Part 8 is up!
Okay in my defense I kind of figured in the first episode that this would be quite an undertaking, so yes, I know, we're four months on, eight episodes in, and probably up to a couple hours worth of watching me fumble around what should be a weekend job for a normal hobbyist, but I did say I planned on being methodical
But hey, we're almost done. Hopefully I'll be able to cram the rest of the head assy/engine installation into the next episode
For a fun exercise, I made a list of all the things I still have to do on this bike before I can fire it up and go for a rip
Don't ever do that

Haha thanks well I am a nerd at heart. The next episode is the valvetrain, probably my personal fave. These lumpy motors don't look like much on the outside but man oh man, they've got some lovely guts, especially the cylinder head
Take the rocker arms. Here's a part that needs to be cast, machined, hardened, and polished, all within a very tight specification. They are tiny, but need to be tough, pushing against the springs to clickity clack down onto the valves once every four rpms. If this part breaks or seizes, immediate catastrophic failure. Some parts are overbuilt, and others are underbuilt. These seem to be perfectly built. You can see where the engineers added metal to make them stronger in places, but also took away metal from other places to make them lighter. Gorgeous part
If I had a spare I'd make it a keychain, but that'd probably be a waste
