Let talk about valves…
As you can see in the below picture, my cb450 valves were all sorts of f’ed up.
We determined that the piston must have burned up a hole in itself and the aluminum burned onto the valves? I guess? I could not get the shit off no matter what I tried.
Remember this is an extra head I got on eBay so I really didn’t know the condition.
So, Ricky had a tip to get the shit off the valves. He suggested muriatic acid to burn the aluminum off of the steel valves. It def worked great. Thanks Rick. Took a while and pretty sure I have cancer now from the fumes, but the valves seriously look like mint NOS valves after a quick run on the wire wheel.
They should lap in great now.

Got the tail light on today. Looks pretty cool. I’m psyched. Now all that’s left on the seat is to sand down the top, and coat it with Boeshield T-9. Seat pad is at the upholstery place right now getting made.
