Crankshaft Assy

For full performance, the engine relies on the piston fitting to precise tolerances, no little end movement between conrod and piston and of course piston rings sealing correctly upon the cylinder bore. Equally important is that the big-end and crankshaft main bearings are showing zero play.
If all the above points are addressed, then the engine will give it's best, especially if the cylinder-head and valve train have been overhauled.
