Garage sale

I've collected too much stuff for a lot of projects, also some stuff gets replaced, so I have to clean up a little bit.
There is an ad on the dutch 4stroke moped board, but why not but it on the blog too.
Pictures can be found here of everything that is for sale, parts for many different types like C110, CB50, SS50, SL90....
Help me get rid of some of my old stuff so I can build more cool stuff and put it on the blog.
See something you like, give me an e-mail, adress can be found on the right, just under the list of parts I'm still looking for, maybe we can trade.

front brake anchor

Today's work, well a bit of it.
The front brake anchor made from aircraft grade aluminium with a custom bolt to hold it to the brakeplate with M8 12mm castle nut

anybody have an extra front brake arm, early cast steel type?

wheels and tires

The big rim, spokes and tires changout trick is just about done.
The wheels off my C110 streetbike have been laced up to 17" rims again, alloy morad, just untill I can find original DID rims. And the hubs for the C110 racer came in from belgium and after some beadblasting and pollishing, have been laced up to the old 18" rims that came out of the other bike.



Now it's really starting to look like something, with wheels and tires in the correct dimensions. Still need a front brake arm, some bearings and then its on to make a fender and so on.

Aluminium casting

My newest project, aluminium casting.
Because all the cool parts I want on my bikes were made from sandcast alloy back in the days, and now are not, or seldom for sale anymore.
Today was the first attempt to create a casting and it turned out pretty well, if I do say so myself.
Still have some work to do in the form making department, but this first result makes me want to do more.

Form ready for casting, what do you think it will be:


Just poored:


just pulled the object from the sand:


And machined to fit a (somewhat modified) SS50 ignition cover:


It is a bit higher then standard, but that is to be able to mount a 12v crankshaft. And because I made a simple form for a first casting attempt.
Now to refine the process and make a few more covers before I start doing something else, like rearsets, cilinderhead covers and brakeplates.

reduced steering lock

Made some simple alloy brackets to reduce the steering lock, now the clip-ons can be set a bit narrower.


full lock now:

Might just increase the lock, but for now this works to set the clip-ons and not have them hit the tank.

front forks mounted

This is pretty much al the ready to go parts I can bolt on now, next will be some swapping of rims, hubs and spokes, so both C110's can get their wheels built.
And sending out some cylinders to be bored out to 60cc's so I can rebuild the engines.

start building

just started putting some parts on
Found some parts to put together a set of rear shocks with NOS top covers and used chrome ones that are still okay, with stiffer springs on the inside. Hub was supplied by a friend, brakeplate and sprocket carrier I still had.


disregard the OHC engine casings, they are just weight to keep it from flipping backwards and chipping the paint.

Bottom yoke, lower legs and chain guard freshly painted

the Black parts are for my dad's BMW sidecar.

and a set of clip-ons made in CR110/RSC style

now also painted.

Tomorrow when the paint is dry, I can really start getting it together.

Anyone who could help me get a set of rear tank cushions?

painted frame

As of today, I have a red C110.
Thanks dad for painting it.
As seen in the picture it was painted outside, so there is a fly or two in there, but then this is an old-school racebike, this is the way they did it back then. Maybe someday if I were to restore it, it could be painted again, but for now it is more the case that this one is saved from the scrapheap.

Keihin CR29 vs CR31

I compared my new CR31 to the CR29 I was running on my S90.
They both seem to be made in the same casting, so lucky for me, I won't have to go looking for another intake rubber that will fit, I can use the type I have and just order some extra.
Here are some pics of the carbs side by side:
(the 29 is the "dirty" one)



funny how they both have the tickler on the same side, but the cables on opposite sides, probably for some specific purpose.

Keihin CR31's

just arrived from Germany today:
a couple of brand new Keihin CR31's



I already had the resin velocity stack, but I put it in the picture anyway, because I took it out to see if it would fit these carbs. Also very odd is the velocity stack with flange to fit an air filter, never seen one of those before.
Tomorrow I will compare to my CR29.
