Mike,

Thanks for the clarification.

My 1997 Geo uses a single injector in the throttle body.

That is why I was confused about the multiple injectors.

I guess that they went to multiple injectors in later models.

With the multiple injectors you will have to be more concerned with injector timing to be sure that they fire a the correct time,

Jim

>>Are you using Throttle Body Fuel injection or multiport FI?<<

Multi Port. - one injector per cylinder. I thought the GEO/Suzuki "G13BB" designation always indicated a MultiPort configuration. But I can't say I'm positive. Maybe that is just for the later years, 1998 and beyond.

Here is a photo of my trike, as it came from the dealer. The electricals and fuel tank are completely changed, but the engine is the same, and you can see the air intake. Behind it is the fuel rail, with injectors on each cylinder.
