ZX10 injectors

[Supercharger_Mark]

Has anybody got 4 standard ZX10 early model injectors laying around collecting dust I can buy?
Any model will do, I want to adapt and try them in the Z1 to see if it gets rid of the accelerator enrichment problem I'm having.
Cheers
Mark.

I prefer it as it is; I can just about keep up with you.

By the way, don't you hate it when you get excited that there is a reply with maybe some injectors and it's just me being a dick?

[Supercharger_Mark]

Thanks Si. I was so overwhelmed buy the response I brought some off Ebay

[Gix11]

Is it fixed yet?

[Supercharger_Mark]

Still waiting

[ozzy1100]

Did you end up using the micro squirt unit mark?

[Gix11]

What about now?

[Supercharger_Mark]

No not yet

Still waiting for the pig tails so I can finish the wiring.

Who can guess what I used to make the fuel rail?

Yes Ozzy, Just changed the injectors, got rid of the 2nd tank and plumbed the return straight to the main tank.

[Gix11]

You should be a plumber mate!

....oh, and is it finished yet?

[ozzy1100]

Oh snap silver solder and copper so much win......
Whole thing is so much win

[ozzy1100]

Do you find much diffrence with the injection over carbs ?

[Gix11]

...what about now?

[Supercharger_Mark]

Not yet Si.
The injection feels a lot smoother, can't tell if it goes any harder, hard to tell, feels about the same at full throttle.

[ozzy1100]

Nice and don't worry that can always be reminded lol
I have always wanted to have a go at the micro squirt looks a top unit

[slingy88]

Ha ha Luv that fuel rail Mark. Bloody tops ;-)

[evad]

Come on Mark, surely there can't be anything wrong with those 30 year old injectors!!!! Lol
Is the problem sorted out ?

[Gix11]

Yea, Dave's got a point. ........Is it finished yet? :)

[Supercharger_Mark]

Yes Yes Yes, its not easy being a tight arse you know, its quite a challenge.

No not finished yet Si but on Wednesday, I did make a make shift harness for the injectors (till I get the real thing) and went for a ride, it feels pretty good, very smooth at low speed, I need to get up in the hills and play with the accelerator enrichment to see if it has solved the problem I had, however I have created a new problem which I should have foreseen, when I brake heavily with less than a 3/4 tank full, the fuel rushes forward and exposes the fuel outlet and bingo, no fuel pressure, shit, so other than baffles in the tank, anyone got any suggestions?

[ozzy1100]

Surge tank?

[slingy88]

Longer hose between tank and pump?I probably have about a metre of 1/2" bore rubberpipe in a loop under the tank to the pump and it will run the tank virtually dry without any running issues.

[Gix11]

Is that somehow contained? I wouldn't like to be riding it if that pipe got broken for any reason if not.

Not as bad as it sounds

Sorry old pic but you get the idea. Also means i can take the tank off and on to get to plugs etc without removing the pipes as well as sit the tank on a stall along side the bike and still run the motor so actually very usefull.
And, although i didnt think about it at the time its volume probably works like a surge tank, as i have never had fuel level related issues.

And, i like riding it, shit pipes and all.

[slingy88]

Ok, another couple of ideas.

What about a Clunk in the tank? Model planes and cars use them. Its like a very flexible pipe fitted to the inside of the fuel tap/Fitting with a wieghted hose barb pickup on the end so it always sits on the bottom of the tank. The weight then follows the G forces the fuel does, so is always in the fuel.

Or, i am sure i have read about a sponge type product, which is quite open structure, which can be cut to the rough shape of a tank, then just crushed up and fed in through the filler, where it springs back to its origional size inside the tank and completely eliminates any fuel movement. Like i say, it was very course in its "holyness" so didnt actually take up much volume or act like a sponge and hold fuel , just eccentually created a million little baffles. Or, i could just be dreaming lol.

Or just dont brake into corners, that will solve the problem easy as lol

I use fuel tan k foam in the race bike, you can get it for the dirt bikes. It is a open structure foam that acts like a baffle. it comes in cubes and you just stuff it into the tank until it is full of foam. works great so far, I usually run the tank to empty or it stutters then add about 3-4 litres for a race/run so it is on empty most of the time and I have no trouble for with it coughing in the race.

Yes! So I wasn't dreaming lol

A picture is worth a thousand words.
I love the KISS system.
Works well till I switch to reserve and I can live with that, and so easy to adjust the reserve amount.

[Supercharger_Mark]

What!!! speechless???

[ozzy1100]

If it works it works, results are all that matter......
Nice and simple

[slingy88]

KISS? Enlighten please.
Or is this just what you do with the Z when no one's looking :-*
So just a solid pipe inside the tank, bent to reach the bottom middle of the tank from the fuel tap.
Nice and simple. I like it.
Have you just chosen this method because you get to play with more copper pipe and fancy yourself as a plumber now lol

By the way what size are the ZX10 injectors? Low or high impedance?
What are the issues with the AE?
If there is anything I can do to help just let me know.

Cheers jack

[Supercharger_Mark]

It seems to work fine so far, I'm sure it would be a different matter on the track but its only an old clunker and I've thrown enough money at it, so it can get fucked, that's all its getting.

Slingy, KISS = Keep It Simple Stupid. and yes, pipe inside the tank but fuel pipe not copper.
I don't know what the 08 ZX10R injectors flow, Ben (yes that Ben) suggested using them because they had a better spread/atomisation with about 8 spray holes I think, they are also less than half the physical size of the others, which was good (gave me more room) their High impedance which meant I could get rid of a lot of wiring because the old ones were low with resisters.
the AE worked well at low speed, eg traffic, highway speed, but up in the revs 6k+ when you blip the throttle e.g. coming down gears, just a big bog, not what you want coming into a 35k bend at speed, a few lock ups.
I haven't tested it in the hills yet but don't think it fixed the problem, the angle into the bodies are too steep compared to late models, so I think the spray is still hitting the floor and turning to liquid, I'm going to roughen up the ports to see if that helps.
I'm open for suggestions. (as long as it doesn't cost too much)

[Gix11]

Who cares about tubes in the fuel tank; LOOK AT THOSE DRAWINGS! Top shelf mate.

[slingy88]

Pretty sure this will still be setting issues.
Like, at what revs do you stop the AE? I think like above about half revs Ae isn't even needed as there is enough intake velocity to match the ve table.
The AE is to add the extra fuel needed when sudden intake pressure changes occur which is really in the first half of the rev range.
What about fuel cut on overrun? Have yof got that enabled and if so what settings?
I really don't think it's gonna be an injector issue. Talk to evad and find out what his Ae settings are to compare. Or ask on the MuS forum.
Anyway, great work, your nearly there

[Supercharger_Mark]

Yes Si, its a hidden talent of mine, colour and everything.
Shit Slingy, its too cold to go down to the shed tonight, I'll check the settings tomorrow after work.
Cheers.

[slingy88]

Shit Slingy, its too cold to go down to the shed tonight, Ya big girl lol

[Supercharger_Mark]

Slingy, What you say makes perfect sense, I've been under the impression it was a lean bog but I don't remember looking at the
AF gauge to see, too busy trying to stay upright.
Fuel cut on over run is disabled.
The AE down-scaling with RPM was.
Full AE below 8500rpm and Zero above 9500rpm.
So I changed it to 4000 and 5000.
I'll see what difference it makes on the weekend.

[slingy88]

Yep that sounds more like it. As you know, I don't have too much experience with AE but from what I have read about it, your new settings sound better. Might be worth throwing the lappy on as well and dataloggoing the events too.

[slingy88]

Any updates on this Mark?
