I had a stock one...Glws, a ported 562xp is a helluva thing!
huskihl's video of this saw
That's one angry PS-7310!This is a really good running saw, guys. Just because it's not a 7900 doesn't mean it won't take one's lunch. It's got a pretty snotty attitude that'll pull a 32" bar all day. Smooth as butter
