It's also much easier to do a trial assembly to check conrod centrality in the cylinders and a crank end-float check.
Managed to disassemble last time, won't be doing it again before I am in the dirt (as dust!). Before 3 piece bearings, was not a huge issue. If it had been I am sure Trumphy would have inserted them prior to 1979. Progress is good, but not necessarily great!
When the engine was assembled back in 1976/77 I often ponder how the assemblers measured conrod centrality and C/shaft end float when busily assembling all these engines. That, subsequently were thrashed, mistreated and generally given a hard time yet, 30 years later show very little signs of wear.
