So I ordered my brake parts as well as new pistons and rings, Valve lapping tool and paste and valve seals. I'm sticking with my original caliper (because it looks so pretty) I glass bead blasted it and i'm going to seal it with a product I bought called ShineSeal. I plan to leave it unpainted. I will definitely test it fully before riding. I also cleaned the cylinder head, I soda blasted the valve ports, then masked it off and abrasive glass blasted the aluminum exterior, then glass bead blasted to finish. I used boiling water to rinse (5 cycles) unfortunately the aluminum changed color again, I'm guessing its the heat? as the brake caliper didn't change when I cleaned it in warm water. I'm going to reblast with bead and try running it through the ultrasonic but with no heat. to the touch the valve seats fell smooth but they have a speckled appearance? hopefully when I lap them it will disappear. The question I have for anyone watching is regarding what I should do with the bottom end. I want to just clean it and build on top of it but it's such a mess. I cleaned with degreaser and a brush and it doesn't look like I did anything. I'm also worried that the main gaskets are leaking. Ideally i'd like to disassemble it and properly clean the cases but I don't know how realistic that is? I think i'm probably pushing my luck as it is?
