The New Four-cylindered F.N.
It will be very easily understood that such a go-ahead firm as the Fabrique Nationale would not let the grass grow under their feet. It is not surprising, therefore, that their 1906 model has undergone many improvements. These improvements, which we describe below, will be carried out on any 1906 machines at an inclusive price of £5. In the first place the silencer has been re-designed, and is now, we understand, really worthy of the name. The carburetter has also been considerably improved, and is particularly regular in its action. The throttle lever, when pushed forward to open the throttle, also opens the air inlet at the same time. Baffle plates are fitted at the top of the crank case, which effectually protect the points of the plug from being fouled by the oil.
The flywheel and coupling to the transmission-shaft are now encased, and are efficiently protected from mud and wet. Two toolbags are supplied with the machine, which are fitted on either side of the tank. On both of these, compartments are fitted outside for the purpose of carrying oil and paraffin cans.
The manner in which the exhaust valves are lifted is convenient and ingenious. There is a long brake lever fitted in the usual position, which, when pressed down, raises the exhaust valves in a particularly easy manner. A small catch can be slipped into position, so that the valves shall remain permanently lifted.
Lubricating oil pumps are now carried in a slanting and forward position, so that they can be conveniently reached by the rider.
The direction in which it is intended for the oil to flow is regulated by turning the handle of the plunger. Two brakes are fitted to the back wheel, one being operated by the same lever as raises the exhaust valve. (This lever, by the way, does not bring the brake into action until the valves are completely lifted.) The other is a back-pedalling brake, which can be put in and out of action at will without the rider dismounting, by means of a small lever fitted underneath the saddle. This brake is of the internal expanding type. The 2¾ h.p. F.N. remains practically the same as it was last year.
