Within the cylinder block lies the basis for power in any internal combustion engine.
Special care is needed and proper machinery required to effectively work on a cylinder block.
On our project bike this area needed particular care since the total engine meltdown had turned a good part of the old piston metal to dust. If there is one area where there is no tolerance for inexactitude or sloppy assembly, it is the cylinder block. Rohm Performance Machine wanted to make sure the detonation specter didn't rear its ugly head again. So, the project motor was treated to an innovative series of modifications designed to lower compression and prolong engine life. Before doing this work, however, the block itself demanded attention to bring it back into an acceptable condition.
