for people who want to save time. dont take the head off. unless the gasket is damaged or you are having compression problems there is no need, just slide the barrel out from the top and give it and the powervalve butterfly a good clean with carb cleaner/brake cleaner. great video by the way.

the simplicity of a two stroke is a refreshing thing to work on as a mechanic

At 7:29 you are missing a washer/bushing where your power valve actuator arm attaches. Also put a rag below to block the pin from falling into the right side cover. Nice job on the production of the video.

So much satisfaction watching this

my last rebuild on my 2001 honda cr125 was a pro x piston too, lol. nostalgia. i am currently a year or two into a very slow going project of completely rebuilding my bike. only initiated due to 3rd gear popping in and out. hopefully i will be finished in another month or two. i cannot wait to ride again. i need to feel alive. its been too long. work, sleep, work, sleep. i cannot fucking take modern life much longer without a bit of escape. 2 stroke heaven provides said escape. so damn good.

this is the best instructional video iv seen thus far

I'm a very rough critic i would say and your video is flawless. Everything is clearly told what to do , the music and the camera angles just makes me happy watching this video! Thank you very much, I have a cr125 2004 frame, 2001 engine. Your video will help me a lot since my engine blew up and am going to rebuild it soon.

I was waiting for the way he installed the piston with the rings on into the cylinder. .he skipped the most critical part ...

Thanks for helping everyone who is a do it your selfer. I bet this video has saved a lot of people a lot of money.

Why I love 2 strokes! So easy to work on!!

probably the best rebuild video ive seen on youtube, very nice! faved

I don't know why, but this video was extremely satisfying and mesmerizing to watch, and very educational! Thank you!! I'm going to go buy a CR125 for my daughter with a blown head gasket, and rebuild it! Better to do a teardown anyways buying a used bike, you never know how the previous owner treated the poor thing!

Thanks Devan! im glad you liked the video. I hope to start to make new videos soon. If i was you i would change the top end on a used bike that i dint know anything about. Its the best to be on the safe side.

This video really helped me when doing a top end rebuild on my cr 125... many thanks and keep up with the great vids!

Great video, i did a full rebuild on my 97 CR 125 a couple months back, Good job at not ruining those gaskets.

this was the best top end rebuild movie i have ever seen ! very good!!

One of my favorite rebuild vids.

great video just bought 87 cr125 to restore came across your video had to watch.

really good video man, im doing a top end soon and this video has helped me understand how to do it way more, sick bike btw man!

It's my first time working on a cr125 and I was looking for a video to get some advice. I never thought that I would find such a well made and invormative one! Thank you very much! Now lets go get some oil on my hands ;-)

Thank you great vid. Off to install my new piston

I can't put my finger on why but this is deeply satisfying to watch.

thanks for posting this video. i have only rebuilt a 400ex once. trying to refresh my memory. getting ready to rebuild my rm250.

Awsome! TY for posting this video! well done and the bike looks great.

wow this is by far the best instructional video i have ever seen period. I feel confident now that i have watched this video that i would have a descent idea of how to do this rebuild. Great video keep it up

Man, great job. Loved the song that went with the video

BEST VIDEO ON KZread! i luve u so much ure the most epic dude of all time thank you! :D

Great vid

excellent video

It's good to dissasemble the power valves because when you're starting new with a fresh rebuild, there good to clean because over time they build up alot of carbon and don't want to work properly which can have a huge impact on power and throttle response. That is where I went wrong years ago. I rebuilt my 02 kx125, but I never cleaned the power valves and it definitely didn't have the power it should've for a fresh rebuild because that really does have a huge impact on several different things.

An excellent video.

Nice short!

Over time and with a lot of practise with rebuilds you get to know the feel of a tourqe spec, but its still wise to check your manual.

Missed a few very important steps! Never checked for proper ring gap, never measured the cylinder for excessive wear, never honed the cylinder to all the new ring to seat properly! Sure it runs but it could have been better just my opinion!

good work :)

I'm looking into buying a dirt bike, and was really unsure about 2 stroke or 4 stroke. After seeing how easy it is to replace the piston, I'm pretty much sold on a 2 stroke now.

2 stroke gang!!!

Professional..I had just picked up a 1982 Cr 125r.I have to say it's in very nice original condition.I am going to replace the piston,ring and top gaskets.Because of it's age and knowing it has tempered through it's riding hours I was told to put a very thin coat of good quality gasket permatex on them to ensure a good all around seal in case there may be any imperfection on the actual surface.I am not going to have it resurfaced on the head but clean it well and assemble..Any comment?

Always install the circlips with the gap facing either straight up or straight down. The force of 1000+ RPM will pop that thing out very easily. Otherwise, great video

Why is thos so relaxing to watch? :)

Nice movie thank for information

Most models u just pull out the rods and flap its basically a gate that opens and closes for more exhaust to escape disconnect the one side then pull the pin threw. As in cleaning it i would use contact cleaner or brake cleaner something to remove the oil. Make sure tho after u clean it lube it back up with some rawww premix. Next time if it dirty change your jetting or fuel oil ratio

i admit last time i did a top end that nut under the power valve cover i had to shave a bit of meat off a ring spanner, so i did not properly torque it back down along with the rest, luckily were i work now i have access to torgue wrenches that should allow me to use open end spanner bits to torque it. otherwise a standard socket torque wrench would not fit in there. ( hence previously just doing it up by hand with a modified ring spanner, untorqued.)

I beleive it's time for a fresh rebuild man! to me it sounds like there isn't much compression. Sometimes a bike will just barely idle with low compression, and once you try to give it some throttle it just loses all compression and trys to die on ya. I'm suprised it even starts.

it does. should be an arrow for the exhaust port. hope this helps

Nice vid bro
