Value of Engine Balancing

[Nick Turley]

Hi Colin

What you state applies to V8s, flat twins, v twins and such like for which balancing is a tricky  topic often not much understood by many doing it! But not required for symmetrical inlines etc. 


And Nick
I am curious that new cranks are significantly out of balance dynamically. Hopefully are at least in static balance!

Balancing here was an expensive process, in large part because the local practioner instead of working to commercial tolerances persisted to the limits of his machine.

(Unrelated to our engines, but let loose on flat twins he expensively removed vast material making the engines much less smooth then originally!)

The cranks I have had are in balance statically but not dynamically Bob
