So after 3 solid days of wrenching she's back together with a nice undercut gearbox and fresh cylinder head. I had to hand lap some of the valve shims to get them all within spec. The best part of cylinder head work is drinking beer. I just need a link for the cam chain and I can put it back in the chassis. Then it's just a matter of bolting all the bits back on the bike and ride it. Fuck Yeah.
