Am I asking for trouble?

While I am normally so strict on putting keihins on 4stroke Hondas, I found something funny and wanted to give it a try.
If it works it would be period correct and being a downdraft like this, it would look cool, especially if I could find or make an alloy funnel. But on the other hand, something italian, known to give trouble.... maybe I should think of a keihin back up plan.

S90 trial bike finished

The last parts for the engine rebuild came back, so I could finish the S90 Trial bike for Arie.
He has now started his own blog about the bike, find out everything about the build here:

My contribution exists of an engine overhaul with some custom modifications, bringing it up to 113cc within the original cylinder, custom weighted flywheel for trial use. Custom built cables all round, some rear brake modifications and few other little details.

gearbox work

The SS50 racebike, a project that has been in a corner for a long time, is now getting a new chance.
The rules for 4-strokes have changed, allowing them to be 85cc in the 50cc class, and as my CB50 was sold, I need something new if I want to ride in the 50cc class again.
Well the SS50 racebike had an almost complete 85cc race engine made for it, so that would be a good start.

Just needed some gearbox work, as the first gear was too short for the rest of the custom made close ratio 4-speed gearbox.
It is put together from SS50, S65, Z50 and other parts and now getting a taller first gear consisting of a chaly gear grafted onto a chinese shaft.

seen in this picture, from top to bottom
- Takegawa 5-speed 14/33 first gear
- Custom made chaly / chinese 14/32 first gear
- Cut off chaly 2-speed gearbox shaft
- chinese 11t shaft for bearing type engine casings (of no use in my old SS50 cases)

freshly built SS50 engine

Just finished myself another engine. classic looks on the outside, but with power inside.

looks like a very early 5speed ss50 engine

extra mounting point in front on the cases and no engine numbers

Made this way with modified S65 cases, fitted with 52mm stroker crank, 52mm cylinder making 110cc, with a ported CL70 head, fast camshaft, 2 plate alloy clutch coupled to a modified original Honda 5speed gearbox and many more modifications and rare 60's parts such as the engine covers and breather kit.

CR / RC style levers

After moving to a new workshop I'm aiming to expand my production, now tooling for making complete CR / RC style brake and clutch levers.
I've already made perches, but just now I've tested my prototype home made lever, quickly machined it to work as original, mounted to an original perch and squeezed with all my might....and it stayed intact :D
That makes it possible to remanufacture almost all the parts so I'm not reliant on NOS parts that may or may not be available. Now to work out the last bits before production can begin

Since I've built a new tacho for my 50 this year I got annoyed by the quality of the old prints for the tacho face. So I asked a friend who is good with graphics and has his own company in printing if he could help with new tacho faces, not only the CR110 / CR93 replica, but also an RSC and two different smiths faces, like the ATRC tacho's.
Today I mounted the first test print into an old housing to see what it would look like and how it would fit. Just a few tweaks and then it will be ready for a small production run.

also available will be:
smiths from 1 to 14
RSC from 3 to 15
CR110 CR93 replica 3 to 16

all to fit in original honda 1:7 tacho's as used on most models up to 500cc

another batch

And yet another batch of brand new vintage parts.
Including two of the newest project, a rear backing plate for 110mm Honda hubs, SLS but also in the future I plan on making a 2LS out of it, some preparations for that are already in the mold.
Planning the 2LS for my RSC90, will make the rear hub fit more with the 4LS front CB125RSC hub.

the line-up:
160mm front brake plate, Honda RC styled
110mm rear brake plate, Honda RC styled
CR110 footpegs
CR750 clutch perch
Honda RC styled brake pedal
JRP breather covers
S-monkey oil cooler adaptors
RSC engine cover, meant for a Honda 50, but going towards a 750
