Hey Bill I take it from the Rising Sun Hinomaru gas tank you are planning on joining the Bozozoku
The Rising Sun, Nisshoki, fuel tank is on a long term bobber project that is being built from a combination of TT500, SR500 and various other Yamaha bits.
Here are a few shots of the fuel tank;
In my limited understanding of Japanese, Hinomaru is the Japanese National flag, and Nisshoki was the Japanese Naval Ensign as used during WW2.
The calligraphy are the Kanji characters for Jinrai (Thunder God / Thunder Clap), which will be the name of the bike when it is finished.
