New Top End? Here's How I Break it in

Decent Garage merch: decentgarage.com/
I did a lot of research and reading on how I should break in my bike after I rebuilt the top end. Based on my research I followed Motoman's procedure with some tweaks to that.

I know this process can be somewhat controversial. With that, what are your thoughts? What would you do different or what would you do on top of what I showed here?

[@10mm]

You did it exactly the way I would! Great vid as always

[@kuladeeluxe]

your approach of loading the motor makes sense to me. Should run a very long time.

[@morganeast3403]

Yeah what a view I lived on flagstaff 25 yrs and rode then a xr600r and a yamaha 1976 ty250 trials they fit all my bills.

[@buddywilson104]

Sounds like a proper break-in to me. Personally I think the key is the hot-cold cycles. Running it for 15-20 minutes and letting it cool down completely; repeating this a few times seems to work well. Thanks for the video.

[@decentgarage]

Glad you enjoyed. This was almost two years ago and the bike run like a beast still.

[@OldDirtBikes]

Love it . Good job on the top end . In my experience it’s the first hour running the most worrying time ,if something was wrong. But that’s sounds sweet

[@decentgarage]

Thanks! Yeah i did a video on how i broke it in as well

[@iluvducttape1]

Looks like it runs good! Got me itching to go ride

[@decentgarage]

I'm so ready to ride too haha

[@morganeast3403]

But I now live in Kingman have a 2020 yz450x and a 96 xr400r w a big bore kit I'm fixing to do the top end again

[@elflaco8754]

i have the same bike and won't start what part of Utah is that?

[@simonmears1726]

Im going 440 on a 2003 model with new valves and seals my approach to run in is start bike warm up on ride nothing over 60 kmh 20 minutes then back let motor cool right down then repeat procedure slowly building Kay's and speed get a nice ring seal and oil change should be good to go

[@dukesilver2019]

That looks like the Wasatch front in Utah. Miss it.

[@decentgarage]

You go it!

[@jaymervin6888]

Orem here in da hause also ! Doing my top end on my 01 now ! I like that break in procedure !

[@decentgarage]

@@jaymervin6888 let me know how yours goes! Your close by to me

[@richardlyons5861]

great job on ur rebuild and break in procedure.that the way I've done it.let her eat now guy👍🤙🤙

[@decentgarage]

Bikes been running amazing ever since!

[@morganeast3403]

Good info.

[@LarryLoopout56]

Hey mate, what oil did you happen to use for the break in process? Mineral then onto full syntho ?

[@decentgarage]

I use 15-40 motor oil for all of my dirt bikes. I k ow oil selection can be a hot topic so i didn't even bring it up

[@paxtonspeed]

I would have swore the auto decompression failed and caused it to lose compression. Do a stage 2 Hot cam, and cut the top of the air box open. Then jet the carb.

[@decentgarage]

Auto decomp was functioning fine...

[@morganeast3403]

I was tokd to run up ndown like you said get hot 2 x doing that then ride as. U would.

[@benkanobe7500]

As much as this has been a part of engine building/rebuilding for at least a Century, I 100% assure you that HONDA does not do any kind of "Break In" at the factory. In fact, the brand-new bikes are all put on dynos and run quickly through a series of tests to ensure all shifting, oil pressure, speed, power, temperature, and charging, are achieved within specifications. Then the oil is drained and it moves on to shipping/boxing. So if HONDA doesn't do it, why do we all think we need to?

[@chiliboom6140]

I’m gonna assume, only my thought on this, if it needed to be redone when he had it, perhaps it may have gone longer before needing that of Honda did do a break in. But I have no idea, that’s just my assumption.

[@benkanobe7500]

@@chiliboom6140 I was a Design Engineer for HONDA and lived in Japan. Not One HONDA M/C engine ever was treated differently than explained above.

[@chiliboom6140]

@@benkanobe7500 Cool! Thanks for the info. 😁

[@RideWithTheWolf]

Guess I have to do mine. Seized up after a race. I unseized it, but not starting, now. It was low on oil, is it possible its ok?

[@decentgarage]

Probably needs a new cylinder along with the piston and stuff

[@RideWithTheWolf]

@@decentgarage so it gets hot in there and the rings or the cylinder fail. But maybe the valves are ok.

[@decentgarage]

@@RideWithTheWolf only way to know for sure is to tear it apart.

hola compañero, me gusta que hagas videos de la honda xr pues yo tambien tengo una, te invito a pasarte por mi "canal", pues subí hace unos dias un mini tutorial de como cambiar los rodamientos de la rueda trasera, próximamente voy a cambiar los de la rueda delantera y prometo que lo hare mejor, mas detallado. aunque estoy empezando ahora a colgar videos asi que no esperes un gran canal.lo que si queria preguntarte es por que le cambiaste piston,aros,etc?soltaba aceite por el escape? mucho olor a aceite o humo? te lo pregunto pues hace nos dias que la mia ha empezado a manchar un poco de aceite el guardabarros trasero y huele un poco,quizas me anime a cambiarlo en breve,ademas noto que consume mas aceite de lo "normal" por cierto, buen trabajo de rodaje del motor, por aqui se llama asi precioso lugar donde vives, pero veo que hace mucho frio aun, hoy hemos llegado a 27 grados centígrados aquí

[@wyattstevenson656]

You know what my favorite thing about my 2019 KTM is? The electric start 😉

[@decentgarage]

You're going to get my videos flagged for hate speech with comments like that.

[@andrewr4220]

Electric start = Cane

[@decentgarage]

@@andrewr4220 perfect analogy!

[@chiliboom6140]

They make electric start kits for these. Not even gonna comment regarding the KTM. We all love to ride and would help each other on the trail. Ride on.

[@simonmears1726]

Ride the red dragon like u stole it wide open every where is a honda LoL 😂

[@decentgarage]

Have only ridden it about 20 miles since this video. Thinking about selling it to fund other projects...
