Four. The parts catalog available to you at this site will clearly show four injectors.

Why the question if I may ask?

Ok thx. Just curious how to clean them or keep them clean.

I'd suggest using Yamaha's Ringfree.

IME, it works extremely well. I've NEVER had to pull my injectors or VST (F150) for cleaning (and that's 13 years)..

I also use it in all my gas powered machines/SUV and it keeps any potentially fueling issues at bay..
