I would agree with what Zach said, your bar may need to be surfaced, "trued" up or the cutters on the chain are uneven. My MS 390 is on its original 20" bar, but one side is a little off, so its reversed, guy at the saw shop can surface it for me, and one of my chains was off as well, I was either off with the bar clamp guide or who knows what, had that one sharpened on his grinder, and got 2 new ones, so I tried a new one and have sharpened that with an accurate bar clamp file guide, still cuts straight. Its a typical scenario with these, and usually a simple fix. I've learned, accurately sharpened chains, clean air breathers, and keeping them sharp, makes a lot of difference. Hard to say how the bars get uneven, but over time, varying conditions, use, it may happen. I run decent bar oil, stihl, husqvarna, mostly stihl, does not fling off, oiler screw turned to maximum, I'd like to believe the chains and bars will last longer LOL !
This condition sucks when felling, the darned thing will bind up in a cut and even if you have a sharp chain, if its off and or the bar, saw engine works twice as hard to do half the work, in my humble opinion and you know what those are worth LOL !
