The AMA-mandated engine teardown following the 750cc Supersport race at Mid-Ohio has worked to the advantage of roadracingworld.com's Chris Ulrich, who finished second at Mid-Ohio.
The teardown revealed that the valves in the engine of Ulrich's bike had started to become somewhat tulip-shaped and were not sealing well, due to excessive racing miles on the engine.
Ulrich's engine was rebuilt with new valves by Shane Clarke and Billy Wiese on Sunday at Mid-Ohio and should be faster at Brainerd this weekend.
Ulrich had originally not planned on having his engine rebuilt until after the AMA National at Brainerd, a track known for its very high speeds.
