Honda CRF 250 RX - repair of the damaged cylinder head.

[@loopeyshooter503]

Thanks for another fantastic video Paul. These really are hypnotizing to watch. The journals where the bearings run on my uni cam crf450r have some galling where the bearings run but doesn't seem to effect operation. Bike has 330 hours.

[@CactusforceX]

Impressive stuff, this kind of damage fills me with fear - especially with rare bikes with no new heads around. Glad to see that a decent repair can be made if you have access to a machine shop.

[@hororr4409]

Bro, as always, on Top!))) I'm glad that the content is being created! for a long time there was no work with metal that can give emotions!

[@alexthebear]

Paul, you are great! Enjoy watching your videos.

[@TallerdePueblo]

You are amazing, a true artist.

[@MrPetRooster]

Do you do customer work? I have a head from a 2007 RMZ450 that needs both journals repaired.

[@professionaloverthinker-x]

Incredible work.

Like a boss..Excellent work, again!

[@pasqualesgro]

Ciao Paul, sei un artista della meccanica. Grazie a te ho risolto un problema sulla mia moto. Volevo chiederti, perché non usi il bronzo anziché alluminio? Per una questione di differenza nella dilatazione? Se l'acciaio gira su bronzine non ha mai fine. Grazie

[@farshidzr]

Very very good job 👍

[@Ivanesquevan]

Amazing work Paul!!!.

[@panagiotibe]

[@Ютубовец]

Просто космос! А от чего это произошло? Масляное голодание или перегрев?

Yep. Bunch of hackery in a 14,000 rpm engine.

Moto muito linda 😍

[@avsmotosolucoes]

Amazing!!!

[@isaiasdiasfernandes]

Perfect!!!

[@raphiwitkasemsnkphaisan9829]

ดียังไงคับ

[@OneEye.]

I would have broke out the TIG and filled the cam journal and then resized to cam bearing spec and would have done a fill on the cap also to align bore to size.

[@chasebelcher7932]

Absolutely 💯 would have done the same

[@KhaiNguyen-nn5ue]

Quá đẹp 👍

[@troonsclasic716]

[@xyesman5519]

Great repair but poor head bearing design. Would better trust in ball bearings

[@mastergambiarra]

Acho que se ele tivesse preenchido com solda tig ficaria muito melhor e mais fácil 👍 🆗️

А тяп ляп.

[@dc6233]

Such a dumb ass OEM design!! There's barely any surface area for the camshaft journal to ride on. Honda has been plagued by the "backwards oil filter" for decades, all the way back to the Honda ATC350X. It fits both ways, if you don't pay attention, the head starves of oil.

[@OtisFlint]

Surface area is drag. These are race engines from the factory, they are not intended to last. There are always trail bikes for guys who don't care about performance.

[@kawasakirule3707]

Stay with 2 Stroke. U won't GO BROKE. LMFAO

[@loopeyshooter503]

My list of blown up two strokes: ts250x, rgv250, rz350, rz500, ktm 300. My list of four strokes: husqvarna te450. My pocket says otherwise.

[@kawasakirule3707]

@@loopeyshooter503 I never had any problems with mine. So maybe it's just U. LoL

[@CactusforceX]

@@loopeyshooter503 it helps if you put oil in them matey! xD

[@arzyfauzy9670]

Both 4 st and 2 st had engine lifespan... but 2 st had less moving parts..

[@kawasakirule3707]

@arzyfauzy9670 grew up in the 60's riding 2 strokes. So yes we did work on them. Unless it had to be bored. Or the crank rod replaced. Now crank rods I do myself. Boring Not. LoL
