Yr CB400s looks nicer and nicer.
Just a trick on the black colour at frame and also brake, trick that you can use black nail-paint to touch it up.
After dry nobody will tell the diff.

alu bolts are nice, but I like the real stainless steel bolt. They are strong and last forever!!!!

New rear shock look great and colour match. However the stock Showa is much better in performance, also Ohlin but kind of big bucks.
Clean inside head light and lens, once it is very clear the bike will look like new bike.
