We do not currently know of any synonyms for four-stroking.
The noun four-stroking is defined as:
A type of abnormal operation of a two-stroke internal combustion engine where the cylinder only fires every second cycle (like a four-stroke engine does). This occurs when the exhaust scavenging and inlet charging leaves a mixture in the cylinder which does not ignite, but needs a second scavenge/charge to produce an adequate mix.
