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.
