Just like in the 70's...cut open the oil filter!
Aftermarket rods have helped rod bearing life tremendously and saved a lot of money for the racer.
Running the required ring land spacers and thin rings have helped with power and longevity of the rings. Don't forget the rings are usually back-cut for less radial tension but seal better with the newer facings and materials.
Stainless valves will last longer too.
Just like the 70's, check valve lash for problems.
Pay attention to MPH changes.
