You were right. That's a compressor !
The guy lives in a very familiar place. I use to hang-out in Kelowna in the summer. It's western Canada's wine country. Great weather, great scenery, and plenty of roads to open-up !
INFOS :
"Roger Goldammer is no
stranger to the world of wild custom bikes. The front of his shop in
Kelowna, British Columbia is crammed full with lathes, milling machines
and a huge CNC machine. Roger takes his equipment and his work very
seriously. He does not follow trends in custom bike building by
building the expected "Chopper" nor is he drawn in to follow the pack
delving into the popular "Old School" variety that has become all the
rage lately.
Together with his long time friend and mentor,
master machinist Bert Kuckelkorn, Roger looks for ways to improve and
innovate the mechanical design and function of the motorcycle power
plant. As a recent winner of the Canadian Championship of Custom Bike
Building and a two-time winner of the World Championships, Rogers bikes
are on the cutting edge of technology. " I like to challenge myself "
says Roger. So, for his entry in this year's competition he pulled out
all the stops.
Not
being content to rest on his laurels as the two time World Champ nor
his Biker Build Off victory against Matt Hotch at the Bonneville Salt
Flats riding a bike he built utilizing a racing go-cart engine, Roger
went back to the drawing board to improve on his single cylinder with
turbo rear design that he made famous in his TROUBLE bike that won him
top World Championship honors the last time he competed.
The
NORTORIOUS, at first look, brings to mind the classic lines of the very
significant Norton Manx Café Racer but that's where the similarities
end. The engine is a 2006 H-D hybrid single cylinder Roger built from
the ground up. The 965CC engine features a lower end consisting of
Merch cases rotated back 15degrees and balanced internals. The heads
are custom from Engenuity and the pistons from Ross and Jims lifters
were utilized. The cam is custom designed and manufactured by Roger.
The rear head is used on the front cylinder, allowing the induction
system to be positioned above the head and cylinder with the angle cut
back 15-degrees . The pushrod tubes are also angled to accommodate this
change . In place of the rear cylinder, a Rotrex Supercharger that
spins at 120,000 RPM was installed. The half a v twin produces 83 rear
wheel horse power at 6400 rpm.
The
fuel injection uses a 54mm Zippers utilized throttle body and a special
Thunder Heart ECM in a closed loop configuration and an extreamly high
volume single injector. Using the Thunder Heart ECM and a Dobec module,
Roger developed a fuel pump mapping program to provide correct air /
fuel ratios, while running up to 20-pounds of boost to compensate for
the superchargers flow. Many days and late nights were devoted to
getting this set up to work like a charm. The oil system features a
modified S&S oil pump and two distinct oil tanks, both cleverly
hidden from view, one for engine and the other for supercharger oil.
The
bikes transmission started off as a 2006 Baker six- speed unit which
Roger modified by shortening main shaft as well as the Prime/Rivera
clutch pack and belt drive, all narrowed from 3 inches down to 2. It's
a foot shifter with rear sets and has a 24-tooth tranny sprocket
shuttling power to the bikes 49- tooth wheel sprocket.
The frame
is another in house Goldammer Cycle Works creation. It's a chromolly
"Featherbed" style raked 29.5-degrees and de-stretched 3 inches. The
front end is a WP type cut back 1 1/2-inches for superior handling.
The
wheels and brake set up are deceiving. At first glance, they appear to
be stock Norton drum set ups, only larger, while in fact the drum hubs
and custom milled covers hide an ingenious 4-piston disc set up both
front and rear. Many days of hand milling went into this clever
deception and the rear rim is put together for the 18-inch x 6-inch
tire by fabricating the rim from two different Kosman rims.
The
body and fenders on the Nortorious are a true work of art. Roger hand
hammered the aluminum skins with such precision as to show absolutely
no sign of weld work. This is pretty amazing considering that the only
paintwork on the bike is the lettering and a clear coat over the raw
material. You can see the masters touch in the workmanship in the fuel
tank that includes the Buell internal fuel pump and regulator. The bars
are clip-on style sitting atop Goldammer Cycle Works triple trees.
The
Speedometer and gauges are VDO's set like those on a vintage jet
fighter. The design of the headlight also acts as a wind deflector and
just for fun, Roger used the lens and bezel from a vintage Volkswagen
Beetle. The taillights are incorporated in the rear of the bikes frame
and utilize LED lights. The brake light is also an LED set up hidden in
the rear of the seat rail. There is not one visible wire or line on the
bike. Roger cleverly hid all the hydraulic lines and wires inside the
frame tubes giving a fine clean look to the bike.
This shy and
unassuming builder is a genuine craftsman. A close first hand look of
the Nortorious lets you know why Roger Goldammer is the two winner of
the World Championship of Custom Bike Building and the current Canadian
champ. Taking the basic lines of a classic race bike and adding his
engineering genius and fabrication talent we would not be surprise to
see him walk away with a third world class championship"

, this is an atmospheric and not supercharged engine. And this was a German team (suzuki-Fuchs) not a french one.:albino:
