camshaft lift

Camshaft lift, duration and overlap must not be altered from stock.

In some motorsports there are rules that limit camshaft lift; therefore, provoking this type of exploitation.

Thus the valves open and close earlier or later; however, the camshaft lift and duration cannot be altered with a cam-phasing system.

For greater midrange torque, the CB900F's camshaft lift is lower, and compression is slightly lowered.

Camshaft lift and duration were eased back and the torque curve reshaped to a street-oriented peak of 5,200 rpm.

Valve and port sizes and angles, camshaft lift, compression ratio and carburetion were frequently amended from model to model, depending upon whether power or torque was being emphasised.

Starting with the 2002 model year, the LS6 engine output was increased to 405 hp (302 kW) due to a larger CFM air intake, stiffer valve springs, lighter sodium filled valves and more aggressive camshaft lift and timing.
