There is such a thing as saw fit run one daily like that's ya job to do so well your muscles build ya get stronger
no bull.. Anyone who calls a 066/661 a big saw is dreaming! lol or doesn't use one much that's fine but is better to have a more realistic view some people actually run saws for a living the blanket statements like that saw's too heavy to run more than an hr will wear you down! says who? the couch potato?!? lol ...I bet none of us could drive an F1 race car but guess what many men do and its there job no bull hey lol...
Now a loud saw is a loud saw there is no getting used to that well until your lost half of your hearing that is, but that takes time so not really a quick fix going deaf to block out an overly loud exhaust note haha..
And how times change was only few years ago one would get hunted off AS for running .404 ya know its too slow blah blah but now seems its the new blue oil tis good stuff! lol. I've run .404 for over 20 years and can honestly say as some have released its good stuff on a 90+cc saw if you get used to the ins and outs of running .404 good luck going back to 3/8 its crap as far durability goes, it doesn't take too long to realize there is no real advantage of going back to 3/8 more an eye opener to 3/8 chain shortcomings...Ah and I'm not talking race saw stuff talking getting chit done 6hrs on a saw day in day out done, most the guys that knock .404 have never run it lol..
As far as .404 is hard on crank bearings I've not seen that myself in stock saws with well past their use by date hr's on them..now a overstressed ported saw I guess it would add stress to crank bearings that's a give in .404 takes some pulling in hardwoods and can be ruff on man and machine but personally I've not seen any problems with stock 90cc saws over the years...
And no not intentions to upset anyone just saying and is only my 2c on things that don't really matter
..
Hmm think I posted this in the right thread donno
