Do you change ur Spark plug yourself?

[flareon1982]

As Above. My Mechanic told me that to change the sparkplug u will need a certain number of turns to make sure that the plug dun break a hole in the piston. Is it true? I tried to DIY changing the spark plug and found out that there is some brown residue at the plug thread. Is it normal?

Mine is not at the tip of the plug that is wet. Its at the side where you screw the plug into the hole. those like screws thread there. If the website of the spark plug says that the plug your bike can use, means that if i tighten it too tight or too loose also won't break a hole in my piston right?

 

Pls help. Worried for my bike

Yes. It is the same gap as my previous original plug. IU24 Denso. The only diff is that i using iridium now than previous is copper.
