At 80 it is almost as smooth as a Goldwing, just kidding. Check your motor mounts if the bolts are not torqued you can get a nasty buzz in the floor boards. Tire balance is another major factor and then tuning. When were the plugs changed last?? Usually the resonate bands are fairly narrow so try a little faster or a little slower and see what happens. If you must ride at the speed it occurs a reduction change will help, ie. pulley change. Good luck. Great post, Bob. Answers a question for me about what I experienced this weekend on a NC to GA roundtrip. I was getting strong vibration in my left floorboard @ 80+ mph indicated. I'll check the mounts as I am pretty sure the tire balance is good.

If the vibration goes away, it's your engine. Might be a lean engine condition, or just the nature of your beast.   Logged     Mike V.

If engine, check for a manifold leak using starting fluid squirted toward the rear cylinder and NOT at the carb intake. Ray   Logged     Ray   The administrator has disabled public write access.
