Alright mate love the videos I have a problem with a 110 cc engine just rebuild the gearbox and selector is sometimes stiff also can’t find neutral soon as I remove the clutch assembly I can find it, could this be a possible cause for clutch basket failure

Kick it, like a "real" man...

That was awesome thanks. I learned a lot.

Do you have a break down video?

How do you take the clutch off if the piston rod keeps moving?

My bike doesn’t start that easy 😭😭😭

Hello,i have a motor like this with n-1-2-3-4 and i can t find the neutral,i changed the left cover

I know this video is over 5 years old and this guy may not even be living still but considering all the questions people have asked him with zero answers back he may have died right after he posted this video. Myself and half the other people that has comment would love to know where you buy the parts. But we arnt in no hurry so just let us know when you get the time. No Rush. Ok thanks

To much...

Hi, we just bought our own YZ400F but with the engine not completely installed. In this video we see you put a bullet on the shaft before putting the bearing on top (at 6:25). In no explosion drawing the bullet is mentioned. Whey do you put it in? Thank for your respons!

Before machining the last cube freeing cut, I filled the cube with molten lead, do the last cut to detach, then melt the lead out.

wow the gearbox is so tiny for such a powerful bike

Thank You! Gonna try this

Hey i got a question .. i have 2003 yz450f frame .... the engine from a 2006 wr 450f fit the 2003 yz450f? can you help me with this?

My bike is running because of this video I assembled my bike on my own and it runs perfectly this guy is the best may good bless this guy 🔥🔥🔥

You are the best keep on helping others like this great channel and upload 🔥

Very good video for education

So sad😢😢

Well understood

awh man ive been there, nothing worse than bolloxing it on the last step

Where you getting specific parts for these motors?

Figured I would see if you could possibly help me/ give me any ideas before I tear the 110 I just rebuilt back apart lol, I had checked the gears and kickstart lever as you had shown in the video, and they seemed to have been working properly at that point, but then after mounting the engine and putting the shift lever back on there is zero movement up or down, I more than likely assembled something wrong, but any advice would be great before I split the case again haha, Thanks Kindly and great videos!

0:53 what is the part name or part number

Did you fit the ignition and speedometer to the bike yourself or was this factory? I’m looking to put my mx bike on the road its the first time i’ve seen an ignition like this? Great Vid 👍🏽

Name of engine?

ฉันรวบรวมเครื่องยนต์มาสเตอร์ 100cup ได้อย่างสมบูรณ์ ทุกอย่างปกติดี เกียร์ทำงานได้อย่างราบรื่น แต่คันสตาร์ทเท้าหมุนรอบเดินเบาเมื่อกดคันบังคับ เกียร์ขนาดเล็กหมุนและลูกสูบไม่หมุน อาจเป็นเพราะสาเหตุใด

Not 125 this

ممكن تهدر وتفهمنا موش ادير موسيقه

And does anybody know the engine code for this model ???

I have a bike with this engine. And when I try to kick her over in neutral the kick start just drops like its not engaging, I can cycle through all the gears and when I kick her in gear on the workstand it engages and the back wheel spins. The clutch is fine and everything else seems A ok. Do you have any ideas for a fix before I split the bottom end. Any thoughts would be greatly appreciated 🤷‍♂️

Where did you get the parts?

Is it ok if i hear the rattling noise when testing the kickstart?

1:45 where Do you get that o ring?

Great video. But when is put my engine in neutral I hear a rattling noice coming from the kickstart assembly, when I press it in I don’t hear the noise anymore. Any tips?

You forgot to mention that your going to need to removed the header pipe just in order to reach the oil filter
