Ok i got the numbers off mine, reads 0280150705.  Think i will mail those numbers to the guy in the USA who asked for them, see what he has to say...  Jeremy

From what I've worked out, that's about as close to the original 0280150210 as you'll get.
The 0280150705 was made for the BMW 4 cyl 1.0, 1.1 & 1.2 litre car engine.

AFAIK BMW never have made any car engine with so small capacity......... Question

My Guess is that the 0280150705 is for the K1, K100RS16V, K1100 and early K1200 models.........which all using the same injector BMW # 13 64 1 461 523.

And WandererK1 have allready stated this........I would guess he owns a K1.

Quite right. Should've noticed. My bad Embarassed
In which case WandererK1 has the correct injector for his K1

I can confirm that a 1991 K100RS 16V has bosch 0280150705 Injectors, 
and a 1985 K100 has 0280150210 Injectors.

Hi all,

I was looking into this type, they appear a lot more common in the uk to get hold off.

http://www.ebay.co.uk/itm/111562934414
Description:
Fuel injector removed from a Freelander, will also fit MG's and Rover's with 1.8 engine (K-series).
Please check your part number.
Part number for this injector is 0280155885

Any reason why I should not give e these a punt? 154cc and 14.5ohms.

Cheers

Dunc

The flow rate is near enough BUT that one is an EV6 injector and won't fit. You need an EV1. There are plenty of threads on the forum about injectors you just need to use the 'Google Forum' search box at the top on the Portal or Forum tabs.

Here's a link with info comparing some alternatives.
http://www.k100-forum.com/t9046-1-hole-vs-4-hole-injectors

Why do you need new injectors? Unless they're totally stuffed your best option is to get them cleaned and new kit.

Once you've had a read come back and have a converstaion about it.

Cheers

EDIT: I just checked and they're actually very nearly the same length (0.2mm shorter). Being an EV6 I think the connector could be different. But at £15 I think there may be some better alteratives

I wouldn't use the four hole type. I bought a set and unless you want to slow your bike down and have a crappy, idle these are not the injecetors to use. This is from very recent experience,  like a  month ago.

You could start by looking here, send your old in and get refurbished units sent back. I've not used these services and believe the guys over on Flyingbrick.de. do.

I've put the 4 hole injectors from ebay seller Osidetiger on several of my Ks, both 2V and 4V. (He grinds the last three digits of the part number off so you can't see them so I don't know what the Bosch part number is. They are green though.)

To be honest, these have never made a noticeable improvement that registers on the highly unreliable "butt dyno" nor have I noticed any improvement in mileage.  They seem to work about the same as clean factory FIs as far as I can tell.

I would love to see a real dyno comparison on these to see if they actually do make a difference.  The guys on Jeep forums are really into "upgrading" to these 4 hole injectors but I've never found anywhere where any of them actuallly did a real dyno comparison.

In THEORY, getting a better misted mixture helps but the only thing I'd really believe is multiple controlled real dyno comparisons...

And if speed/torque/mileage is what matters to you then you shouldn't be riding a brick.  Just get a faster bike.

For reconditioning, I second the  recommendation for Mr. Injector.  I once sent him the worst injectors I could find (totally clogged, very rusty) as a test and he got them unclogged, sanded and repainted them and they looked almost new when I got them back, all for his normal price and with usual quick turnaround.

Totally agree.

Grinding the numbers off is very suspect. If they had green tops I'd say they were the #415 which have a different flow rate (but about the closest 4 hole match for a K2V).

I've also searched hi and lo and not found any empirical dyno evidence supporting 4 hole injectors as an upgrade for the K2V. Not saying they don't work... just not necessary, and possibly problematic. Some owners have installed variable FPRs to accommodate 4 hole injectors but not seen any fuel consumption stats. That's probably the simplest comparative test you could do to determine any improvement in performance but no one's put that up.

The metal bodied EV1 injectors were designed to last 400,000km or more. They just need looking after. A regular clean with new o-rings and filter every couple of years, use a quality fuel and most important, keep the water out of your tank. So replacing the fuel cap gasket is possibly one of the best preventative maintenance jobs you can do.

I am quite happy with the single pintle injectors and have never found reason enough to change or seen any sound testing of them so I am staying with the OEM.

Thought I would add to the confusion here.   

So after browsing through a Bosch Engine Management Components manual dated 2003/4 I found the following info regarding fitment of fuel injectors:

K100   (09/83 - 12/89) uses 0 280 150 210  (LE-Jetronic [LE-2])
          (09/89 -   7/90) uses 0 280 150 716  (Mono-Motronic [MA 2.1])
          (08/90 - 12/92) uses 0 280 150 705
K1100 (01/92 - 12-99) uses 0 280 150 705  (Mono-Motronic [MA 2.1]) 

K1200
LT       (01/99 - 06/03) uses 0 280 150 793  (Mono-Motronic [MA 2.4])
RS      (10/96 - 06/03) uses 0 280 150 705 
 
The K75 is not listed but BMWOA lists the 0 280 150 210 for them and the BMW part number 13 64 1 460 450 from RealOEM and EME support this. 

The only BMW cars that I can find that use any of these injectors are some models for the 320/325/525 series from 1986 to 1990 but only for the 0 280 150 716.  Browsing through the other common Aussie models of the same vintage, they show different numbers so no source of cheap spares from the car yards here. 

And the upper and lower O rings are  0 280 210 752.  These appear to be common across the auto industry but there are a few exceptions. 

The L-Jetronic system appears to be from the late 70's and the LE-Jetronic system from the early 80's and LE-2 specifically for motorcycles.

I would assume from the above that the 16 valve K100s and K1 use the 0 280 150 705.

A lot of info here thanks, I did clean them a few years ago with a 9v battery syringe and some carb cleaner which worked well and I noticed a difference however feel like it's lacking in ompf again which started to make me ponder about injectors all over again. As there is no evidence one way or the other Ion the 4 hole ill likely splash out and get them professional cleaned. On a similar topic, I change out my fuel filter for a new one every year or so however I have never cleaned or replace the filter gauze in the pump does anyone know what service interval is on this and what you actually have to do? Replace or clean? Is it a hassle to get out? Cheers Dunc.

Not sure if that filter is specificaly mentioned in the service schedule but it should be part of the 20000 mile major service or every year. Just lift the fuel pump and check for dirt and damage as they do split along the edges of the gauze as they age.

I religiously monitor my fuel consumption as this is directly related to power output. Last year mine shot up and was varying between 6.5 and 8.0 l/100km. Also developed an annoying engine stall issue. After much help from the forum, found it to be exhaust valve clearances. My fuel consumption came down immediately to a respectable 5.5 l/100km with a noticeable improvement in performance.
Worth checking your valve clearance if you haven't already. easy to check. harder to adjust.

So whats the go with getting injectors cleaned? I just swapped mine over with a new set I picked up cheap on ebay a few years back and just stuck in the cupboard for "later". The old ones were working ok, but are really grotty. Im thinking of getting them cleaned and putting them in the spares bin for later on - much later.

The bike runs MUCH better now. New injectors, replaced a split intake connector, 12 rivet output shaft, rear main seal, new clutch plate, cleaned starter clutch etc. Took it for its first little run yesterday since reassembly. Nice and smooth, like it should be.

Phil, it sounds like it will get you to Urana and back OK.

Yep, should be no worries at all. I dont think the sidecar will be on it though. Not enough time.
