We are now offering our seats installed in Hayabusa cylinder heads as an option with other services we perform.
Bronze dissipates heat much quicker than steel which allows the valves to run cooler. Another benefit is that bronze does not beat the valve faces up like steel seats do. This is especially beneficial with titanium valves.
Available for stock size and oversize.

Valve job extra.
