I "aren't" one of "them" inginears, couldn't spell it yesterday either...
The harmonic is only from 2500 to 2700, how could running the engine on a steel plate possibly wipe out the bearings if the engine is not run in that range ?
I guess I'll have to change my steel plate mount for my 289cc twin racing engine to a 2x6 so the bearings won't get wiped out during testing...NOT....
