I have driven a full dress motorcycle for 29,000 miles , yet a still have to
 

slow for corners at 65 mph,? as other motorcycles go around with ease at 75 mph, what am i doing wrong? I tried counter steering, different handle bars.

You don't "turn" a motorcycle at those speeds, you just lean.Look - Lean - Roll - from the motorcycle safety foundation class.Look where you want the bike to go, lean in the direction of the turn (if turning left, lean left), roll on the throttle.Another trick is to push down on the handle bar in the direction of the turn. (if turning left, push down on the left hand grip while leaning)

I am the same way. I don't have the experience you have, but I find myself slowing more that needed coming into curves. I am planning on taking teh MSF experienced rider course this spring. I took the beginner course last spring, and it was a lot of help for a new rider. I think the best advice i got was the counter-steering...as teh instructor said numerous times-press left, look left, go left. you have to press FORWARD on teh left grip to go left. you can't really press too hard. the harder you press, the more you lean teh bike, the faster you can take a curve. press harder, and you WILL make the curve. now with all that said, I have to agree with the other post-Slow down, relax, and enjoy the ride...
