" kind of a disconcerting "floating" under the back side of the bike."
That IS the feeling, I have decided it is a combination of new tire+surface irregularity+ very likely WIND (I really have only felt it in wide open windswept areas)+and possibly minor front wheel damage. I went to the local shop that mounted my Contis and they were happy to put the bike on a center lift. We thoroughly checked both the front and back wheels and tires, back was right and tight, no unusual movement of the wheel or swing-arm at all, we spun the wheel and it showed no bumps or uneven spots, true and round, we checked for lateral movement, or impact damage of the wheel as well, no observable runout or warpage. The front was much the same, head-race smooth and free of play or "notchiness" wheel spins round and true with one small exception, we noticed a bit of wheel damage, maybe a millimeter and a half max of lateral bend to the wheel itself over about 30 degrees of rotation. I dont think that small amount of damage accounts for what I'm feeling, but it can't help. We have a shop here in Corpus that will true the wheel for $100, which I plan on doing next paycheck. Till then I am going to ride with confidence that nothing is getting ready to fall off my bike, and see if I haven't been making much ado about nothing. I have only owned this bike for a month or so, I have always done my own maintenance and repairs, having been a professional mechanic for one chapter of my life (German cars and all motorcycles) and tend to treat my bikes kind of like aircraft, everything right and tight and wire-tied where applicable! I think an element of mistrust of the previous owner has shaded my confidence a bit, which will fade as I go over the bike and torque every fastener, lube every joint, and get acquainted generally with this beast of a bike. I can tell it will be great, but I NEED to go over it with a fine toothed comb before I feel a high level of comfort i guess, call me crazy!
I'll post back after I have 500+ miles on the Contis and have done the front wheel repair, Thanks again to all who posted, I truly appreciate your insights!
