowersportsservic3394]

I sure don't but just your basic metric tool set & bearing driver set & the right size flywheel puller, feeler gauge set for valve clearances, proper shim kit. I'm not sure what size flywheel puller you will need. You will have to measure that.

[@ALDA2479]

So I just rebuilt a 2007 crf250r got it back together and now I dont have 4th gear any suggestions are appreciated it goes into 4th but it acts a 2nd neutral idk whats going on here

[@limitlesspowersportsservic3394]

Hey ALDAMONEY. First question is did you take the transmission apart? When I say that I mean did you take it off the gears off the transmission shafts? Aslo did you check the gears for any damage on the dogs & dog houses( the parts on the gear that mesh together)

[@4wheelsgarage968]

im about to rebuild my crf 250r 09 year soon ,will be my first time doing it,hope i have luck ,it have really bad sound from some gears or cranckshaft .

[@limitlesspowersportsservic3394]

It a really good possibility that is the a rod bearing. Have you seen any gold shavings in your oil? that is definitely a sign of rod bearings. You can just get yourself a wrench rabbit kit for the rebuild.

[@4wheelsgarage968]

maybe do a video how to clear carbourator ,would be very helpful ! :)

[@limitlesspowersportsservic3394]

If I get another one in the shop I will try to do that for you. Being that this one is fuel injected not really a lot for go through on these.

[@samcollins3446]

First time builsing a honda in years cant find a video on a 17, i have two orings/d rings and cant figure out were they go, just want to be sure i dont cause my bike to smoke itself.. any help appreciated

[@limitlesspowersportsservic3394]

Hey sorry just saw this comment. I'm not sure which 2 O-rings you are referring to. Did you have to rebuild the bottom end are just the topend?

[@eason9115]

I stripped my oil pan bolt and tapping blow out so I’m breaking down the whole case now does anyone know what special tools i need? I just got to the fly wheel puller part so I just really want to order all special tools i may need at once! And advice would be really appreciated thank you!

[@limitlesspowersportsservic3394]

Hey Eason. Of course the fly wheel puller, clutch hud holder, bearing/race/seal driver for the new bearing your going to have to install. Valve lash gauges so you can set valve clearances while your there. I would also put a new set of rings on your piston since you're at that point too. Off the top of head I think that's it. maybe some snap ring Pliers.

[@eason9115]

ok thank you i did get a full gasket and oil seal kit and new piston and rings and ordered the fly wheel puller so now i just need bearing driver and snap ring pliers and clutch hub holder? Think that will do it?

[@limitlesspowersportsservic3394]

yeah that should. You can use a penny to lock the primary gear in place to loosen & tighten them. Oh a good Newton meter torque wrench

[@eason9115]

@@limitlesspowersportsservic3394 oh good to know thank you for the video and advice!

[@kyriakosmantis2008]

I have a 2014 crf250r that i am about to rebuild because of conrod failure and i would really like to ask you if i can buy the crankcases you took apart 🙂 (sorry about that i could not resist asking i really loved the video thow is the most detailed one I've seen

[@limitlesspowersportsservic3394]

lol I actually messaged the owner of the bike to see if he still had the crank cases which I'm sure he does. I'll let yoy know a price when he does answer me back. I wish is was a little more detailed. I lost some footage putting the transmission back in but thay happens sometimes when you're a 1 man show lol. I appreciate the complement & thanks for checking out my video. Hope it helps you out.

[@kyriakosmantis2008]

Thank you so much i appreciate that

[@limitlesspowersportsservic3394]

My customer said $550 shipped

[@limitlesspowersportsservic3394]

But remember it will need some bearings & seals.

[@HDGENERALLTD]

Do they have to be run in

[@limitlesspowersportsservic3394]

I do like to heat cycle them about 3 r 4 times to make sure all the bearings, piston & rings,cylinder ect... have proper time to break in & that I don't hear any issues with the motor before going out for a hard ride.

[@exupakias]

Just i am asking you, why they put plastic sprocket to oil pump? All companies doing the same!!!

[@limitlesspowersportsservic3394]

I really wish I knew the answer to that. When I worked for the triumph national service center. I saw a ton of the Bonneville with melted oil pump gear because when they sit there & idle they get to hot & would melt then. I'm guessing it has something to do with heat transfer are noise.

shhhhh don't tell everybody lol

[@iRiDE667]

If you're gonna start a video then you should finish a video. Don't half ass it. Never showed the full internals.

[@limitlesspowersportsservic3394]

Hey Tyler. I appreciate your feed back & checking out the video & I totally get where you are coming from. But some times things just don't turn out that way. When your trying to do it all yourself there are times when you're working you don't realize that you are leaned over infront of the camera are that you mic went dead, footage get corrupted. Are in the case you're talking about nothing was in focus & I kept leaning in to the camera shot. So it was unusable footage. That's where editing comes into play. Sorry I can't afford a professional camera crew are editors to help me out. I would absolutely love to have that. But also take into consideration I'm also doing a paying job for a customer & the perfect video is the last thing on my mind. My main goal it to make sure the job is done right the first time. I would love to be able to go back & re record a lot of stuff. I try to do that on all my personal projects but unfortunately in this industry time is money. I hope you can understand where I'm coming from.
