Here’s some pics of a Yamaha FZR1000 cylinder head and lower engine case that we did some machine work to. We gave the five valves per cylinder aluminum cylinder head a high performance valve job and surface along with milling .375 thousandths off each end of the head at the request of our customer. The lower engine case needed the threaded oil filter boss machined down flush with the o-ring seal surface to accomodate a different oil filter setup.
