A system, comprising:
- a first camshaft and second camshaft on opposite sides of an activation lever;
- the first camshaft comprising a plurality of cams;
- and
- the second camshaft comprising a plurality of radially misaligned cams, wherein each cam corresponds to an individual activation lever of a single cylinder of an engine;
