Angus you might want to replace the stud with a longer one. I can see thread exposed in the nut and you don't have a Nyloc nut or a spring washer fitted. Please look into this for safety sake, would not like to see the shock come of at any speed.

It has been a while.
Summer time and other bikes to ride so project time has been minimal.
Funny thing, I've spent a fare few days fine tuning the K100's running.
I could not for the life of me get a smooth rev range off idle, it felt very much like a manifold leak, but I had fitted all new manifolds.
When I modified my crank breather connected to a new position on the airbox, I had forgotten to plug off the old connector ( now at the front of the bike ).
Any unmetered air into the airbox that bypasses the Mass Air Flow sensor will wreak havoc no matter how small it is.
So I plugged up the hole and wow....... bike runs, idles, throttles on beautifully.


I also purchased a set of rearsets from a guy from DIXER PARTS.
A great product hand made and half the price of other places.
Whole kit including postage was only $400 NZD !!!!
You can choose to use new or second hand foot pegs, master cylinder etc, and the sets come with all the bits, he even threw in a brand new hydraulic pressure brake light switch.
Took me 15 minutes to get the gear changer on and adjusted, shifts beautifully and the footpeg is 300mm PCD from original footpeg hole.

Purchased another licence plate mount kit.
This one had a better fitment and mounting for a stop light.
I also purchased 2x led plate marker lights ( required in NZ for warrant of fitness )
Wiring was very straight forward.
I also peeled back the end wires from the original foot brake on/off switch and will reuse with the hydraulic sensor switch.


For plugging up the air boxes original crank breather connector, I used a 22mm cap plug from a pocketbike front fork. Glued it on, fitted tight and seated perfectly.
I have ordered from cafe4racer.eu
MARULABS MAGIC BOX BEP 3.0
This will make wiring up an aftermarket speedo very simple and maintain the original speedo pickup and neutral light selector etc.
http://cafe4racer.eu/en/universal-accesories-for-speedometers/296-marulabs-bep-3.html

This box uses your original bikes instrument wire loom, just plug it in.
No cutting, no soldering, it really is the best money spent. No more crying over the speed pickup not working or no neutral light. This box does it all for you.
No need for an expensive speedo cluster, this box will turn that $40 Chinese speedo into a dream come true.

Hi Angus,
Good to see your mods and I was pleased to see NZ still,allows some latitude.I was under the impression rear sets,forward sets were not allowed per se.
I am rebuilding a classic bike with similar mods already existing and were used on the road in the past.I am about to contact the authority involved with blessing these things...Looking forward to classic vehicle rates and it's learner status.
Have you posted a picture of the Left hand side of your bike yet,so we can get an impression of how extreme your appendage is?

There is no latitude.
Rebuild laws for changing rider position and any component that may effect handling are harsh.
Left hand side you can see the air flow sensor on first couple thread pages.
I still need to fabricate a bracket for it.
Bike is running really well.
Currently I am wiring up the rear of the bike and waiting for the Muralabs magic box for my aftermarket speedo wire up.
I am now looking for a stainless brake hose set.
Sadly I am off to the UK in April for three years, so the bike will not get finished.
I have however purchased another cafe racer in London so I can attend the Brighton Burnup 2017
