C O RR ECTIO N : The Vet ' Jun ior cl a s s results from the opening round of the CMCIDodge Truck Go lden State Nationals, held J a n ua ry 5-7 in Castaic, California, were incorrect. There were two divisions, w ith Kenny Kopecky (S uz ) the winner of Division One, followed by the riders listed. The fi nis h ing order of Division Two was: 1. Steven Lawlek (Ya m ); 2. Jeff Haas (Hon); 3. Randy Skinner (S uz ); 4 . Garrie Turcotte (Ho n ); 5. ~ o h n Clifford (Yam). Riders co m peti n g in the Camel Su percross Series will be ab le to take advan tage of two or three specia l . semi na rs this season th a t will help them deal with th e media. Accordi ng to Bob Moore, Camel Supercross public relations m a nager, the program will be im p lemented in early Ma rch before the Da ytona Supercross.

We rely o n batter ies to start our engines , yet seldom g ive th em a second thought u ntil th e time co mes w he n we p ress th e sta rter button a nd n ot h in g ha p pens. Dead batteries are something we a ll h ave to face ' soon er or later. Batteri es slo wly d ischa rge th ro u ghou t their lives, whe ther th ey're used or not - especia lly on motorcycles. U n like a ca r battery which is con sta n tl y recharged by the car's power fu l alt ernator , a mo torcycl e 's a lterna tor gen erates on ly en o u g h p ower to maintain th e battery 's existing ch arge. And with repeated .. starts a nd constant d ischarge, that · cha rge slowly beco mes wea ker. Age isn ' t th e on ly thing that drai ns a ba ttery: tem perat u re a lso speeds wear, and vibration causes material with in the battery to break down. Although batter ies do eventuall y wear out, their lives can be prolo nged for troubl e-free operatio n with the proper care a nd cha rgi ng. . T he rea son a battery wears out is attributable to its co m positio n. The type o f battery used in m ot orcyles and cars is know n as a lead-acid .stora ge battery, a lso referred to as a wet -cell storage battery. Wi th in the pl astic housing of a 12-volt battery are six cells co nsistin g of p lates, separators a nd an elec tro lyte so lu tio n . Ea ch cell produces 2. 1 volts . Positivel y-ch arged plates a re co m posed o f a lead di oxid e p aste on a lea d gri d , wh ile negativel y-ch arged p la tes are mad e of a m etallic sponge lead p a ste on a lead g rid. T he electrolyte is a water solution co nta in in g 36% su lfuric acid b y weight. Any wat er th at is safe for drinking, except m in eral wa ters , is gene ra lly safe to use in a ba ttery. . Electricity is forme d within th e battery due to a che m ical react ion. Wh en an elec tri ca l co n nec tion is made - such as when the starter button is p ressed or ligh t switch turned o n - both th e lead dioxide o n th e positive plates and sponge lead on th e negative p lates combine with the sulfuric acid in the wa ter. T he elec tr olyte so lution becomes diluted as th e pl a tes tak e up th e excess su lfa te. T h is che m ica l reacti on cre a tes a flow o f el ect ron s th rou gh the electr ical co n nections . It al so crea tes hydrogen a nd oxygen gas which accumulates a bove th e water in eac h cell an d is rel ea sed in to th e a tmosp he re through th e battery 's vent tube. Some gas does rem ain in th e cells, h owever , a nd this h igh ly fla mm abl e gas ca n ex p lo de if exp osed to sparks, flame or even a lighted cigare tte. _ When th is che mical reaction takes place for lon g periods of time, both sets of p ositive a nd negative pl a tes are coated with th e lead su lfate an d n o longer have opposi te charges. There is n o lo nger a reaction so th e electrons stop flowing, m ean in g th e battery is d isch arged. A battery wo u ldn 't last very lon g if th is reacti on co nstantly occurred. T hat's wh ere the a lte rnator co mes into p lay. T he alternator creates a charge to reverse th e che mical rea ction a nd force electricity. ba ck in to th e battery. Lead dioxide reforms o n positive p lates, spongy meta llic lead returns to n ega tive plates and wa ter turns bac k into su ifuri c acid. Road vibra tions also a ffect th e cha rged p lates. Asa battery ages. the -Iead p astes start to fall off th e plates and co llect a t the bo tto m of the battery. Eventually, the residue will bu ild u p a nd short out th e pla tes. There are two wa ys to det erm ine th e condition of your battery: One is by using a voltmeter to measure th e ba ttery's voltage level. According to Schauer, a ba ttery charger m anu factu rer, th is is best done a fter th e battery has sat unused overnigh t. The second way is by using a h ydromet er to measure' the specific gravity o f the electrolyt e solu tion. In a low-battery conditi on, th e electrolyte will be more like water a nd wi ll give a specific gravity reading of I. When th ere is more than 0.05 0 d iffer ence in th e specific gravity between th e cells of a fully-charged battery, it shou ld be rep lace d: Si nce a low battery's electrolyte solution is more like wat er , it will freeze q u icker. The su lfuric acid ac ts as an an tifreeze, lowering th e freezing p oint of the wa ter. A froze n ba tte ry shou ld be avoided since it co u ld crack the cas ing. Next week , we' ll co ntinue ou r d iscussion o f ba tteri es by co veri ng battery maintenan ce a n d recharging tech niques.
