Honestly for most people/saws I've run into a consistently clean air filter and sharp chain is what most should be worried about. Not saying The Treehousers are in that category as I've met precious few, but most saws I've seen at other companys are badly in need of some basic, basic maintenance.
My personal saws are clean and sharp, but try to convince my employer to let his fellas clean and file the saws at the end of a day or early in the morning before work....HAH! All our saw maintenance to be done on site...and then he complains about service bills from our dealer because we're not allowed to do it ourselves, puhlease.
I've not ever run a modded saw...apart from a 200t without arrester, one day!
