Guys don't you think he knows what he's doing here. People comment like grind the ring to gap and cylinders don't have to be bored for that or you gotta measure the bore to piston gap. I'm a diesel mechanic working on trucks so I haven't done anything like that but I saw motorcycle guys fitting pistons in bores for two strokes by doing same resizing the bore and no measuring only fitting the piston and working it by hand like this and do it by feel. Only he used machine with a vertical set up and using a cutter not not sand paper on mandrel. I used similar machinery with horizontal mandrel for reeming steering knickle bushings for king pins for heavy trucks. Well that guy guy says that piston gotta be kinda almost dragging on the bore and barely almost not fall through the bore dry. For that two stroke aluminum shit cylinder made on Russia or it was chinese which probably even worse. And during break in the piston and ring would work utself into material for it to run gpod for long time and not rattle around right away. Only he gapped the rings after or picked right one. Anyway the oil there is giving him a gap good enough already and he knows by feel after doing it many many times around. And did nobody notice the ring gap shape itself in this video? It is not straight cut but S shaped therefore I conclude that this guy knows what he is doing here and done it before. Unlike most commenters here. 😊

So for ring gap they bore the cylinder instead of filing the rings. Thats a new one to me

Work super

Технологию машиностроения, никто не отменял.. 1, Цилиндр подгоняется под поршень (легко опускается под своим весом) 2, Кольца подгоняют по цилиндру, в соответствии ТУ зазоры. Цилиндр растачивается на станке, чтобы исключить элепсность и хонингуется в размер по поршню. То что он делает, заклинит, через 10мин. Тепловые зазоры обязателны, физику не обманешь...

Tá bom! E a goleada do aner? Teria que aquecer todo o cistema para ajustar. Por isso que quebra tudo.

يسلم عليكم رائد من العراق❤يكول ماتشغلوني وياكم😊

Backwards. Bore should be sized to fit piston. Ring modified to have proper gap in bore

How many cc?

Magic fingers! 😂

Not America.

Как так можно на глаз определить зазор? Похоже на альфовскую поршневую. Там зазор должен быть 0.09.

Необходимо колечко подточить

This "shop" is *_FILTHY_*_ _*_!!!_*

Все. Время покорять космос

باعرض سلام خدمت استا عزیزم این روش پولیش سیلندر کاملا اشتباه است

Lucidatura cilindro .......,🤔 Ellittica.

Это просто уже элирс при такой шлифовки нормального радиуса не зделать

First off. This is a four stroke cylinder. People dont copy this as most cylinders for bikes are nickel seal and if you sand it out to suit ring gap ur mess up the cylinder. This must be a cheap Chinese steel liner cylinder or something! I do not recommend doing this.

Масло кране канцерогенное, это смертельная работа.

Длжен быть тепловой зазор

Как без зазора

Нет теплового зазора поршневого кольца... Брак

It's not the cylinder it's the freaking clip that's needs grinding there's too much of a gap there that 4-stroke isn't going to run for very long having gas going to that Gap will only wash the oil off the head scratching the head making the motor garbage

Щуп? Нет, не слышал!😂

Проще кольцо подточить!!!!

Der weiß schon was er macht. Sicherlich wird der eine gute Kompression haben

Then without washing his hands, he's out making sandwiches on another video.

Masih seret itu yg benar seher jalan sendiri/gravitasi

😂😂😂😂😂😂говно это всё

щуп и нутромер тебе в помощь😂
