I own a '91 Beat here in the UK. Last year the cambelt broke and my mechanic mate (Honda) rebuilt the engine. Honda UK contacted Honda Japan who sent the Beat's factory details. Hundreds of pages! My mate was able to get exact settings etc. After the rebuild it started first time. He was surprised at how many parts Honda Japan still provide for it and he said that those they don't can be substituted. Non genuine, but good parts are available for major consumables.
