It´s alive.........I am happy and a bit scared.......what kind of MiniMonster did I create ?
I fried the secondary coil, replaced that ( and have an extra CDI now on the shelf ) ,
and the engine fired straight up again.
Did a few sprints in the yard and had a mix of "wide grin" and "what the heck" face,
low-end and mid-range will be more than enough for urban traffic
but when that motor gets "on the cam" in high revs it´s OMG time, +20hp is quite a handful.

Slightly too loud for german roads and cops, will baffle until compromise is OK-ish.
I am over the moon and cant´wait for the special re-registration with all mods declared and in the papers,
will be costly but those guys doing it are an almost extinct species and riding legal is worth it.

Hello SupaCool,
I already HAVE a Monkey +12cm swingarm in there, not Over but Kitaco, quite beefy and in a Dax it´s +10cm,
there are longer ones available but then the re(ar)setting of the mudguard is much more work.
I like the "Super Street Bike" look only on 1/4mile SSBs,
on a street Dax the radii of wheel and mudguard should have the same-ish center point.
I am quite pleased if you thought that there was a stock swingarm mounted.
The Monkey version is stronger , and mounted outside of the frame on custom polymer bushings,
much better than the rubber-mount stock arm inside the frame,
stock setup tends to twist once "heavy torque" from big block engine is pulling on the chain.

Well done Benni. Hope there are no hiccups registering it legally. You might defo need to investigate a longer rear swingarm with that much power!
Nice Dax Jay. That's a great buy. Was it like this when you bought it?
Basically yes it had the z50 bottom end aleady, but we went to 88r when the engine needed a new crank case. Plus I sourced the Over exhaust. Nice Dax Jay. That's a great buy. Was it like this when you bought it?
It was 1k in the 2000s
I also have the new Dax 125, I havnt ridden it this year, nuch prefer the tuned older bike

I had forgot you had said this previously. It does look very stock which fits in perfectly! Ace work. I already HAVE a Monkey +12cm swingarm in there, not Over but Kitaco, quite beefy and in a Dax it´s +10cm,

Hello Supacool,
Inspired by your turbo monkey, I'm doing a very similar build, but with a Zongshen 212cc 4 valve (this might be nuts!). Loved your monoshock mod so that's the path I'm following. Can I ask which shock you went for, were there any cheaper options you weighed up, and how much you weigh? I'm 85kg in gear, 95kg when touring.
I'd also love to see an up close photo of Nigel's modified monoshock mount please - may try to emulate it. Did it allow you to use a longer shock?

Regardless of the freezing temps, I went for a dyno session on Monday for basic setup checks.
I slightly de-tuned the engine by fitting a S15 "sissy" cam which takes off about 2-3hp,
but moves power to a much more street-usable charakter, I don´t want a 12.000 rpm screamer.
The video atteched shows the movement of the chain, I knew that there will be slack & movement in the lower part,
but was surprised to see up to 15-20mm movement in the upper part, under full load, at two rpm windows.
Must be something with vibrations of a single without balancer and chassis getting " in tune",
I will try to address that with a 3rd engine mount and a spring-loaded chain-deslacker.
The 175cc TJR Nice had 18,6 at the crank and 15,8 at the wheel, with a good line of power and torque.
https://youtu.be/C_WxEVs_dHo
Mixture is a bit rich, this will get worse once temps hit 15-20° plus, I will have to address that
with different idle jet settings, needle settings, or even trying out different needles but this is a science of it´s own.
But better too rich than too lean, will have to watch oil temp on longer runs.
I winced a bit when the operator kept the throttle open to almost 12.000 but he said :
"This is a Honda, they take that", and so far it did.

Just a slight derail from "Monkey Magic" to "Wave Lunacy" :
It seems there is a small but enthusiastic Drag Racing scene around the "Honda Wave" scooters,
which were supposed to replace the Super Cub in the 90s bit never gained their legendary all-purpose status.
However, the Wave & Nice engines have ignited and inspired some new generations of tuners and aftermarket companies,
the engines are fitting into Monkey/Dax and their clones, my Dax driven by a modified Nice.
In Germany, the "bigger is better" race has led to some modified 212cc ZongShen blocks with 4valve daytona Anima heads,
top of the heap is currently about 240cc and carbureted ~35hp, steetable, electric start.
Some asians have taken this to absuloutely insane levels and SMR Factory Taiwan have CNC machined a block
still fitting into the Wave chassis, which has to be elongated a few inches to fit the CNC machined "Ducati Desmo" style
cylinder and 4valve head taking the displacement to..........1000cc, WOW.
https://www.instagram.com/racemontage29 ... 1A-/?hl=en ( third row from top, middle reel with yellow Wave )
OK , there is some periphericals missing and how will it go ?
Well, Bike Empire Thailand have completed their little drag scooter and took it to the track :
https://www.instagram.com/racemontage29 ... 5VQ/?hl=en ( third row from top, right reel )
Well, 8,99 @ 167 mph is not too shabby, cap doffed to the engineering and riding skills.
Small tires seem to be one of the "Honda Wave racing" rules.
I guess the engine price tag will be as hefty as the performance, and if this well ever be topped ?
€dit : I don´t know how to link the insta stuff directly, sorry.

Good job - it is worth fitting an oil cooler to help keep temps in check? I bet it's great fun!I slightly de-tuned the engine by fitting a S15 "sissy" cam which takes off about 2-3hp,

I will keep an eye on the oil temp gauge in the filler cap when spring comes.
A tiny Takegawa thermostat is on the shelf, will be joined by a small SETRAB cooler if needed.
Also on the shelf : the very rare headstock oil cooler from a CR 450, looks super clean but is difficult to mount and plumb.

Hiya - sorry for the tardy response. I've not checked on this thread in a while. The shock I used was from a pitbike seller. I will follow up with some details as I am on a different PC.

I used a cheap mono shock which I think I pictured earlier and it was very under damped and as I've put on weight in my 40's it was not stiff enough-That's what she said! The current shock is spring preload and dampening adjustable and works well for my 90ish Kg weight. I went to the trouble to ask the sellers about the spring rating. I might have that as well. I will go and check when i get back on my laptop.
Benni - the engine is pretty stout with those numbers! I defo need to get my carb tuned and adjusted properly. This year will be fine tuning the carb so it runs sweet. Currently there's some flufflyniess and stumbling when initially getting on the throttle. So suspect it's the pilot screw or idle that needs a adjustment. Or I need to pull the needle up a notch.
We are already into the 2026 and I've not had any plans for this years updates. There are a couple of reasons. I've not been right since we had to put our dog to sleep just before christmas and not been motivated to do much. The other is I am at risk of redundancy at work so am uncertain if I will be employed in the future. But now as I am writing this, my mind is working on what I want to do next. I will go and see the main man Nigel soon and discuss the next evolution.
I'd like the tank painted as there are some imperfections on the back garden respray. I would defo like new gold bars, perhaps with a little rise on them to raise the bar height, perhaps some fresh cerakote on the brembo caliper and the under sllung exhaust - depending on the cost...
Keep this thread going!
I modified a Monkey part to fit my Dax, to give the frame a little more strengh in the engine mount/swingarm area.
3rd engine mount without welding, adds a connection between footrest mount and brake pedal axle.
I had to cut the CNC alu parts and add some beefy angle steel pieces between the engine plate and pedal clamp,
those two parts will be welded and some tiny gusset plates will be added, then the assembly gets black coating.
