it would be a stupid move for honda imo,,, the kfx and ltr having it, it would be a risk not to, as yamaha might put it on there quads aswell....honda will be left in the dark.

my view on it, it will be some changes to the current 06,07 model minor tweeks with a added efi.

RFI = Radial Flash Induction

It's hard to explain without getting too deep into fluid dynamics. But it has to do with the cylinder head super-heating the intake air to just below the radial flash point of the nitrogen in the atmosphere.

You've probably never heard of this because it's a fairly new technology. But as mentioned, Kawi and Suzuki have been pioneering this field for a few years now.

I honestly wouldnt be surpised if there was no EFI. I think you all are jumping the gun assuming honda is going to take the plunge

I've yet to find a Salesman at a Dealership that knows which way North is. I can say that I sold myself my last ATV and educated the Salesman about it's finer points.:p

very true. my dealership knows jack **** about any of the quads. i've been looking for a new one and i end up telling the guy all about the quads.

Dont forget people some of honda utility quads are currently fuel injected. The sport quads arent far behind as well as the crf dirtbikes being fuel injected.

This is old technology(fuel injection isnt a new idea) being applied to new applications. I personally cant friggin wait to tune my quad like i tune my turbo car.

right now its like predicting a football game, you can guess what will happen but until its out WE wont know much.

my guess is the 08 gets a little lower center of gravity, they keep the 06/07 rear susp. and bring back the 04/05 front geometry.
and I efi will be on it (and offered as a retro fit for the 06/07)

new graphics/frame colors maybe hooked up with tag/flex bars stock.


post your guesses and see who gets close ?

I just hope Honda stays smart and keeps a carb on the bike. Last time I checked the fuel injected bikes aren't blowing away the competition like everyone seems to assume. Honda is still sitting on top of the podium without a fuel injected bike.

Honda is very well aware of changes but for now its speculation.

If the 08 has EFI, I'd guess the chances of an OEM sponsored 06/07 retrofit would be 0%.

I've worked on, been around, and ridden both Rap700s and LT-R450s. Not to mention umpteen hours of tuning on all manner of carbureted ATVs. Based on my experiences, I look forward to EFI. There's lots of things about carbs I like--I'm not put-off by them at all. But as good as state of the art carburetors are, EFI is "superior" in some ways. Sometimes "superior" just translates into different. In other aspects, "superior" literally means superior.

I will Second that:D :D I had a 1993 arctic cat wild cat 700EFI and that thing was great. ran like a top all the time,peaple were changing jetting all the time for the temp but not me.even when the motor was modded the EFI just kept the motor rocking, I look forward to EFI, I wish my TRX had it. But thats just my 2 cents.:D
As far as dirt goes a good air filter and then it doesn,t matter. the computer for these bikes is no more than a fansy CDI box.

If the 08 does have EFI, I hope the electric starting problems are fixed. If not, I'd rather have the carb and a kicker. I'm about to roll my 06 off a cliff and collect insurance because of the starting problems.

i pesonally could care less if honda comes out with EFI next year. i think its the future and will be what all quads have eventually, but i don't feel like the EFI quads now are truely that much superior. my friend has a LTR with an EFI controller and it has been a pain to work with for him. i have no problem with the way my 05 runs with a carb and will likely keep the quad a number of years unless something comes out that i just feel i need. plus having a carberated quad is much easier to work on in my opionion. just looking at the LTR makes me not want to dive in to it and fix anything.

the efi makes the quads start slower and more inconsistant spince. the zuk and kawi are both slower then the yfz or kicker trx

I think they need to take a 07 kicker, start with 04-05 spindles and actually improve the handling over them, do something with the rear linkage/suspension, a dual piston rear caliper would be nice, beef up the tranny and bottom end a lot, and work on the frame etc. Basically take what they have and listen to the complaints. :D

one of the cool things of efi would be if you pull the airbox lid or put and exhaust on you dont have to rejet, just put it on and go.

also some of us would like to turbo the things and you pretty much would need efi to do it too

I read where the 08 CRF's are supposed to have FI but I think it was only in Japan and maybe the US in 09 or 2010. I bet the quad will get it first.

That is true only with closed loop EFI systems. Open loop EFI systems (like those found on most motorcycles and all ATVs) only adjust for environmental conditions, not engine modifications. When EFI arrives on the 450r some sort of add-on EFI management device will be needed to tell the EFI about the presence of intake/exhaust modifications.
