Oh, are you sure it isn't a (typo?) 356cc engine? Also, I see that your website lists this car as a 1977, which is to say one year after the 2-strokes were no longer available in Japan. Looks like Astra Motors kept using old parts?
Was it assembled in Indonesia by P.T. Astra or was it Japanese built? I am very curious about the early days of the Southeast Asian Automotive industry, will be thankful for any (any!) further information you have to offer.
yes you are right, the engine capacity is 356cc instead of 365cc.
some parts still available in Jakarta's market.
