"bad news they have a ton of parts... so many parts"
All those stripped JIS screws, tiny oring seals, gaskets that have to be NOS or they won'r work right, 6V/12V heads, valves, UGH. . very expensive.
People just stick lifan's on them, but even they aren't cheap, and have random quality control.
For being the most common vehicle in the world, ordering parts and paying for them sucks so bad.
