Shudder or maybe unbalanced tire question

[Putts255]

Yup the dynabeads do fit in the tube.  They are actually much smaller than I thought.  

I went for another long ride today.  The bike rides better with the beads but same vibration at around 3200 to 3300 RPMs.  Bike does not even need to be in motion if I just rev it it vibrates at those RPM's.  

I will go over the bike the next few nights after work.  Will check the suggestions.

Overall the bike runs really nice and is a relatively a dream to ride.  The vibration has me a little concerned and question why it is evident this year is all.

I will keep you all posted how I make out.
