I am talking about bikes from the 50's and they still on the streets with no problem
. So just change your oil often and make sure you put oil again don't just run with out oil. Just saying

And what condition are they in, and how many times have they been rebuilt?
Comparing a flatty/Pan/Shovel to an Evo or TC engine is like comparing a Boss Hoss to a Big Wheel.
Pans and Shovels use 60 or 70 wt oil. No multi-visclosity oils. In severe cold, you can run 30wt. Not gonna see that in Cuba.
You can run straight weights in Evos and TC engines but the tolerances and oiling is improved far beyond older engines, now allowing multi-viscosity oils.
Its not "going crazy" about oil, rather being properly educated and understanding why the manufacturer recommends one thing, and using something else to save a few pennies may not be the best idea or a well informed decision.
Yes, you could run just any old oil in your engine. However, I'd be willing to bet money on a decreased longevity. Using anything not rated for an engine is never a good idea.
