stab in the dark but it looks like a loncin to me. the side plate on the stator case looks the same that companies get stamped with their logo or they come with loncin written on them. can see it has a starter motor so i would guess something like a loncin 250cc chucked into a pitty frame. what brand is the bike? in the first pic crank case u can see a brand name of some sort but its hard to read

on engine is wrote DARING. This motor is 125cc 4 stroke.

so this D8EA plug is a match for what was in it previously ?

how do you know its getting to hot ?
whats the plug look like can you post a picture please

Going by the pictures on the bike have you just recently got this thing ? its a bit rusty and im suspecting you issues will be more old fuel in the carbi blocking the pilot jet.

If i drive a bit longer and take out the spark plug it is really BLACK at the top....i think i need more powerful spark plug(more heat value)...sry for my bad english

generally a black plug means its running rich, or theres oil on it thats being burnt
