(DRAGBIKE!) and probably IOBA." It was also rumored that Spencer bought Frank Iacono's number-tworanked Pro Stock 1983 Camaro, too! When Spencer goes racing, he gets serious! Other first-round action included Gero defeating Kirkwood with an 8.788/145.63 to 8.965/146.57. Kirkwood's bike lost fire on the line and Gero had his clutch heat up while waiting. Gero said, "I didn't want to win on a solo, I am here to race. The hot clutch did concern me, though." Mason put away Walker, who missed a shift, with an 8.701/150.75 to a 9.262/141.06. Mason was changing the gearing between rounds and said, "We tried soemthing new, but we're going back to what we know works." Carpenter shut down Hayes with a 8.702/149.25 to a 8.994/144.69 in the final race of the first elimination round. The first rac~ in _the ~~mi::!inaJ. round pilled Vance against Gero. Before the race Gero said, "This round is gonna be real LOugh." He was right - Vance put him on the trai ler with an 8.631/ 152.28, which was also good for the top speed of the event. The last semi-final round between Carpenter and Mason was a rerun of tbe last time these riders met in the semi-finals at the recent NMRA Western Nationals. This time Carpenter cut the best light of the event, with a .462-second reaction time, butin doing so, the bike left the line so hard the left grip got yanked out of his hand, causing him LO shut off to regain control of his nearly sideways machine before gelling back on the gas. By then, Mason, the 40-year-old-grandfather, was long gone, turning a 8.631/151.77 to Carpenter's losing 9.286/149.00. Mason said before the race, "At this point, this round is more important to me than the final (because of the point ballle). It might be one of the most improtant races I've been in." The final brought together the same racers as in the Western Nationals - Vance vs. Mason. It was an ihtense selling with some interesting confrontations. The latest, but unproven, Kawasaki equipment against rhe oldest in the field, but definitely proven, Kawasaki. A young rider with nine championships under his -belt against an old veteran trying to 'earn points for his first N MRA title. Mason's rival in the points chase, - Carpenter, was rooting for Vance. "Come on Terry Vance! Don't make my mistake so bad!" Carpenter pleaded. Carpenter got his wish. Vance barely outgated Mason, .469 to .503, and went on to take the win with a 8.569/151.51 LO a 8.576 and identical mile-per-hour figure. After the win, ""Vance's crew was ecstatic, with Hines leaping nearly three feet in the air. After Vance thanked his sponsors, including Accel, Wiseco, Klotz, Tsubaki, Bell, NGK, and his tuner Bryon Hines, he said, "I gated him but I hit the bUllon for second early and the engine bogged, but caught back up. At he finish, his front wheel pulled up LO my crankshaft, but that was it. I , 'knew I had him! This win was real 'important to us, we want everyone LO .., know we can make high-performance equipment for all makes." Vance ,I won his 1982 Championship on a , Suzuki, the opening 1983 round on a Honda and now has a win on a Kawasaki . .. , Mason was disappointed but optimistically determined. He said, "It ~ was close! Now we can concentrate on Atco; we'll be real competitive at AlCO!"
