Fule Injection?

[deadly]

Man that would be trick. I've often thought about that but theres so many variabiles of cc,strokers,pipes,silencers that it would be hard to have a bolt on system. Then to find a responable place to help you dyno.

There's no way it could be a bolt on and go system. Absolutely right about the variables especially cylinder and exhaust temps when you're actually out riding it. It would be much like dealing with a carb where you'd have to "field test" it and make the changes accordingly. It's almost scary because everything is based off old data to get a person close on jetting and no one has jack squat on this with a 250R. Not to mention $1300 is a FAT chunk of change to drop on this. As far as powering this I'm curious if a person can buy a high power stator, wire in a rectifier and capacitor to hold a charge to power the computer module or if you HAVE to use a battery? I'm going to speak with him next week. I mean no disrespect but I kind of think he has no experience with a 250R. In theory it should work just fine, but that is a metric shit ton of money to put out there with a HUGE "what if" factor.

Now don't quote me on this but I "think" he either has or is developing an app for the phone to remotely tune via a phone app and/or the ability to simply attach to your home wireless network so no cables are involved.
How awesome would that be to be out riding and say, "Gahhh it's running crappy hold on guys" and whip out your phone and re-program it.

Back to that price tag - yeesh I dunno. Do any of you guys or gals think you can pony up that much money and do you think the benefit out weighs the cost? I''m reeeeaaallly on the fence about this one.

For sure its not practical at all. You won't see me with one. But if I hit the lotto its going on my list.

I'll stick to a carb, but maybe if I hit the lotto AND all the bugs were worked out. It won't give you any more top end power really, but will help with the low end a bunch. Look at all the new 4 strokes with efi, they just kind of flatten out on top and still keep building revs, but no more power. Idk if that would be the case on a 2 stroke. The only real info on how well efi works on 2 strokes is in the sled market. The technology is out there and your 2 stroke will burn cleaner, with more power than the 4 strokes, but no one is releasing it for the quad/motorcycle market.

I don't know about High Gains kit but the guy from big bore motors with the efi banshee said the throttle response was awsome. He has done a 250r back in 03. I talked to him about doing mine a while back and you can tune it from a lap top or smart phone. that's sweet. It won't give you any more hp but it will give you a quicker throttle and alot more low end. efi on a 2 stroke is the only way they could ever make a come back or be competitive again on a atv.

[mennis1971]

I agree with you there doug. It IS the only way they will make a comeback unless/until the all the quad/mc buyers get sick of their new 4 stroke grenades and quit buying them which I really don't see happening in the forseeable future. I think that KTM and BRP are the only hope at this point in time, but why would they produce a new machine that the AMA has oulawed for racing. I think the AMA and the EPA are the real problems here. The OEM's are out to turn a profit, which I'm sure they are seeing due to increased parts sales, but they WILL quit making nothing but 4 strokes if/when the public refuses to buy them.

If they come up with a DI system like the Etec outboard engines and the SkiDoo sleds have then we have a chance. The system is compact and has been proven in the field for quite some time. Actually it's been on the outboards since 97 as FICHT and I believe there was a company in germany that developed it before that?? The DI system will benifit the MX guys and the GNCC riders too in that the system allows the engine to run efficently at lower rpm's and never load up. Plus with a quick MAP load you can tweak the system.

I think the problem that comes into play besides the AMA is the cost. The parts are there, that's not an issue but will it be another $10,000 quad??? You can build one heck of a quad for $10,000!! Now if it were $6000 that's a little easier to swallow.

I'm just waiting for someone to fab up the Etec setup on a quad and see the results. Now, if one of the manufactures come out with a DI dirt bike in the near future, run it in supercross and win....then we'll start to see changes.

On a side note...went to the track yesterday to watch the bikes practice and saw to 4 pokes sieze right in front of us almost back to back!!! The Dads were Pissed!!!

did these guys ever do an update?

[deadly]

I threw a few emails back and forth with him yesterday. For you guys saying it won't add HP ........ you juuuuust might be wrong about that. How much "more" is really the question.
I quote:
"I will guarantee higher horse power on anything you install it on. Calibrations can be changed in seconds rather than re-jetting or switching out carbs. We can literally switch from 87 octane fuel to full methanol in 4 mouse clicks through our global fuel calibration.

Our Port fuel injection system runs better than any carb setup under every condition you could imagine."

Would be a pretty cool set up but with so many differnt ways a 250R can be built would make it difficult to have a fuel cure for everyone.
