This is part 2 of Tomo Racing’s Suzuki GSXR-1300 Hayabusa motor rebuild. In this video, master engine builder and multi-time national champion drag racer and crew chief Tommy Bolton shows us how he preps a motor for his “Tombo Touch” rebuild. You can see his attention to detail as he preps the pistons, gaps the rings, and has the camshafts prepared to his demanding specifications. He also explains the head porting, polishing and flow benching process. In a later video he will show how the pistons and cylinder block is installed, the valves installed and timed, and the motor completed and test run.
