Amazing and interesting video this time! I found this one very interesting in how engine came apart! 👍

[@gdengineering-restorationv2113]

Thanks glad you enjoyed our latest video and we changed it up this time!

[@dreveneuhlie7167]

nice job i found wat i was loking for

[@homegrown_lonewolf]

Whenever you get one of these engines, completely disassemble it and reassemble with locktite. They are thrown together at the factory and there is usually a leak somewhere.

Glad to watch this video...40 pounds is worth for this real 2 stroke engine....I cud not understand the spark plug working here...u had shown some electronic circuit I guess that cud be cdi unit...gr8

[@xptics]

it’s got a magneto on the flywheel that with magnets makes it send an electronic signal to the magneto and through to the spark plug

[@joseantonio4901]

é porisso que eu gosto dessa profissão,que vídeo legal...

[@bpprojects6676]

Interesting change in restoration! Loved it guys good work!

[@gdengineering-restorationv2113]

Great thanks!

[@chrisharm6242]

How do you get clutc springs back on to reassemble? It’s kicking my ass!!😂

[@gdengineering-restorationv2113]

We used a pair of pliers that we were able to clamp down at certain points making it easy to put the spring back on. Hope this helps :)

[@chrisharm6242]

I got it , thanks

[@keithd9705]

Brilliant thanks!

[@gdengineering-restorationv2113]

Your welcome, all the best :)

[@danrr1197]

Wow another great video with a different theme! LOVED IT!!!🔥🔥

[@gdengineering-restorationv2113]

Thank you!!

I put a 50cc Honda Postman bike motor in a pocket bike and it goes 4x as good & heaps faster than these 49cc elcheapo Chinese things. These 49 cc jobs overheat real quick and their carburetors are rubbish, but these motors only cost $50 to $80 bucks brand new, so they are not bad for the cost.

[@winters6271]

Think you could add a 70 cc kit to one of these

[@adilhossain227]

Hi, I have a question, does these engines need engine lubrication oil ?

[@gdengineering-restorationv2113]

The oil is mixed into the fuel, ratio of 5:1

Hi there I’ve just brought one of these engines and it’s really hard to pull.I can lift the whole quad bike up with the pull start do you have any idea what it would be???

[@pietercoetzee6253]

I have the same problem. Anyone have any ideas

[@wave_4204]

@@pietercoetzee6253 hi i know this is a bit late but i got this engine and i dont have this problem its been 5 months since your comment so maybe they have changed this

[@Foppa905]

Ur engine probs siezed

[@mapogt]

How do you change oil to that engine?

[@gdengineering-restorationv2113]

The oil is mixed in with the fuel. Ensuring well oiled engine components, however this leaves alot if smoke in the exhaust fumes

[@mapogt]

@@gdengineering-restorationv2113 Is the crankshaft lubricated with the same fuel oil mixture?

[@gdengineering-restorationv2113]

According to the manufacturer, and personal use. I use a separate lubricant for the crankshaft however the oil/fuel mix does lubricant it throughout its use

[@mapogt]

@@gdengineering-restorationv2113 Thank you for answering! Is there somewhere that I can find a manual for this engine?

[@gdengineering-restorationv2113]

Not a specific manual but if you use KZbin videos people pretty much should the ins and outs of the them. Since they are all very similar

[@AfzalKhan-lk4wj]

Hi

[@somtingwongwai7194]

I thought about doing this but found they are selling them on ebay for $50, so i didn't bother

[@Blake_Guajardo]

What is an actual name or brand of these engines

[@gdengineering-restorationv2113]

There isn't a specific brand we used however you can find similar ones on eBay

[@Yukanhayt-Mhenow]

MADE IN CHINA is the brand bro.

[@jamesbarr6465]
