I synch'd the carbs and saw no improvemet. I went through all of the threads here at Venturerider.org again and one noted how one of the contributors pointed out the importance of calibrating the tool and how to calibrate it. I calibrated my Motionpro Carb Synch tool and found although it was new out of the box, the #3 bar was way lower than 1, 2 and 4. So after adjusting the tool, I re-synch'd the carbs the and now the '05 RSTD runs like new. I suspect my milegae will improve back up to 45 mpg as it fell down to 38 mpg after the carbs fell out of synch. Thanks for all the great posts here.
