Hi! My name is Aaron! Im living in Japan (Hokkaido) and have just picked up a project bike, a non running gb250 for the low price of ¥7000 (about $100AUD). It came minus its carb, air filter box and muffler. Parts for this bike are really cheap to pick up here so Ive already got myself the carb and a supertrapp muffler. Im going to try and put it together first and see if I can get it running to assess what might need to be done. 2nd hand service manual for the gb150, even in Japan, are expensive and hard to come by. Some of the research Ive done tells me that the cbx250rs is very similar to the gb250. Would I be able to use the cbx250 manual in place of the gb250 manual? Also, is there a gb250 parts manual on this site? The plan is to strip and rebuild as a flat tracker similar to the 2nd photo posted. Cheers ! Aaron
