I have an '06 RSTD. Recently, I separated the carbs, cleaned them and rebuilt it. However, I'm unable to sync the carbs because it's not been possible to reduce the idling RPM.
With the carbs reassembled, and off the mcycle, I first adjusted Philips stop screw #1 between carbs 1&2 and Philips screw #2 between carbs 3&4. After that, I adjusted the flathead screw and visually synced the butterfly opening between carb banks 1&2 and 3&4. I do this generally to get to a good starting point to do final adjustments using Carbtune. Also, adjusting the #3 shows how close the TPS can get to idling screw.
However, I'm unable to get the RPMs down to the 1000 range.
I would appreciate any suggestions. Thank you.
