My 2005 EX-250 with fuel injection....

This project started out as a "what if" that turned into a self-imposed technical challenge/quest and ended up eating my spare time throughout late October and all of November. It's done, it runs, and now all I have to do is slowly perfect the fueling tables (with my laptop computer).

Here's a tour of the bike. (It was 32 degrees F in the driveway this afternoon and I was so cold I could hardly think or talk, so bear with me).

Nice piece of work Greg - this is going to get a lot of hits and questions. Was I reading the ODO right ~9900 miles on your '05?

What gave you the urge to take on this challenge?



Keep us posted on the tuning.

Yeah, it hasn't reached 10,000 miles yet.....

....but it's not my fault.

I bought it in the summer of 2007 with 3,600 miles on it, so I've only had it for two years. I don't get to ride it every day because I travel a lot in my profession(s) (airline pilot, air national guard pilot).

It was owned from new by a woman in a nearby neighborhood who teaches 9th and 10th grade math at the local High School. She broke it in carefully, didn't ride it much, never dropped it, and had all the proper maintenance done on time. It was always garaged and lovingly washed and waxed.

I couldn't have gotten a better deal when I bought it.

She didn't want to sell it, and actually got teary-eyed when I paid her for it. Her husband wanted a big expensive Liter-bike and the money from the EX-250 sale was obviously going to help finance it. Her part of the deal in this Liter-bike action was that he was giving her his old, road-rashed, broken-fairinged, mangled-levered, dented-exhaust canned, Super Sport 600.

Over time I probably will....

It would be neat to watch people take my example and improve upon it. Because you know there are guys out there that could do it better. All you have to do is show them the "box" and they'll "think outside" of it.

If it's acceptable to the moderators to put it up, you could go here

Nice work, Greg. I may have to do mine now that you make it look so easy.

Someone else used the MicroSquirt on a turbo'ed N250:

O2 sensor

The sensor itself is a Bosch LSU 4.2 (5-wire).

I plumbed it in with an extended-length bung to avoid restricting the relatively small-diameter exhaust tube.

I'm using an Innovate Motorsports LC-1 digital wideband controller and a standalone guage.

Greg,

Assuming you had to buy all the parts for this and could sell off your used carbs, approximately what would the net cost would be? Also, how much weight would it add?

What kind of horsepower and/or driveability gains are there over the stock carbs? It'd be interesting to see hp / torque / AF graphs for the same bike with well-tuned carbs vs. a well-tuned fuel injection system.

I love to tinker and have already upgraded the intake and exhaust on my bike and started doing some minor weight loss / aesthetic mods, but I just wonder about the cost vs. the benefit of changing the fuel system to FI.

From a black box point of view, it would be nice not to have to fiddle with a petcock or choke lever, but what about the performance out on the road?

At this point it would be tough to go back and reconstruct a full-up listing of the cost for each item. I wasn't exactly keeping track as I gathered the parts and did the work, plus some of it came from a friend in San Antonio.

Just a wild-assed guess would be somewhere between $1,700 and $2,000 all-inclusive (if you want to count the 2-into-1 exhaust).

I didn't give much thought to money while I was doing this. It was "mad money." Just discretionary spending.

The only weight issue was how many pounds the bike lost when I got rid of the stock exhausts and the center stand. I would guess the injection equipment doesn't weigh but a few pounds more than the carb equipment (just the fuel pump, pressure regulator, and fuel filter are "extra" weight compared to the carb version).

As far as power is concerned I haven't gotten the bike to a "full power" state of tuning yet. The weather has gone snowy here in Spokane so riding has been impossible lately. But even in it's "rough" state of tune the bike feels at least as lively as the carburated version.

I think it's going to be great when I get it dialed in. I know a guy who injected a Honda CB-750 and it's throttle response is absolutely razor-sharp.

The warnings I would give to anyone who might even think about doing a fuel injection project are as follows:

Don't do it if you need your bike for daily transportation (it takes a while),

don't do it if spending money on your EX-250 bothers or embarrasses you,

don't do it if anyone has ever accused you of not having enough patience (because you're going to need a lot of patience just to get through the wiring process),

don't do it if you get frustrated easily,

don't do it if your wife or girlfriend gets jealous of anything that takes up your time.

I'd love to do it and I'm sure I'd appreciate its advantages, but I think it's just the cost that's got me turned off a little. I wonder if it'd be any cheaper to get a hold of the rest of the foreign-spec FI goodies like you did with the TBs and then just graft those into a US bike... Any idea what kind of flow rate those injectors are spec'ed at?

I hear you about the snow. We just got 13" between yesterday and today.

Next projects are an Acumen gear indicator and repaint, but I'm keeping FI on the possibilities list...

Keep us posted on any updates.

The injectors, which are from the European EX-250, flow about 210cc/min at 43psi. This is my estimate. I figured this out by running injector flow tests after I had all the equipment installed on the bike.

I couldn't find any specification for EX-250 injector flow rate available anywhere on the web or in print to tell me this. I guess Kawasaki doesn't feel that anyone (beyond their own engineers) needs to know this information, because injector flow rate isn't a statistic that would impress the average sportbike buyer or sell more bikes if Kawasaki were to publish it. Also, the injectors are built in Japan under license from Bosch (they're a Bosch design), and they don't have standard Bosch markings on them (which can normally be looked up to learn information like flow rate, max operating pressure, and whether it's high or low impedance).

About the money issue: I believe that we all have things we blow money on just for fun. Here's an example of the problem this causes. I've got a friend/neighbor who smokes a lot (and I mean a LOT) of weed. This guy will (quite regularly) stand in my garage (usually after his Saturday morning "bake") while I'm working on my bike and casually lecture me on "wasting" my money and time. Yeah, the guy who spends untold amounts of money on weed is lecturing me on my motorcycle project! And I've never said a word to him about the money he spends on his weed. It's his thing, I understand that, but obviously he doesn't.

I've had people on (the other Ninja) forum try to shame me or discount my projects based on the money they cost. These same people almost certainly have things they "waste" money on, but not on their Ninja, so in their little minds they decide that nobody should "waste" money on a Ninja project.

About the idea of doing a full Euro-spec EX-250 transplant. There are problems with that idea. I may have time to mention them later, but right now I've gotta catch a flight.

LOL I spend money on my mybike and the herb...those guy's can surely be pricks at the "other forum" So far in all my considerable 250 searches your F.I. conversion is one of my favs! Too bad he can't share while he lectures you. Damn I bet pilot's pee in cups rather often

Cool - thanks for the injector info. That will come in handy when looking at injectors / pumps / filters.

I think my problem with the money is I have too many things I'm into - home improvement projects, project car, guns, tattoos, cutting trees and firewood, ATV maintenance, etc. Sometimes it's overwhelming when I look at all the crap I've got in the basement and garage, but it's rewarding when you can create and modify things the way you want, maintain your home and vehicles yourself, and when certain skills carry over from one thing to another.

The FI conversion is certainly not a waste, IMHO. It sounds like it runs nicely, is much easier to tune than carbs, and I'm sure you've learned quite a bit in the process of doing it (thanks for sharing, BTW). I just need to find a way to make it a little bit cheaper in order to justify it to myself...

Hope you have a safe flight.

Yeah, between my two flying jobs, Southwest Airlines and the Air National Guard, I pee in cups all the time. In fact, if you hand me a cup you're liable to get a urine sample back. I actually find it a bit offensive/degrading to be tested all the time. I like to fight back just a bit. Every time I get "randomly selected" for a screen I tell the person administering the testing "Hey, you're in luck. I'm in a position to upgrade to you a stool sample!" I never get any takers on the offer, but I think they understand my meaning.

Well, I've got plenty of pictures. Just tell me when you've seen enough!

Since we were discussing parts of the system as I built it, here's a lineup of some of the major pieces:


The fuel pump is a Suzuki LT-R450 Quadracer unit. I was worried about the fuel pump choice because the EX-250 doesn't have a lot of extra electrical power available. I needed a pump big enough for the job, but really easy on the amperage. This pump is great on all counts: very available on Ebay, low electrical draw, easy to mount, plenty of pressure/volume for the job. (Switching to LED lights in the bike's brakelight cluster covered the fuel pump's draw. My voltmeter shows high 12s to mid 13s at idle)


Here's how it looks mounted to the bike. Yeah, the bracket is ugly. It's just a temporary solution. I'm working on a cleaner, better looking setup. Not that it's visible to anyone because it's totally hidden up under the fuel tank's bottom hump.





I stuck with the Suzuki LT-R450 source for the fuel pressure regulator. It mounted up easily in my application. You've got three lines to plumb: high pressure input line from the fuel pump (about 50psi), high pressure output line to the fuel rail (43psi), and low pressure excess return back to the fuel pump input line.


The fuel filter was a bit of a puzzle for me. I eventually settled on a 1992 Honda Accord filter. I realized I needed a filter that had the inlet and outlet on the same end so I could bury it through the bottom of the old airbox floor. I needed it to mount in an out of the way place because I was trying to set the whole system up in a way that would allow me to remove and replace any piece of the system without having to take the rest of it apart. It hangs down just to the right of upper shock mount.

There's lot's of little power draws for things like the injectors, the fast idle valve, the fuel pump, the oxygen sensor and it's controller, the MicroSquirt itself, etc. Every bit of it has to be "key switched" power.

So I installed an ignition key-switched auxilliary power panel. It sits on the left hand side of the bike between the CDI and the coolant reservior.



Here's a picture of the relay that controls the whole thing. It uses the horn circuit to provide trigger power to the relay. It's the one on the left above the fuse box (the one on the right is the fuel pump relay).



Here's a picture of the main fairing (off the bike while the work was being done). This shows the mounting for my clock and the Air/Fuel ratio guage. The Air/Fuel ratio guage gives instantaneous feedback on the bike's performance, letting me know at a glance if my tuning is working out correctly. For example, if I'm cruising with a small throttle opening the proper tune would result in a lean mixture (for fuel efficiency) of about 16 to 1 air/fuel ratio.

Awesome greg.
once your bike is tunned, you'll still have to use th wide band o2 sensor or will you be swapping out to a regular one? I heard if you use the wide band for normal use, it'll burn out fast.

i can attest to that, I have burned through a bosch five wire (the sensor that came with the LC-1) in about 20K miles in my WRX. I replaced the rear stock narrowband lambda with the wideband unit and ran it all the time and it lasted about the 20K above. The new one I will only keep in the exhaust for tuning session and track/autox time.

I keep on learning things about the fuel injection game. I may have successfully "fuel infected" my EX-250, but there's still a lot for me to learn.

i can attest to that, I have burned through a bosch five wire (the sensor that came with the LC-1) in about 20K miles in my WRX.
Your mention of the fact that Wideband sensors don't have a very long lifespan is news to me. However, I do remember reading where guys were tuning their engines on the wideband and then switching to a cheaper narrow band sensor once they had the engine running sweet, but I didn't realize the reason was sensor life.

The weather in Spokane has been crappy for most of December so I haven't been able to work on getting my new fuel injection setup properly tuned. It ran fine in early December when I posted the Youtube videos, everything works correctly, just not tuned to a fine point.

I haven't been able to ride it for much of December due to the weather (and my In-Laws have been in town for over two weeks, just kill me now!). You have to ride it to be able to take datalogs which you then use to tweak the MicroSquirt's tables to a really sharp level of tuning.

Here's hoping I can ride it during January and February. I want it to be "full-up" by springtime.

Why spend money on a dyno when he already has wideband?
