Yamaha DT 125 R Full engine rebuild timelapse 

Any 10w30 Type SE motorbike motoroil good enough for this.

Both of have the same size, on this DT and on my older TDR125.

@@closethegap9248 ok , thanks so much man.

This Dt was from 1992, but the Dt125x have the same type Engine.

Yes, it was a faulty water pump shaft seal.

Yes, but you can measure the play, and you can find in the manual how much is acceptable.

I sold the bike after this rebuild , but thanks for the advice.

@@closethegap9248 anytime buddy hope you & family ok pal stay strong mylad

@@officialmysteriousrider6327 Thanks bro, you too!

M27 flywheel puller for the dt125r if that's what you mean pal adrian hurtado

thanks for answering and the thread pitch which is left or right

@@hp11000 right & always remember they are different kinds of pullers for the dt125r dt125re mines a 02 model & it requires a 3 way puller if you'res has a cdi box on your oil tank on the front then you'll need a 3 way puller buddy

@@CaptainCharisma2907 110 is good for a 125cc if you're looking for more speed then i suggest Anthea 170cc big cylinder kit with a bigger carburetor but doubt it will last long if you dont give it a new crankshaft or rebuild you could take out your air filter guide & do away with the snorkel but i like not to mess with things like that but that can course cylinder wear & other problems but thats down to you if you want to do that or maybe port the cylinder barrel then that's down to you their is load's of stuff you can do with them but id be happy with 110mph for a 125

@@CaptainCharisma2907 maybe your power valve is half shut then will need adjusting if it has a servo moter or if its a newer model then you'll need your wire earthing off from behind your speedo pal

Hi ! It might be a water pump seal failure. You have to check this first.

Blind hole bearing puller.

@@LHRPerf maybe yea, if you can weld you can easily made a tool for this job !

@@closethegap9248 you mean that i just weld a rod onto that bearing with a slide hammer to knock it out?

@@LHRPerf yes I'd does the same technique

You can do it anything what you want.... the question is You want it or not 🤟😬

@@closethegap9248 i'm sorry I dont understand what you actually telling me since I"m Filipino but base on my understanding you are asking me if I want to do it on my bike, am I right? If that's you are telling me, yes of course I want to upgrade my old Dt125 into the dt125r but the only thing I wanna know if the parts are compatible to each other

Use impact wrench !

@@closethegap9248 not got one on hand i live in a country side and closest place tha has them is 9 miles away and cant afford my own yet as workplace closed cus of covid

@@tifi7160 Use double sided wrench , but you have to use the star side , and you have to punch the wrench with a hammer, this cause an impact effect. Try it, i do this many time, in countrside , near the road :D :/ so ,yes you can do it !! But you must jam the sprocket with a screwdriver to the side case !!

@@closethegap9248 how exactly would i jam it as ive tried many different ways and none seem to work

@@tifi7160 Let a experience mechanic work on it then. 👍🏼

Sorry bro I only have this on YT :( try to slow it down with the speed function on RU-vid

It's a normal revision.

Plus a water pump rebuild.

Oil looked milky

6-8 hours !

@El Cierto I think he wants to know how long does it take a whole rebuilt.

The engine itself is quite resistent, I have had mine for half a year and rolling everyday, more than 5000km done and not a rebuild done
