Dr. Jeffrey Purk, the racing dentist, and Jeff Chen were the ones to watch in CCS and USGPRU action Sunday at Road America.

Dark Horse Racing’s Chen took a runaway win the USGPRU 125cc Grand Prix race, held in conjunction with the CCS regional event. Nicky Cummings, age 15, grabbed the holeshot off the line on a damp, but drying track. Chen passed Cummings on lap two, and the pair swapped the lead several times. On lap two, Cummings, riding on full Dunlop rain tires, out-drove Chen up the hill out of turn five to re-take the lead but then lowsided in turn six. From that point Chen, riding a Dunlop slick-equipped Honda RS125, pulled away to win by 17 seconds. Dhracing.com’s Robert Rawlins came back from early race troubles, passed 14-year-old Taylor Knapp on lap five, and closed slightly but came well short of Chen, his teammate. Third-generation-racer Knapp ran second, after his teammate Cummings fell, but had to settle for third on his Ray C’s/Cummings Harley-Davidson-backed Honda.

Later, with the track almost completely dry but extremely cold, Purk left Dunlop rain tires on his DDS Racing Suzuki GSX-R750 to take wins in the Heavyweight Superbike and Speedscreen Unlimited Grand Prix races. In the Unlimited GP, Purk came from behind to pass early leader Geoff May and went on to win by 6.1 seconds. After missing the warm-up lap, Shawn Conrad started the race with cold DOT-labeled Dunlops on his Suzuki GSX-R750 but charged forward to pass May and finish second. May held on to third on his Embry Racing GSX-R1000.

With his dry-pattern Dunlops pre-warmed, Conrad was more prepared for the later Heavyweight Supersport race, but Purk chose to start the Suzuki contingency race with the same set of Dunlop rain tires. Conrad and Purk overtook quick starter Montez Stewart and dueled to the end. Running the fastest lap since before the rain began (2:28.65), Conrad was able to beat Purk to the checkered flag by two seconds and take the Heavyweight Supersport win. Stewart finished third on another Suzuki 750.
