Hank Scott Racing Services
Innovative products combined with a complete machine shop and expert engine building services for Yamaha racing engines is the main business at HSR. We take extra care in preparing your engine using only the best parts available. HSR is constantly improving the "weak links" of the Yamaha FJ1100/1200 engine to provide the most dependable combinations. The FJ/XJ engine is very durable, however when it is used to power an 1100+ lb race car/driver the extra loads, excessive heat, and sustained high RPM can cause engine failure. We build our engines to withstand these abuses with proven assembly techniques and bolt-on products to insure engine longevity. We can provide our customers with the newest updated information in our monthly newsletter.
