My kitten had a chaotic April… I was exhausted with things outside of work (\uff1b\u2200\uff1b)
Anyway, it felt like a proper Golden Week, and I got most of my homework done.
Since parts haven’t arrived, I’ve been organizing the shop and working on things I want to do with my own bike.<\/p>\n\n\n\n

Finally! I retrofitted a Zephyr 400 CVK30 onto my GPZ550.<\/p>\n\n\n\n
