Looks great Johnny.
Quick bit of advice:Get yourself some cast-blast in a rattle can,spray it into a small container and brush it onto your master cylinder carefully.You won't even have to remove the lid,just remove the snap ring and work slowly & carefully.Since it's a cast finish,it'll look very professional after you're done.
You know how the eye always goes to the only defect and man...there's not much to fault with your ride man...
5 minutes worth of work will pay off handsomely...
