Oh good. When I read "overhaul" I was expecting to see split cases, pistons in hand, etc. As far as comments, just a few...
1) I always prefer "rotor friendly" pads. The price of replacement rotors is over the moon.
2) Air filter renewal time is greatly influenced by where you ride. My 1/2 mile gravel drive assures plenty of dust. There is probably some "rule" against it, but I have a low pressure compressed air tool that is designed for blowing out Donaldson air filters. The filters on my farm equipment get blown out dozens of times between changes. It is a little more "iffy" here since there is no "safety filter" behind it, but I wouldn't be against carefully cleaning a filter to extend its service life.
3) Brake fluid exchange is one of the most overlooked services. It really does make a difference. I do mine every year, but every two years is probably fine.
4) I am not a believer in Fram filters, but I can't say I ever heard of any damage caused by one. I just don't like the construction when I see the internals of one that has been opened up. I would bet you could run without a filter if you changed the oil regularly and do no harm. That is the way all motorcycles used to run. OK, there was often a little slinger, but often not even that. I am an OEM oil filter guy, changed every other time, but I don't preach it.
5) I am not sure that brand of sprockets is a big deal. I just buy the chain and sprocket sets from Sprocket Center. I expect that rear sprockets could go two chains. I would always change the front sprocket with a chain regardless of how it looked.
