Yes, I will
I gave up getting a chain case cheap. (blue tank too I suppose)
Same with tank. I have 3 tanks, original K6 repainted in light red (my avatar), repainted scratched black 72-74, 74 with fresh paint in green with all trims, side covers.
It would be nice to get back the original blue as yamiya750 sell new for a price I saw as too high 1-2 years ago. Now no problems when I have searched a lot for 750 parts, new or used.
Only thing is that the tanks from Yamiya has the petcock in old style before 1975 on right side. (wrong for my K6). I can restore my original tank that I know have some dents and rust inside, it will cost to paint it.
CB750 seems to be very popular and prices rather high, good parts disappear quick.
My project to restore my old bike has cost me more than I planned from the beginning. But it's worth it. It take med back to my history I have had with it since 1979.
