Hello all,

I still have old original injectors on my 86 K 100 engine. It runs satisfactory but I started to think about new injectors.
When tipped Bosch code 0280150210 I got these Shun something injectors, set for 57 dollars and ordered.

A lot of gear now is manufactured in China and the quality is improving. I am currently running a Chinese fuel pump, rear master cylinder and GPS. All are performing fine, the only problem encountered was with the power supply for the GPS which failed. I replaced it with a spare as I could not get an answer from the supplier after emailing him 3 times. However I did order another part from China which did not work, and it was replaced immediately no questions asked. I was told the fuel pumps were crap and it would fail virtually straight out of the box. It is still going strong over 12 months later and it only cost $37.00 AU. I have the OEM pump in the tail in case of failure.

On the injectors they look to be a new company, and the injectors look to be the four hole type. There are alternate views on 4 hole injectors and there is no posted verified performance tests showing any benefit of the 4 hole type.  A mates son who works with injectors said that because of the way they are positioned there would be no benefit. A lot of the seat of pants reports stating that after fitting I felt a definite improvement would be the same if you cleaned your stock injectors. Cleaned and flow checked my a 150,000 K injectors and felt a definite improvement.The one down side of the four hole injectors is that the holes are a lot smaller and therefore more prone to blocking. Until the one hole versus the four hole is actually dyno tested  objectively without bias and the results printed I'll stick to the stock ones. You can however buy a set and do a report, somebody has to be the first.  Boldly go where no Bricker has gone before.

Regards Martin.

For what it's worth I have a set of 4 hole injectors bought brand new and put them in the K100RT. Improved running BUT I figured ok nice clean ones against old dirty ones. The old ones were cleaned and put back. No noticeable change noted in performance but I ran both options long enough to see a measureable increase in fuel consumption with the 4 hole injectors as against the single hole originals.

At some point soon the K1100LT will get the injectors put in while I get those ones cleaned.

Why you don't order them from Tills, as I did for K1100?

Does anyone have any experience of ordering from Tills and the performance of the injectors?

Hi Edmund

I have ordered from Tills and no problem delivering to Dublin, no experience of injectors from them.

I ordered and installed reconditioned injectors on my K1100RS, same like the guy who installed them for me and who is the best BMW speicalist in all of ex-Yugoslavia. He installed them on his K1200LT and on several other bikes - no complaints:

https://www.tills.de/product-42.html

Quote:

"You will get 4 pcs. original injectors, reconditioned and matched.
Your install the valves in the bike and ...
IMPORTANT:
After installation you will send back the box with your used injectors and the tools within a week, or so. 

Advantage: job done in one got, no downtime for the bike.
Your old injectors are refurbished by us and recycled.

Result, Bike (in this regard) will most likely be better than new because BMW hasn't matched nozzles the nozzles to our specs. at the factory.
Spray pattern and throughput are as the developers would then have liked it in the production.
No tuning, but maintenance and optimization.
Note:

O-rings are new, there are some in addition in the box to cover for the possible event of damage during installation.
Please make sure to order the correct type: 

4 Valve Engines 
K100RS-4V
K1100 xx
K1200 xx"
