My buddy Keven commented a few posts down about these guys making gas tanks cast from Aluminum, so I had to check it out this morning. Went threw every page in their blog b4 I noticed the translate bar on top of the page! Hahaha! Looks as though they have been casting seats and bird deflectors for some time now. Cant weight to see how they mount the Aluminum tanks. Good stuff from our motorcycle casting brothers in Japan! Go check it out!
