Idea: Closed Loop Throttle Body Fuel Injection

MiPasoMeEncanta · Post by **MiPasoMeEncanta** » Sat Apr 01, 2006 1:54 am

This is just an idea I wanted to run by everyone for their opinion. Since the Paso 750 originally ran a Webber automobile carburetor, would it be possible to adapt a Holley Commander 950 Throttle Body Fuel Injection System with an oxygen sensor (closed loop) that is adjustable via a laptop computer on to one? Imagine easy start ups and crisp throttle response.

My Paso has Mikunis and they are good. But the idea of my bike having a close loop fuel system intrigues me. Any other ideas or opinions?

You can see the Holley system I am thinking about at http://www.holley.com/950-19S.asp

You could certainly convert the engine to fuel injection, but I wouldn't start with the kit you've linked to. It's HUGE compared to what you'd want. Well, at least compared to what I'd want.

Unless you have access to a dyno and a lot of free time on your hands, I'd stick with carbs.

Need very many modifications to electrical system! Thats why i dont like that.... No matter, i am electrician and i have already many usefull stuff to that modifiaction. Earlier i taught, its easy to modify Pantah 750 Paso engine to fuel injected, but can U handle those pick up systems, timing, etc..... ??

Anyway, i am very intrested, if U start that modification

I Have Webbers and they can run and start quite sweet but they loose the tune quickly after set up.
I know little about this subject but how about the injector system of a Monster?

I have throttle bodies from 907, but that is only one easy thing, what is needeed to such conversion. Most problematic are electrics, timing, sensors, ECU, etc, etc.... But surely need also somekind throttle bodies...

The original author here. So it's not as simple as an O2 sensor telling the Throttle Body how much air/fuel mixture is needed with the idle regulated by the control box via a laptop (or even a screw)?
