Stamped to identify the proper parts.
I like to pre-oil everything before installing
new seals in place
Installing the valve springs. A little assembly lube on everything that has metal to metal contact isn't a bad idea, and it helps hold the little retainers in place. They're still a hell of a pain to place though. Also note back on the table that the tighter coil of the springs are at the bottom, remember this when installing them.
Old head on the right, it's interesting how much the casting has changed I don't know the build year for either but I would guess that the one on the left is newer. They're both from the same model of bike.
And this is why the old head's being replaced
New on the left. By the way when I say new I don't actually mean new, it's off the motor for one of my other bikes and almost as old but it's "new" to Loudbike.
Again, I've stayed up too late, and this is where I end.
