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.

brake and clutch levers

I changed the brake and clutch levers to Original stuff.

the old ones (not even Honda, but they have the cool ribbed levers and no mirror mounts):

(old pic, back then still with alloy top plate)

the new ones, original Honda as used on the racebikes with the springs and big adjusters:

Okay, they have mirror mounts, but according to my CR110 parts list, there wasn't even a different part number for the ones without mounts.

Made the cables with original NOS grey cables, thin 6mm with special endcaps made to fit the adjusters that are made for 7mm cables. Thinner cables save weight :P and it just looks better on a small displacement bike.
After this I started getting all the pieces together for the rear brake cable, will probably finish it tomorrow.

Footpegs

Decided on using the replica CR110 brake and shift lever, but the pegs that go with it, are just too wide and would cost me too much ground clearance. Therefor I was looking for some footpegs with a classic look, not the CNC knurled modern stuff. For now I've decided on a set of cast alloy pillion pegs from any modern Honda, but turned on the lathe to remove the hinge part.
I know the method too turn them looks bit odd, but it actually worked pretty well.


Okay, they aren't RSC replicas, but it looks a lot more classic then all the CNC milled stuff out there

brake cable ends

The RSC90 will receive a CR110 brake pedal, originally the cable attaches to it by means of a pin that goes thru the pedal and the end of the brake cable which is a flat piece of steel with a hole in it, as can be seen in the picture of this original CR110:

This is not a standard available cable part, nor is there a similar cable which could be used as a donor.
Therefore today I went to play on the lathe and created a few:

Still needs some finishing and I want to experiment in making them thinner, but then they will also go to the zinc plater. When they come back, I can finish the new rear brake cable.

RSC90 is on the lift again

The RSC is on the lift again, this will be the winter that some modifications will be made.
I've started on the foot pegs, they are going up for ground clearance. The original CYB pegs were just to low and will be moved to a CB72 project that some day will be built for street use. In the picture can be seen a new bracket made to fit the CB72 alloy plates, temporarily mounted the CR110 brake pedal and then built the brake cable stay and stopper screw fitment.



just needs some grinding to finish it off and then it can go to the zinc-plater.

other planned modifications:
- build a new front fender
- replace rear hub with original S90 part (CD50 until now)
- fix 4speed gearbox and make it close ratio
- fit 122cc kit
and if possible, fit fairing, build new tank, paint.......and so on
