hey guys i really would need some help on this. I have a 2000 cbr 600f4 that needs the head to be tapped for a spark plug to fit again.... i wanna go either helicoil or time sert but i’m curious and confused on how to get the tap inside the spark plug hole with enough sticking out to turn with a ratchet. I don’t want to take the heads off to be honest i don’t have the tools for that. i’m sure grease will work fine pulling the chips out and then i can vacuum out the rest. Any help with this will go a long ways thanks.
