2005 CBR600RR Rebuild Project Vid#3 (Opened the engine ) / Motorcycle restoration

We got the engine open, found one of the screws that hold the air filter inside the cylinder no4; that's why it was locked. Looks like we'll be needing a new piston, new spark plugs, new valves and/or a new cyl head.
My first time attempting to open and rebuild a locked motorcycle engine. Video was filmed mainly with the purpose of having reference and order of parts taking off as I have never attempted such a lengthy restoration on a bike. Hopefully I can revive this bike, and most importantly learn and have fun in the process.
DISCLAIMER: I'm not a professional, or a mechanic, or even a technician for that matter; I'm a guy that enjoys taking stuff apart and putting them back together. This is not by any means an educational video, this is just me braking stuff, laughing about it and then attempting to fix them. (hopefully together, and hopefully successfully)
