striped spark plug hole
so my carbide stalled and i checked it over to see the spark plug out, when i went to put it back in the cheap cap broke so i went out and got a new NGK racing cable (all they had) put it in and after 10 min. of riding it happened again put it back in and it shoot right back out from the compression.
So what should i do new head, tap and helix coil , tap and bigger plug?
Another question are these heads aluminum coated?
