The company won't but maybe an American here will do it on your behalf.....  That is one way around  "they do not ship to OZ".

Bill that is probably possible, but if I knew exactly what model and year, or even better a part number. It would then be easy to either go to Aussie injector specialist or go to the wreckers. It would also benefit the other Aussie & Kiwi members. However thankyou for the suggestion.

Well they are showing the flow rate so maybe one just has to get a bunch of them and measure.  As cars are built to differing markets an american 318i maybe lower flow rate than an Aussie one.... Worst case is it won't work.

In the engine>fuel system there is a thread of one who has done them and likes them ....
I'd link it to you if I could figure out how.

For some reason the #3 vacuum cover was off. I replaced it plus filled the tank with Valero 92 octane and techron. Ran it home at 70 mph and it does seem smoother. It still is slightly hard to start and it surges idle but IT DONT DIE!!!!! I got inspection and insurance today, plates tomorrow and I'm gonna try and take it to work on Saturday. I have another trip out of town and am gonna send injectors for cleaning.

Depends on your definition of "better" and how do you measure better?  Better for some is higher peak power, others is greater milage for a gallon of gasoline, for others it might be something else, who knows.  Like Martin, I've read threads with anecdotal evidence of no difference in power or performance between single-orifice and 4-orifice injectors.  There is evidence they use more gas.

Given that the control of the injectors does not change any change in performance would be nominal to the flow rate. The jetronic controller is pretty basic compared to modern units.

I am concerned that the smaller orifices in the four hole injectors will be easier to block with smaller bits of dirt or fuel deposits.  When I am riding somewhere far from home I want every part of my machine to be as reliable as possible.  I see these four hole injectors as sacrificing a certain amount of reliability for some dubious claims of performance or fuel efficiency.

Is it unusual that the bike starts best with choke just barely closed? I only need to move it just enough to get light  on.

That's not something I'd worry about, todd. I usually run my bike a ¼ mile at ½ choke before I close it. I don't worry about that either.

It would be really good to see back to back tests on a Dyno. And I am still trying to work out if there is any benefit of a 4 hole v 1 hole given that they are not directly injecting into the combustion chamber. All the information that I can find is anecdotal and based on things like it feels better, without any verifying proof. I will continue to look into it but not convinced enough to blow the money on a feeling.

One hole's always been good enough for me. I'd like get back some of my money that was blown on feelings though.

Just remember this is not a choke like a carb.  It is a fuel enrichment sent via the ecu is it not?  Or do I have the method confused with my other fuel injected motorcycles

You aren't done yet, todd. Wait until you've installed clean injectors into a cleaned system to assess what's weird.

This choke just increases the throttle. You could get the same effect by tightening the throttle screw—if you had one—on the handlebar then twisting the throttle grip slightly before starting. It's called a choke because, surprisingly, nobody wanted to coin a new word to confuse buyers crossing over to K-bikes. If it's not shut off, the revs will stay up to provide a surprising and stimulating effect when cornering.

For those helping me, I have these fairing mirrors if anyone wants them. Give me a fair offer and they are yours. Include mounting hardware, mirror glass is good and both blinker lens. Paint is chipped and worn out. Unsure if blinker lights work, never hooked them up.
Thanks!!!!

Well the rear brakes stopped working on the way to get a plate. They do not apply pressure. There is no fluid leaking out and the reservoir is full. Guess I need to pull the master cylinder.

Todd talk about bad luck, that would have really cheezed you off. Hope it's an easy fix, pull the boot back and have a look. You could try a quick temporary fix, take the cylinder apart give it a clean and re bleed, could be a blocked port?
