I bought this bike as a parts bike 2 years ago out of michigan. Started using parts off of it for my project (got a straight unhacked titled frame) and since my swingarm is getting worked on (I dont weld aluminum) and I am waiting on wheels I decided to tear into the mkii engine I set aside from the Michigan bike.
When I bought it number 4 plug was broke off flush with the head, I drilled it out with a greased bit and retapped, then blew it out thouroughly and since the spark plug threads were slightly wobbly I set it aside and decided that I needed to pull the head and threadsert it.
Glad I did, just opened her up today and boy that blowing out crap dont work

All four holes are good and scratch free though; just gotta strip that crappy black paint off of the entire engine... And that's gonna take a while.
