250cc Dirt Bike Restoration/Rebuild - Zongshen 250 

I like the simplicity of these Chinese OHV Motorbike Engines.. it's basically a Honda CG 125 engine with a bigger displacement with extra bits and bobs for the electric starter

I love your video and i am inspired to make my own thanks im about to buy a apollo and get crazy hopefully i dont get overwhelmed with the mechanics but this looks fun

Its a old xb 31 nice china bike.. :)

good job dude!

素晴らしい👍

Nice job thease bikes are hore to work on congratulations

I like that engine stand.

superbe vidéo

Isso que é uma jegua Boa de se locomover

Hey Bro! I also have this dirt bike and it's amazing

I have a Xmoto 31 with 250cc and my engine looks similar to yours. Which cylinder kit did you use and what are the clearances for the valves?

CG model more durable and less maintenance. very nice video

Q hermoso

Looks like I've got the same question as many others on here. Could you please put some text or voice over on your video to explain what settings and specifications you actually set the engine to when rebuilding it. You showed me a very cool clip of you setting the exhaust valves, but that gave me absolutely no information on how to actually do it. The best reference I can find online for anyone else that reads this comment is to set your exhaust. 003 and your intake to .004 I've also found other videos on RU-vid that recommend setting them both to .004

Please can you tell me what gaps you made for the valves?

Can you show a tutorial on how you wired the motor up

I'm rebuilding my orion agb30 and still don't have spark. Waiting on the AC cdi and 8 post 5 wire stator. Went over most of the rest of the bike already. Still need to do a valve gap, forks. Mine has this stupid kill switch on the brake lever. Only 100$ in on replacement parts. Hope I get it running good.

Bro! Amazing do you have the book of maintenance?? Appreciate.

A very helpful leson.... But i need one of the spares of zongshen how are they available

where did you buy the plastics from? thanks!

I'm first

What plastic kit are you using for this build? I have one and need plastics to fit it

Hey. I have one of these and it's smoking from between the head and cylinder. Will that require a full rebuild? Also, I can't find a rear replacement hub to save my life. It's sheared and needs to be replaced.

Hello! from where did you buy the motorcycle parts?

Just wondering what plastics fit this bike? I have the same and need plastics replacing

hi bro! nice bike! I have the same one, it is shot 16 the rear and 19 the front. I want to put together the new front wheel and I don't know what measurements the spokes are to buy new ones, do you think you can know? because on one side they are long and on the other they are shorter. Thank you

Zongshen are awesome I’ve raced out doors on mine just started doing supercross training on it to hopefully race anahime 1 supercross since I took it off the dealership floor I’ve never had to touch the suspension or anything I actually sold all my tools cause I e never had to even tighten a chain or any nut on the bike I’ve never even changed an air filter an I’ve had 243 Gate drops an wins on it
