I had a set made at a local machine shop, which specialises in
gears, but I'm in Holland.Cost nearly € 1000,-. Problem is, that
1 gear is part of the primary
axle. My first gear goes up to 75-80 KM/H.

I suppose if you're building a racer, expense goes with the
territory....
Have you read about the Henk de Vries bike?

Seems to have spent as much on lightening as on tuning.
IIRC, all the gears were alloy, with tooth rings shrunk on, and
the cases were drilled almost through.

Hi; banquo. Its proving a litte bit more expensive than what I
thought so I guess some of my other toys will have to go . as
for alloy gears I don't know if I would feel confident using
them I'm hoping for about 50 bhp at rear wheel lol. But one
step at a time. Cheers rodders.

Looks like my memory failed me anyway; it was the primary gears
that were modified:
"Tuning article from Aad van der Valk
Minus de Vries is an experienced tuner of Nuovo Falcones. He was
the owner of a Motoportbikeshop in Wormer which is now run by
his sons because Minus is 65+ already. Some years ago he saw a
Nuovo Falcone and some ideas were born. He went to Italy and
bought a couple of old, rusty not running NF�s for a few
hundred pounds.
The photo, was made by me on the 25 anniversary of the MGCN and
at that time in 1997 I did not know then that should met Minus a
little later. It looks like a NF but I can assure you that
perhaps two or three screws are still original besides the
hardware on the OUTSIDE of the engine. Minus was willing to tell
so much about the machines (there were three of them .) that it
is a pleasure to just listen to this impassioned man.
He showed us, for example, the weight of the machine. He put a
scale under the front wheel and under the rear wheel and
together the result was ... 120 kg! This is nearly 100 kg less
than a standard NF.
At that time he had just reworked the machine and was a little
surprised himself too.
After some time he revealed the secrets of his ability�s.
Everything but then he meant everything had been close-looped to
reduce the weight. He showed me a crank-case in which the inside
had been securely drilled out and all walls thinned in order to
lose weight; primary gears with aluminium centers and the
original gear teeth as a circle shrink-fitted. A reworked
crankshaft, special piston, own made and designed camshafts,
light valves and springs, rockers and push-rods, reworked head
and a tuned 36mm carburettor
.
He told me that in the veteran races some 3-cylinder Yamahas
must go to the limit to pass him after a few rounds.
I think the racing talent of Minus, he races the machines
himself together with his brother Henk, is quite a contribution
to this but never the less it shows the incredible capacity of
the one-sparker (oh, sorry these NF�s have two
sparkplugs). He does not know the number of horsepower but when
he says that the machines do 200+km . I believe him rightaway.
In order to keep the special look a hand made aluminium,
chromed, flywheel is still fitted."
