The motor I was building for the SS racer had a chinese copy of a CD90 clutch on it, for a racebike a bit to smooth I thought. So when I heard that a friend had a dry clutch laying around, I jumped at the chance. Thanx Eugen. Had some issues fitting it, because Daytona uses an M6 bolt that threads into the main shaft, but luckaly the Takegawa main shaft was hollow so I could fit a threaded bushing in there.
Starting to look nice, now working on the cylinderhead, big fins, big valves, ported, now some final checks and to figure out which camshaft to use and valve spring tension.
The cheap Chinese cilinderhead I bought at a swapmeat as an experiment now fits my SS50 motor. It needed some machining for it to fit, but it was possible to addapt it.
Just put it on to see how this big finned head would look, prety race-like. The manifold and carb were just a quick try to see what would be easy and possible, but I don't like the looks of this, the carb is too strait. I will probably use the 26mm carb of my motorcycle.
This weekend I didn't do that much, I cleaned a chinese 125cc cilinderhead that will be adapted for the 85cc racebike and found out that it will need a lót of adapting to fit an old honda motor..... the chinese moved the top two cilinder studs upwards. Didn't feel like tackeling that just yet, so I chose an easier project; the top yoke. as seen before with handlebar mountings and so on, but now modified for a racebike:
I've been collecting front fork parts to upgrade two of my bikes. I want my SS50 motorcycle to have thicker front forks, as it struggles with the original 25mm forks while at the same time I would like to upgrade the SS50 race project with stiffer yokes and better internals. By now I've found pretty much everything, so I've started work on it.
These yokes will have the handlebarmounts removed to look like MT125R yokes, the clamp will be more stable then the bolted type. Forktubes will be replaced by MT5 tubes that will be shortened, thes also have the big plugs on top that match with the clamped yoke. The internals will be made as a copy of an MT125R forkleg, which actually has some sort of damper. Sadly loose parts are not available, but I have a forkleg on loan to copy from.
As the forks were out of the frame, this was also the right time to weld on a fairing stay:
that was some slight progress on this project, I've also started on the front fender, but that is on hold again, as I had some parts for another project
Yes I've gone over to the kitakkiewakkie-craft side.... I've traded a spare CL70 head, which are quite rare over here, against a takegawa superhead with worn valves and some more little issues.
Today my dad was looking around for something to do, so I gave him the cilinderhead to go and play with :P Guides were reamed from 5mm tot 5,5, to fit standard S90 valves, seats were cut, head was glassbeadblasted and the valvelift was checked with the cam that came with it. This all looked good and it will become the cilinderhead for my SS50 racer project. Now just to decide on a gearbox and clutch.
I've heard that a German friend might have a spare clutch, he races an SS50 engined kreidler, but I sadly can't find any contact information. If you know this guy, or if you are him, could you give me an E-mail?

My tank is being painted, thanx dad. We had a big can of red, so that's what color the tank is going to be. Decided to remove the old emblem mountings as they were pretty mangled, probably will look better with a classic set of honda wing stickers and some silver stripes running along the length, just like the old RC tanks.
I'm liking the way this looks, might just put it back on my SS50Z moped, to make it look more like the way it used to, long ago:
Same tank by the way, one or two crashes earlier...
My dad has been working on one of his Beemers, that will need its tank coated...this got me thinking about an old SS50zk1 tank I had laying around. When coated it would be usable again, if something could be done about the mangled filler opening. And so this project began:
the original opening has been cut out and replaced with an original Honda flip-up cap that was cut out of a CB-motorcycle gas tank. I never really liked the looks of an SS50z tank, but this really makes it a lot better. I might even use this tank for my race project, otherwise it will be a spare, or for sale.
With the SS50 race project being for sale, the chance exists I could actually sell it to someone and I didn't really want to loose the Takegawa clutch that was on that motor. So I decided to switch it over to my 110cc engine.
Now the motor is rebuilt...again... with a 5speed gearbox, Takegawa clutch updated to 4 plates with some leftover china junk.
But that meant I had to start building a new engine for the racebike. SS50Z cases, 5speed gearbox (and a spare 4speed close ratio) clutch moved to the gearbox input shaft by using chinese parts combined with a little bit of Kitaco, 85cc piston (allowed by the SAM) on a 12v crankshaft. I have some plans for the head, but I'm not that far yet. yesterday I did start on something for the breather, made it out of a CL72 filler neck that will get a bung welded on the rear to attach a hose.
It looks way high now, but imagine an upswept exhaust running just underneath that.
The old rearsets that came of my SS50 motorcycle are not wasted, they have been recycled on the SS50 racer project. Makes it more of a complete bike real quickly.
Anyone interested in a SAM racebike project? I have so much projects I might never finish this one, so it is for sale.
As if I didn't have enough projects, I started a new one, just to use some of the parts I have gathered over the years for the cancelled CR110 replica project.
It will be an 85cc racer for the SAM 50cc class (4strokes are allowed to have 85cc)
first time outside, the lengtened swingarm was just ready, made from a CL90 swingarm, now with needlebearings. Long wheelbase like the Van Veen kreidlers back in those days. I plan on keeping it pretty simple, mostly using parts I have. Also, the project is for sale, would somebody want to buy it and finish it themselves. That would give me more time for other projects.
The plan: build a mechanical tacho and tach-drive onto an SS50 engine. terms: do not use kitaco or takegawa bolt on stuff.
I started with a tach drive from a CB175, turned something on the lathe and took the teeth off of an old camshaft sprocket, this should be soldered together with silver and mounted to the camshaft. should look like this when mounted: The housing was cut down to remove unnecessary material and to create a hole for the bolt to go through that will hold everything onto the cylinderhead. A brass plug will be put in there with threads to accept the bolt. One problem, on a CB175 this is on the right side of the camshaft, on the SS50 it will be on the left, so the tachocable will be turning the wrong way.
On the back of the Yamaha 600 guage unit (that I took the tach from for the RSC90) was an angle drive that I could use to reverse the rotation...
Some PVC tubing, a CB50 tach and one Yamaha drive later: Testrun if it all works...NO?... I looked at the angle drive the wrong way, so it doesn't actually reverse the rotation. I will have to make something else to fit onto the modified CB175 drive and use this tacho on another bike when it is finished. Will be painted black, alloy ring to be turned on the lathe and a piece of plexiglass to close it all up, after I've made a new face for it, probably upto 14000 RPM or a bit higher.
