There is no "kamal" of PakSuzi, in fact Japan factories have stopped churning out old carby 3-cyllinder engine due to strict envirionemtnal emission standards long time ago. PakSuzi was using this junked engines bought as scrap.
The so-called new EFi engines offered in Cultus now, probably were being thrown into Pacific ocean, but PakSuzi got them on scrap rates to install in the Cultus. This is inside story.
