So, regarding warped rotors, what's the best solution? I had been thinking just plunking down for a brand new oem piece would be the solution, but can the rotor be resurfaced or "turned"? What would be the pros / cons? I know what caused the warpage, so hope to prevent it in the future. (wrong brake pads installed, bad master cylinder..)
Rotor in question is probably a stainless steel one, on my '86 R65.

The difference in thickness from a new rotor to one that is technically out of limits is not very much .
My guess is that to get the rotor 'true' you will have a rotor that is too thin to use .
I have EBC semi-floating steel rotors on my'81 R65 they work great, one member here has them and they wore out at the 'hardware' at the rotor to carrier area in I believe under 40,000 miles .
A company in the Springfield, Ohio area, Speigler Performance, will remove the rotor and rework the carrier and add a semi-floating stainless rotor, which has the capability of being rebuilt, replace the 'hardware' and rotor in probably less than an hours work, if and or when they do need replacing .
OEM rotors are going for over $400US each, EBC around $250US, Speigler around $240US .
You may want to consider replacing the brake lines, if they are rubber and get different pads, there are much better compound pads than OEM out there now.

Is there disadvantage in replacing OEM brake pads with some of the higher tech pads using the OEM rotors?

No problems using aftermarket pads, just don't get all metal pads, they don't work well with stainless rotors .

I'm already past all that stuff, I have SS lines and ebc pads. The rotor is uber warped though. I'll have to look into Speigler. Now would be an opportune time to send off the rotor, since I'm still recovering from a recent pavement surfing episode and the bike needs a bit of maintenance before it can be ridden..
