Line 1: Line 1:
The term "Port Timing" Refers to the relationship between the [[port]]s being uncovered by the [[piston]] and the position of the [[flywheel]]. The size and location of the ports in a given cylinder are the largest basic factor determining it's performance. [[Port map]]s provide tuners a way of [[calculating port timing]] of different cylinders by giving them an accurate depiction of the port size and location in the cylinder bore. If the ports are positioned in the cylinder to be opened sooner in the flywheel's rotation it is considered to have an 'advanced' port timing , if it is opened later it is considered to have 'retarded' port timing. This can be altered to affect the performance of a [[piston port]]ed two stroke engine.
