Makes sense to me AP... Hadn't thought of doing the sprocket change, but it makes sense...
I hardly need to do it given how fast the saw cuts as it is, but I wonder if it would make sense to go up on my Dolmar 7900 when I'm running the 20" bar?? - With the stock sprocket I have absolutely no trouble running the 20" bar at full throttle, it doesn't even slow down going through a red oak trunk... I could probably go up a tooth, but would the increased chain speed be too much of a good thing?
In terms of filing the rakers, I find that I need to do them every 3-5 hand filings or so, and IMHO this is one of the better reasons to hand file - I don't know about other shops, but neither of the two places where I used to get my chains ground would touch the rakers. (One was the local True Value hardware store, that sells some Husky and Stihl saws, and the other is my neighborhood OPE guy, who works on everything smaller than a riding tractor... Neither is a "saw shop" as such)
