on mny black road king i'm wondering if there is anything else in addition to what is listed that i should be concerned about or that i should double or triple check on my 2002 road king classic. any advice or experiences would be helpful. also, at 12k is it a good time to go synth or stay will conventional? is there a real disadvantage to conventional? i always used it in my audi, not so with the grand cherokee because its not recommended, but the road king... not sure. it seems it depends on who you ask. thanks.
