Some of the reasons for the year after year RELIABILITY BSA Motor Cycles sliding; dog-clutches (A) and (B). The illustration shows the gear box of the B.S.A. 3.49 h.p., Two port O.H.V. 4.93, De Luxe 0.H.V., and two port O.H.V. models. Gate Change lever is on left slue of tank. All B.S.A.’s have indestructible clutches. SUMP LUBRICATION This system is designed on lubrication principles, and is provement over the old c-i ng ear of type ...eehanioal oil pump. It cuts out all external oil pipes, which are liable to break or become stopped up, and ensures greater efficiency in the lubrication of the most vital part of the engine—the big end bearing. The bigend bearings of B.S.A. models equipped with sump lubrication receives 250 times as much oil as the big-ends in engines fitted with the ordinary system. Yet the oil consumption is remarkably economical Once the correct setting for the control knob is obtained you need never touch it again. So long as you replenish the sump every few hundred miles the pump will faithfully provide perfect lubrication.

'The design allows a current of air to pass over the springs when the machine is in motion, so that cooling is not affected. The use of this • greatly reduces the accumulation COV€ of dust and stems and w< heads and the ably lessened. •ad grit oi r between alve stems the the tappet is eonsiderthrough louvres cut in its sides, and passes through a lining of silk before, reaching the carburetter. Dust is thus effectively prevented from reaching the engine. The lining is supported and held in position by a coil spring. A light spring-loaded flap valve prevents the silk catching fire in the event of a blow-back. Any reversal of gas travel between the engine and the air cleaner causes the valve to close. The exclusion of dust and grit from the cylinder walls and moving parts of an engine results in greatly reduced wear and longer life. » TANKS. All B.S.A. Tanks, including the 7.7( h.p. de luxe model, are of the saddh type. They are fitted with kneegrips (Except 1.74 h.p. A 29). The 3.49 h.p and 4.93 h.p. two-ptfrt models ar* plated with a top panel in B.S.A All other models are cellulose finished in the usual B.S.A. colours FRONT HUB AND BRAKE ENCLOSED FRONT CHAIN. In the 3.49 h.p. and larger machines the front high-speed chain is enclosed in a two-part case. The illustration shows that fitted to the 4.93 h.p. O.H.V. machines. REMEMBER that there is B.S.A. representatiy Province. Call B.S.A. agent near you. Authorised nearly every town in the Auckland the nearest for a' FREE B.S.A. demonstration. The life of the chain is considerably lengthened by thus keeping it free from dirt and water and lubricating it regularly by the means supplied GcfcATESfiftYfflTELm., J| V biC vcle and motor importers • S FORT STREET, AUCKLAND. m A SNIP ! \ Indian Prince, O.H.V. 3.49 h.p. sports model, electric lights and horn, 3 speed gearbox, handle-bar trolled clutch, bucket seat and twist grip trols. This machine lias been on the road,, but being shop soiled, we are offering it at a big reduction to cj.ear. Original The use of taper rollers for the wheel hearings ensures that heavy loads may be carried over rough roads for prolonged periods with the minimum of wear. All B.S.A. Brakes are internal expanding type. The brake shoes are steel pressings, light and yet sufficiently strong to resist heavy stresses without distortion. The generous width of the linings gives a large contact area, so that a powerful retarding effect is obtained with medium brake shoe pressure. A large range of adjustment Is provided for the shoes. \ cost £BS, reduced £59 10/- CASH, Xo terms can be accepted at this price. /
