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 injecto=
r timing to be sure that they fire a the correct time,

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

Multi Port. - one injector per cylinder.=A0=A0 I thought the GEO/Suzuki "G1=
3BB" designation always indicated a MultiPort configuration. But I can't sa=
y 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 an=
d 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 cyl=
inder.
