Kawaski GPz900r Appreciation Group member James F. has graciously agreed to share his knowledge of installing FI into his Gpz900r.

James, the way I’ve set up this page is just how I would probably like to read it. You might even convince me that it’s a better upgrade than Mikuni RS36’s!

I’ve added links to the FB photos I have found and given each a number. If you send through a title and a description I will fill in the blanks. Of course if you have anyy other photos or videos just send them through as well, and add a nice overall image of the bike if you have one.

The same applies to the content below the images – these are simply the steps that I imagine you went through. Again add as much detail as you wish and even add additional steps or change the title where appropriate.

For this stuff there is never such a thing as too much detail, but it’s a balance.

One of the common issues I have with forums is the lack of detail –  it always annoys me when someone posts a detailed question and folks reply with monosyllabic answers or simply don’t read nor understand the original question.  Hence why I’m putting this site together.  But I suggest you only give the overall view with key insights to discovered problems (that can catch folks out) – for this stuff a key skillset is being able to figure out some stuff yourself.

And since it’s my site so I don’t care what you write – I just appreciate you taking the time!

Send it all through via email to

Cheers Adrian

Info on what these are from?


First Fire Up

First fire up!


Info on your bike and why you choose to go down this path rather than, say, flat side carbs!

Required Additional Parts
List of bits needs – with photos hopefully
Again a list of things (existing and new) that need modification like tank etc.
Skill-set & Special Tools
Whatever you think is needed for the job
The Installation Process
The run down of steps – hopefully including insights into what worked or didn’t and anything else.

Detail is entirely up to you, however the more you can put in the LESS others will ask silly questions, and if they do you can easily just point them back here and call it a RTFM (Read The F….g Manual) problem.

Tune-up and Settings
Pretty straight-forward
The End Result
Basically what you think of it!

About the Site

My family loves older vehicles, the newest one we own is 2003!  But I am acutely aware of the ownership complexities especially:

  1. they often need more 'hands-on' mechanical work &;
  2. there often isn't any local expertise from the service centres;
  3. there is often no new parts available from the manufacturer;
  4. parts often have to be sourced 2nd-hand or from overseas.

So we often end up doing a lot of the research & work ourselves and this information gets stored either locally with the bike or online forums - although finding the useful parts in these forums isn't always simple.

The original goal of the site was simply somewhere for me to record service work & contacts on my GPz900r so that my kids (the one that likes bikes anyway!) could easily access it - it doesn't concern me if it was publicly available.

I then realised that with this online structure in place I could also offer it to other owners, and the site could potentially expand to record other owners experiences and expertise , meaning we can learn from others but also pass on this knowledge to subsequent owners of these wonderful motorcycles.

At least Covid-19 has given me plenty of spare time to pursue my passion for the motorcycle!
