This article is dated 20/08/2003. It has been 7 years that Yamaha have started to research and develop fuel injection system for small motorcycle. It have many challenges like sensors placement, compacting the injector module and how to make it use less electricity.
Now, we already have small motorcycle that uses the FI system that has been developed that is Yamaha X1R in Thailand and the first fuel injected bike in Malaysia that is Yamaha FZ-150i. Honda has been the first manufacturer that build the FI small bike by the introduction of Honda Wave 110i 125i with PGM-FI.
Anyone who likes to know about how FI able to be ported from automobile to small motorcycle or thinking is it possible to modify their carburetted bike to FI system, should read this article.
