Rusty Gold 2014 - Part 10

Dirty Donkey update

Super Motor Co almost finished their new custom the Dirty Donkey. Last Sunday Dimitri invited me to look at his latest creation. In March I posted about the Dirty Donkey for the first time but as you can see a lot has changed since then.

I was there when the engine was fired up for the first time. :) We first tried to bump start the engine but something was wrong with the flat slide carb. We found the problem, decided to borrow the kickstarter from Salt Shaker and it came to live with a wild roar. It is loud I an tell you, very load. Check the small video here
It's a mix between a vintage scrambler and trial bike and it's powered by a 140cc engine. This is the second custom coming from Super Motor Company and it share's a lot of design cues from the Salt Shaker. You can see the Dirty Donkey on Eicma later this week.

Dimitri:
"It wasn't all plain sailing when Lenny came to visit me. A plastic cap
inside the carb was mounted upside down. That's why it would not start and
pissed fuel everywhere. On the floor but also inside the exhaust. We've
had to tilt the bike 180 like a rampant horse, or should we say donkey!
And half a litre of fuel poured out.
But the most serious problem was a melted silent block that attaches the
exhaust to the frame. I've used silent blocks before but never a regular
one. The enormous heat generated by the exhaust melted the rubber like a
chewing gum substance. But mounting the exhaust directly to the frame with
a bolt and rubber bushing was no option either. It would peel the paint
off in seconds. On Monday morning I started calling around looking for a
ceramic coated m8 bolt and the lot to stop the heat entering the silent
block. But no success. I could not get one in time. I finally found an
insulated silent block today with a heat resistant gasket inside... thank
god.
On Thursday morning I am off to Milan in the company Beemer touring with
the Donkey in the back. I've had no time to test anything so wish me luck.
The engine runs fine but does not get on full song. Really have to fiddle
with the carb and the jetting. Probably have to go a bit leaner.
let you know about the progress and get back to you with final specs once
the bike is finished and tested..."

Thanks Dimitri and good luck!

Salt Shaker

Just finished these two side panels for the Super Salt Shaker.
On their way to the Eicma right now for 70th International Motorcycle Exhibition.
15th till 18th November in Milan.

This is the first time I painted with pinstripe paint. Not easy, I can tell you that but I like it for a first try :)
The Salt Shaker will be shown during the Eicma show at Officina Mermaid, the Italian distributor of the Super 120’s.

Super “Salt Shaker”

This very nice custom has been popping up every where on the web recently.
It's Build by Dimitri from Super Motor Company. Super Motor Company is a
Dutch Motor Cycle company based in Amsterdam. Here are some extra detail shots of this custom Super 150 and the dyno run print.

At the moment I'm painting the side panels of this Salt Shaker. The painted bike will be send off to Milan (Italy) and will be shown during the Eicma show at Officina Mermaid, the Italian distributor of the Super 120’s.




Here some info about the build:

"Sometimes you start on a bike that along the way gets bigger and bigger 

ending up as a totally overambitious project. We did start such a project 

over a year ago, a small capacity racing bike, that we just could not finish 

due to lack of funds. Carbon fibre this, Chromoly that, 3000
euro here, 2000 euro there, we wanted the lot. Stoner once said to Rossi: 

“Your ambition outweighs your talent”. In our case the ambition outweighed 

the wallet.

Back to square one. What to do when you have a Super Cub frame laying 

around, a tuned and flowed 22 bhp 150cc engine, racing tires, rims and 

other bits and bobs? Turn it into a ‘non’ run of the mill city sled! The 

inspiration ranged from pre war JAP speedway bikes to post
Nazi NSU’s. Ad a touch of Bonneville salt and a sip of Bergringrennen beer..

and there you go…

We started off with chopping up the frame, the fabrication of the ducktail 

and welding a tube between the headstock and the fuel tank. This tube now 

functions a 250 ml reserve fuel tank. Most time was spent on the prep of the frame. Three full days of grinding, sanding and priming. The frame was sent off to the painter, and swinging arm and rims to the powder coater. Beforehand we knew it was going to be a waiting game since we got a really good deal for both the painting 

and the coating. It’s ready when it is ready so to speak.

But still we had lots to do: the nitty-gritty stuff. Brackets, brake cables, clutch cables, throttle cables all the little parts that had to be made to measure. Lots of work for things people will really not notice. Next up was a military spec wiring loom. Never knew how much time you can spend on such a vital part. It’s either right or wrong. No in betweens. In some lost hours we made a custom seat pan out of glass fibre, got some race foam which we shaped with an angle grinder and with some gaffer tape we made a pattern for the leather upholstery. And then off to the 88 year old grandma to stitch the leather pieces together. Grandma loves doing seat upholstery. She‘s done dozens over the years and she is good at it.

When we got all the parts back after a few weeks the assembly was pretty straight forward. Within a day the whole bike was together. The last and most vital part was still missing. The exhaust. And we definitely wanted a JAP style pipe on it. And this had to be made from scratch!

A company called Shipping Tools in Zaandam, basically an Amsterdam suburb, 

quoted 50 Euros for one and 70 for 2 exhausts. Good deal...but let’s wait and see. After many hours of fitting, adjusting and tinkering the exhaust was ready. 

And beautiful it was. We paid 50 for it but the offer for a second one was 

withdrawn. Quite understandably so, because the guy did spend some serious 

hours on it. A second would now cost us 150 euro’s. Which I think is still a 

bargain for a hand made stainless steel exhaust. I strongly recommend them 

if you need some tubing bend or welded in the Amsterdam area. Their TIG 

welding is spot on…

In November the bike will be send off to Milan (Italy) and will be shown during 

 the Eicma show at Officina Mermaid, the Italian distributor of our Super 120’s.

If you want to see it in the flesh and running you might bump into us next 

year at the Bonneville Speedweek. We are planning to do a few runs on the 

salt flats. We might even challenge the class record. You’ll never know…
