I am using Castrol 2T Race Full Synthetic oil.
Engine is broken in.
I put 30ml of oil into per liter of 95 octane gasoline.
Spark plugs keep getting fouled i changed 3 spark plugs already.
It says use 50:1 on the bottle. But i couldn't trust it since chinese engines need to be lubricated .
 
If it is running good, then ride it for several days before you do anything. After a week of riding, do a chop cut on the plug. ride as fast as possible, and kill the engine at top rpm and pull clutch at the same time. Pull the plug and examine. Got any pictures of your plug now?

I already replaced it i do not replace because i want, they stop working.
 
You can clean them and reuse them. A piece of fine sand paper and a can of brake clean will get the job done.
Can we get a picture or two of the plugs and the engine set up? It's easier to diagnose if we see what is there.
