OK guys thanks very much for your responses...
I'll try the screwdriver listening idea for the throttle plate shaft wear issues. I am the second owner I purchased this bike used 6 years ago with 30,000 miles on it. The bike is an April 2004 build date. And of course the first thing I did after falling in love with it was to peruse the internet for 'upgrades'. Lol....
The symptoms I am relaying started about two years ago when I think about it. It was so minor I didn't pay any attention to it and it has gotten worse over the last two years to now being a problem.
