'. Flat drag-style handlebars,' chron'!ed tach and speedometer, a cluster of warning lights built into t!:le headlight shell, and kneeguards on the head. Kawasaki's new E,liminator is styled after drag racers; the engine package is based on the Ninja 900.' 1985 KAWASAKI ELIMINATOR LOS ANGELES, CA, DEC. 7 Kawasaki has introduced the Eliininator, a new performance cruiser styled, according to Kawasaki spokesmen, after custom machines seen at street drags across the country. Powered by a slightly-modified 908cc Ninja engine, the Eliminator is designed to look like a drag racer and better addresses 32 real-world riding than sport or semichopper styled'machines, Kawasaki says. , "The majority of motorcycle riding in this country 'is done in the real. world of stop-and-go city traHic, freeways and interstate highways," said Kawasaki Motors Corp. Director of Communcations Mike Vaughan at a press conference held atthe Los Angeles Convention Center. "And the best way of coping with that type of riding situation is with a solid,long-wheelbase motorcycle with an almost neutral seating positionall elements built into the Eliminator," Vaughn said. ''This is a bike . you can ride through rush hour traffic or the Los Angeles freeway system, across the Great Plains or from coastto-coast without feeling like you've just competed in the world endurance championship." The new Kawasaki will be marketed only in the United States and Canada and built exclusively at the Kawasaki production facility in Lincoln, Nebraska, The Eliminator is expected to be in Kawasaki dealer showrooms by F.ebruary and o££ered at a suggested retail price of $4,499. The Eliminator engine is virtually the same as the Ninja inline-four, but with several important diHerences, including smaller carburetors, new cam profiles, ommission of lhe dynamic balancer shaft in favor of rubber engine moul1ls. elimination of the oil cooler, a larger radiator. and a new exhaust system. The Ninja's top-end rush has beef! traded for extra low and mid-range power. Peak torque matches the Ninja, butthe Eliminator is substantially stronger up to 8,000 rpm. Maximum horsepower is down compared to the Ninja, but the Eliminator is substantially stronger up to 8,000 rpm. Four 32mm Keihin CV carburetors with semi-flat slides replac~ the Ninja's 34mm carbs. Tbe slide design 'improves fuel atomi41tion, and throttle response. A new airbox has the same capacity as the Ninja's (6.2 liters). The choke control is on the left handgrip. Valve sizes are the same as useain the Ninja (29mm intake, 24.7mm exhaust), but valve timing has changed significantly. The Ninja's intake valves open 45° BTDC and closed 65° ABDC; its exhausts open 65° BBDC and closed 45" ATDC, measured to and from Omm lift. Intake and exhaust valve lift is9.3mm., The Eliminator's intake valves open 37.5° BTDC and close 57.5° ABDC; Its exhausts open 57.5° BBDC and close 37.5° ATDC. Intake and exhaust valve lift is 8.3mm. As with the Ninja, the lightweight hollow camshafts spin in five cast-in bearings. Each cam lobe actuates two valves through a forked cam follower, and valve adjusters are the screw-andlocknut type. The aluminum cam cover is sealed with a reusable rubber gas~el. For increased durability, the valve spring retainers are anew alloy with equal strength but significantly more elasticity. The included valve angle remains a narrow 34.9° (intake 18.5" and ex" haust 16.4° from vertical), yielding shorter ports for increased breathing eHiciency, compact chambers for increased combustion efficiency, and decreases in engine size and weight. The cam drive is the same as the Ninja's, with a single 7.94mm-pitch ink-plate chain driven from the left end of the crank. Like the Ninja's, the Eliminator's cylinders have pressed-in cast-iron liners; 10 cylinder studs are used. The base gasket is stamped steel, the head gasket laminated steel. Bore and stroke are unchanged at 72.5 x 55mm and redline remains at 10,500 rpm. As with the Ninja, pistons are cast aluminum with an II: I compression ratio. Spark plugs are centrally located in each combustion chamber. The biggest change is the elimination of the Ninja's gear-driven balancer, which isn'.t needed in 'the rubbermounted Eliminator engine. Coun.terweightchanges to balance the new [) ywheeJ eHect were not needed. Theoil pan has been modiued due to reduced ground clearance, and there's a special dam to isolate the primary gear and clutch [rom sump oil for increased mechanical efficiency. Oil capacity is down 0.3 qt. to 3.9 qt. . As with the Ninja, the one-piece crank turns in five plain bearings. Lightweight two-piece rods are forged from a steel alloy, The primary gear takes the place of the inboard counterweight for cylinder four, and the gear teeth are polished to reduce lash and mechanical loss. The maintenance-free electronic ignition, featuring an electronic advance, is on the left end of the crank. Ignition timing is unchanged. Except for the elimination of the oil cooler loop, the lubrication system is identical to the Ninja's, The pump is turned by a clutch-driven shaft. Oil is drawn through the pri(Tlary crankqlse filter to the pump, then passed through the filter element to the crank, gearbox, valves, etc., and returns.lO lhesump. To help prevent leakage (maximum oil pressure remains 71.1 psi), oil passes to the head via external lines. To compensate for theelimination 'of the oil cooler and reduced airflow due to the 18-inch front wheel and tire, a larger radiator (width and height9.25 x 13.78 in. vs. Ninja's 12.8 ·x 7.78 in.) has been fitted with an airflow-increasing dam, increasing coolingcapacity more than 20%. The new radiator wei'ghs 3.2 Ibs. vs. Ninja's 2.54 lbs. Like the Ninja, the Eliminator has
