I'm getting ready to put new rubber on my GS850G, and figured that I'd replace the rear wheel bearings, as well as the Head Steering Bearings, upgrade the brake lines, and rebuild the brake calipers.
Found pretty much everything I need to know on the site, as you'd expect, but do have one question regarding brake rotors.
Are the rotors on these bikes something we need to have "turned", or are they a one and done, replace them when doing the brakes, kind of situation?
My rotors appear to be true and aren't grooved or anything. They do show slight signs of "normal" use and heat, but don't appear to have any heat spots, etc.
Just wondering how much I need to order to get all the parts in one place when I order the caliper rebuild parts and brake lines.
Thanks,
