Digital Fuel Injection on latest Jetsurf 2 stroke engines

[Freakie]

Hi guys

This is likely a question for the carb tuner peeps and everyone else who know enough about this subject to offer insights. The newest Jetsurf motorised surfboards since 2021 all have DFI fuel injection on the 100cc single 2 stroke engine....its basically a small jetski and I was wondering how they pulled that off when no-one could really perfect it for our sport ...Also...the US is a big export market for them as the emissions are below the legal requirements.......any insights most welcome.

Standups and smaller craft are the only PWCs that need a light weight engine. Bigger/heavier fourstrokes are fine in the giant couches that customers are actually buying. The SXR1500 is like riding a torpedo and the new Superjet just left me confused..
