When do you think Kawasaki will release the Teryx with fuel injection?

I think the dealer said somewhere around November.

I will be interested to see what it would take to convert a standard carburated motor to the new EFI when it is released.

You would think so, however, I have heard this is easier said than doneWhy don't you just order the sending unit, computer, and intake for a Brute force and install it on your teryx?
Should be an easy fix.
What I don't understand is all the hullaboo about Fuel injection from the factory when to make it work with mods, you have to add a controller box to adjust for mods.
Until the factory does REAL fuel injection with O2 sensors in the exhaust that will adjust for changes in real time, I'm just as happy with having a carb setup. Having said that, I really want the Air/Fuel Ratio Gauge setup to make jetting a lot simpler.

the latest i have heard is 2010 but i dont know.
I don't know much about FI but from what I have been reading I feel the same way.
Is the control box that you would have to buy the same one that you can adjust timing curve too or do you need to have 2 seperate boxes with FI and Timing?
I would almost thing you would have to retune at least a little bit since this system doesn't work like a car FI does. Unless the Brute comes in extremely rich from factory?
I don't have neither the Brute or Teryx. I am just doing research for possibly my next purchase so all my info is not first hand experience.
I don't know if I have said it before but nice site. :wave:

Doug, I am 99% sure this is not the case with the Brute Force as JoeDirt mentioned. It is not EFI like in a car where there are O2 sensors on hte exhaust and the EFI computer is "smart" and adjusts for all those things. Granted, you will have nice throttle response and easier starting than a carburetor, but it will not adjust for extremes like opening up the airbox or exhaust. That's why the aftermarket makes EFI controllers for ATVs/UTV's.
That was my whole point about the current "dumb" EFI systems, and my wish that they worked as they do in a auto applications.

"Fuel injected 90-degree 749cc V-twin engine
- Digital fuel Injection provides the perfect delivery throughout the rpm range with fast throttle response
- 36mm throttle bodies are controlled by a 32-bit CPU, which monitors coolant temperature, air intake temperature, throttle position, air intake pressure, vehicle speed and crankshaft angle to help ensure the perfect air fuel mixture"
Not the same as a car EFI off the O2 exhaust sensor. It is from my understanding, its before combustion.
That being said they have FI controllers for a reason. Aftermarket CDIs and carbs work well, just need to be set up properly.
Having having the carb version 750 Brute Force and my friends having the 08 with FI, the larger carbs and FI is a lot less finicky adjusting for altitude, temperature etc and has a little better throttle response.
Carbs work good once set up properly but jetting a Brute is a pain in the b*tt, especially if you ride in big temperature extremes (-5 below to 85 degrees) and altitude (2000 feet to 10,500 feet above sea level) during the year.

Oh yeah, I understand that it works fine if you leave it stock that it will adjust for altitude, and temp changes and such, If you ride in extremes I can understand that EFI is nice, but I don't want people to think that they can just add exhaust and open up airbox and think the EFI will adjust for the additional needed fuel, as it is my understanding it will not and you will be running dangerously lean and see less power not more with the mods.
I'm just amazed no one has taken an A/F mixture meter, tied it in with an aftermarket EFI controller and did it like the cars do with a O2 sensor built in to the mix. If they could market one of those for around $500 per TBI unit I bet they would make piles of money...

Generally if you increase flow (air or exhaust) you need to add fuel or you will be lean. Most after market companies will tell you that you have to jet up or change the map with a fuel injection controller (they often have dynoed it and you get the map with the aftermarket part). FI sure is nice for the people who see big variances in thier environment. Once the map is changed for performance accessories, it is my understanding that it should adjust for altitude and temperature better than a carb model.

Jaybo, somebody does, Dobeck. The problem is the set up would run you about $700 with the fuel controller and the o2 sensor set up then you still would not have anyway to change the timing.
About all those sensors. What is programmed in is this: When sensor 1 says this and sensor 2 says this and sensor 3 says this then do that. If one of those values changes it does something different. This is what is called a fuel map, no to be confused with a MAP sensor which is a manifold air pressure sensor.
There is a sensor that measures atmospheric pressure and that is how it knows you are changing elevations.
To make a learning system would be very expensive.
There is not a sensor in the present systems to measure air/fuel ratios so when you make a big change such as exhaust air intake came piston whatever it does not know what to do and most likely it will run lean until you put a controller on it.
Like I said, on this V-twin if you can't change the timing then there is not much use in fooling with the fuel.
Please no one get confused we are talking about the future fuel injected Teryx or the present Brute.
