BeRAD I LOVE your stuff

BeRAD you should put a fmf gnarly pipe on the 250

rather easy to inspect a 2 stroke via the exhaust port before pulling the whole thing down.

Peter Taylor or a simple compression test will tell the story

And don't mean to be a keyboard warrior but if your just doing a piston change you don't actually have to take the head off, just save you a step and some time

My brother and I laughed so hard at your Swedish police video! We could just see the awkwardness.

BLDH SQUAD REPRESENT!!

In your van van?

BeRAD sick stuff

I have old 250 ktm and it has nice habit of dropping piston skirt in the block between 50 to 80 hours did that 3 times whit forget piston so is started to replacing piston every 50 hours it is a lot easier and cheaper switch piston than replace bearings, rod and balance it every time. but even that does not help if you forget to switch jet and go flat out -30c temp got nice hole i my piston and rod is nice and blue about half way down

that's no rebuild it's a piston change

When you take something apart and put it back together, its called, "Rebuild" It doesnt matter if you replace shit or not.

VroomVroomDana a suh dude!

#pussysquad !!!

VroomVroomDana i have around 50-60 hours on my 07 yz265

hahahaha truuuueeee

hardest thing doing rebuild is trying to not spill it everywhere :D

and here i am, thinking im just a slob..

At least replace the rings

Bruh why you do him dirty like that, this man would actually believe you and do it😂

Marlin Robertson yeah I should have while putting the cylinder on...I think it was alright though.

Generally it is but with an mx bike some dirt can get down there and splitting cases is not fun lol

You are right but usually the rag is for piston circlip not falling in the crank...

I have seen both happen but often dirt is harder to remove because you cannot pick it up with tweezers or a magnet

+Marlin Robertson I had to learn that the hard way, my brother and his friend we're taking apart my top end to check it, and my brothers friend dropped the circlip down the bottom endXD!

Yeah i noticed that too.

i think i saw him put the yellow powerband in. personally i like the blue powerband as it produces extreme top end power but still has enough low to mid range punch to giddy up when you need it. my mate put on two powerbands but only got an extra 50% more grunt.

billy liddy yeah I like the blue yellow mixed power band go really go with no 2 Stoke oil

I think I saw him put the yellow powerband on personally I like the “no powerband” one because it produces no power

that would have been a good idea! Luckily we did it without dropping anything haha

BeRAD yeah, we took my friends mopeds top end apart yeaes ago, and the clip went down, and then the upper rod bearing fell apart and all the damn bearing pieces fell down too. We had to take the whole thing off and shake it upside down :Dd

Georg1606 I dropped a piece of gasket and a piston clips down the crank it was so much trouble to get out

On my WR I dropped the valve shim down the head TWICE! Was able to get it out with a magnet but man was that scary.

it's scary as hell

was sure hes gon drop that clip inside the bottom end :D

I feelzzz

Smaeeeeeer

@@motofaija moi

Should have been riding instead of taking it apart. I love my YZ's. They will run forever if maintained properly.

Daniel Brown ahhh yes! Next time I'll try that thanks!

Daniel Brown Till it falls out 3 times and you get tired of it lol

Good way to wash the oil of the rotating parts 😂

Also making sure clips are either in 12 o clock or six o clock position so they don't compress and pop out with centrifugal force.

50 hours!!!! What a waste of time and money. And then reuse the most important thing!!! New circlips!!!! Dumb. My YZ's have been bulletproof for 20 years. I can hear when they need a top end and it ain't that often.

Werner Sunkel hey man my yz125 needs a rebuild , what did you do once you got to the power valve ? Only part I'm confused about

Also check the fuel cutoff solenoid in the carburator. There is a small rubber plug on the end of it that deteriorates and it is super prone to failure.

yoooooooooooo i like your video's man

Predictive is better, but preventative is better than nothing at least. And it's always good for peace of mind to check her out on the inside.

Mcjack57 some of us only learn the hard way😆 that's where experience comes from 😎

I agree I like 30-50 hours for top ends on, you Can never do to much maintenance. I’ve always done my bike/truck maintenance early. I recently got rid of my 250 2 stroke and got a 13 Rmz 450 1 owner a buddy bought it new, he did amateur racing. The bike is great for a race bike but I ride 80%% trails. Had a fresh top and bottom end rebuild a $1000 full titanium fmf exhaust and a lot of other good parts. I can’t wait to sell it and get back on a 2 stroke.I wanted to give the 4 stroke thing a try and my biggest complains is no e start 4 strokes need e start and first gear is to tall for trail riding also overheats trail riding and I’ve put on over size radiators, silicone hoses running engine ice and a 1.8 radiator cap the only thing left to do is a boysen water pump and the last thing I wanna do is put a fan kit on It, I was raised on 2 strokes and just prefer them for the riding I do my 2 strokes overheated maybe 5 times if that in 20+ years and multiple bikes. Then when it comes time for a top end kit I can build a 2 stroke for $200 but let my 450 blow and first I’ve never built a 4 stroke race bike and second the parts are double or more. I’m just a 2 stroke guy, I need to come off the cash and get what i want, a ktm 300 like the factory guys rode in strait rhythm 👍
