How do you mount a big vintage carburetor to an SS50?
Step one; buy a big monkey manifold.
Step two; cut it up, weld it back together and turn it on the lathe to fit an original Honda carb boot.
Step three; mount it and add CB750 carb modified to take a normal throttle cable.
Oh, step four; tidy it up, but I still have to do that to the whole 120cc motor.
Everything will be glassbeadblasted to match.
And now just keeping my fingers crossed that I can get this carb to work. My dad has used them before on 125cc motors, so luckily I can peek at those for the jetting.
My SS50M motorcycle needed some new front fork, the Original shortened 25mm forks were just not strong enough for the heavy abuse with a 100+ cc motor and a stoppie producing front brake.
So now some leftovers from the Race project, a set of 27mm forks with CY50 lowers, and for now the front fender of my RSC90 although that is rubbing against the tire.
When working on the forks, I discovered a leak in the CD50 fuel tank, so that was swapped for my old SS50Zk1 tank with modified flip up filler and a racing seat in matching colours, RC style.
tank and seat combo is for sale or trade, if anyone is interested.
As I am gathering spares to restore my C110, I was realizing that a lot of stuff will be left over at the end of the restoration. Tank, engine, forks....
So when I heard that a friend should have an extra frame laying around, I contacted him to make a trade. And so started this project.
It will be a C110 race bike with mostly period correct original racing parts
For now a quick mockup with the CR110 forks and the wheels taken out of the SS50 race-project which will be cancelled for now (leftovers for sale)
Had a problem with my SS50 not running well, but it wasn't consistent, mainly in the higher revs but not always and not with a particular throttle position.
Till at some point, I was looking down at the motor again, while riding, I figured out that it was my leg in front of the carburetor disturbing the airflow....
Solution: take of the cheap crappy long velocity stack, and make a nice shorter one, so I get more clearance to my leg.
turned from the top of some old gas bottle
no more ugly rubber ring holding the screen, but a nice internal "filter" to keep out bugs and rocks.
The tyres on my moped needed changing, they were pretty well worn and probably 8 years old or more.
I decided to go for the classic look, and ordered a Duro front tyre with the idea that this couldn't be all bad, as Honda used them themselves. The rear is a heidenau, but that actually has less grip then the 8 year old Conti, oh well, it is just a moped.
While busy, I swapped the fenders for chrome ones, they go better with this model tank (that i still need to find sidepanels for) the front is a NOS Original one, the rear is a replica that has been on this bike earlier.
Last weekend I had the RSC90 out to play again.
My dad and I entered in a 3-hours event on saturday evening with our co-rider John, this time on his Egli CB750
picture thanx to chalopy
A real experience to ride a real Egli, but the bike isn't built for small twisty industrial-park circuits.
I had a look at pictures of the track before and thought it might just be nice for the RSC90, even with it's horrible gearbox ratio's.
So I took it out of the corner where it has stood for a year or two, dusted it off and took it with me.
Ralph came to have a Look also and took some really nice pictures.
even an action shot
I had a really nice time with this bike again, dispite the horrible gearbox and lack of ground clearance.
I rode the 2 heats without muffler (for the first time)
And the bike sounded great, just like small displacement Honda's from back in the days should sound.
again, thanx to Ralph for the movie and putting it on youtube and his own blog
even I, who rode the bike wearing ear plugs, can't get enough of this sound, so I don't want to keep it from you followers.
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.
Just one quick picture I took of my own SS50 as it stands now
(cooling off on the shoulder of the A2 after a slight case of overheating)
My little Honda was slightly out of place between all the big bikes, but people seemed to love the little thing.
Okay, I admit, it is possible to go lower, but as a daily driver, this is pretty low. I need to take care with the bigger speedbumps and I suspect some garages will be a problem. With slight bumps I can hear my mudflaps scraping.
I just felt like fitting my new wheels, and As I was cleaning the old ones for pictures, I threw a bucket of water over the Golf.
