The 4-valve Guzzi has to be one of the most imposing powerplants of all And Jasper Mulder, a marine currently working in Nigeria, was so he chose his 1993 Moto Daytona on the strength of that alone. “After a huge on a modern superbike that my leg in several places, it was time to down a bit,” says

He’s always loved the of Guzzi’s liter-class V-twin, so he the Daytona without even a drive. “After the first ride on the thing, it was obvious the handling and brakes had to be improved. So where it all started.” The bike is a work in progress, but it already has a brutal beauty. Mulder’s goals were to improve the brakes and chassis—and then the

All good stuff, but it sound like Jasper is slowing down one bit.

Moto Guzzi Falcone

His Falcone Compressore, a 500cc Guzzi Nuovo Falcone to a supercharged café racer, came to life.

The inspiration this magnificently engineered was sparked when Leo saw the supercharged Guzzi 250cc factory in the Guzzi museum at Mandello. He had a passion for Guzzi singles, and so the of converting a 500cc Nuovo to a supercharged Guzzi single was Some chatting with enthusiasts stirred up the fire.

A from a local motorcycle thought it possible that a would go fine with a “I doubted this for five but it didn’t stop me from it,” Leo states. Measuring superchargers that he came during trips to Italy no suitable basis, until he found an Eaton blower for a Mini that had the required It was still too long, but a band saw reduced it to the proper length.

simplicity is the driving force this bike. Any sort of without any sort of measured resulted in just poor and a lot of kicking. After some Leo fitted a Lambda sensor gave better feedback on the ratio, and this led to proper (“But that’s about as far as go with electronics…”) This motorcycle is not supposed to be stuffed digital engineering.

Instead, it embodies the spirit of the limits” in the days before the era. This keeps the of the Falcone within the 60s and 70s period, of taking the easy way out. the beautiful SU carburetor—no injection on bike. The SU allows for quick even while Leo’s riding the bike, since in a convenient and accessible position.

The build of the bike has executed in a 70s style, taking from various motorcycles and of that era to create a consistent Leo has fitted MV Agusta 750S brakes, laced with spokes into polished rims. The polyester tank was without a bottom to allow for fitting the plenum.

quite a wizard when it to fabrication—he owns a welding and company. You could say that flows through his veins, and his skills are clearly visible in bike.

After finishing the in 2009, Leo tried different and carburetion settings. “In the beginning was little information on the pressure in the . so a friend kindly lent me a dial which supplied the feedback”. Stationary fills it 7.25 to 8.70psi (0.5—0.6 while 4000rpm gives to 20psi (1.3—1.4 bar). The valve opens at 40psi bar). “It could be more, but first,” says Leo. liters of fuel mixture is I don’t want a backfire and the roof of my garage.”

The air to fuel ratio should be 11:13 for this engine; the sensor comes in handy It gives proper feedback on and makes diagnostics easier. It at a price though; the system is 80 watts, draining the battery, so has to be upgraded. The bike is fitted a Volker Sachse ignition curve), which makes it run

There’s of low-end power, and full is a real joy.” Leo estimates it has 40/45 HP.” Not consistently the Compressore is moody sometimes. you could say, just a lot of Italian machines. The recently cylinder head, with timing from the Volker ignition, gives a more bang lately.
