2-STROKE: Cylinder and Head Modification

TBT Racing :  uses the latest in high performance engine modification software for port modeling and design. After pinpointing the optimum design for your engine, each head is precision milled on a CNC lathe for exact tolerances to match the cylinder modifications. This results in maximized combustion efficiency and higher peak power. TBT Technicians clean, de-burr, reshape and texture the transfer ports for crisp throttle response and quick-revving power. Then they shape, smooth and polish the exhaust ports for the widest possible spread of power for race-winning performance.
