I have an 09 RSTD. With about 1000 miles on it, I started noticing the exhaust popping when decelerating and with information gained from this site, I plugged the AIS with stoppers. This solved the popping issue.
Now, with about 3500 miles on the bike I want to sync the carbs. Do I need to unplug the AIS or can I just sync with the stoppers in place? Bike seems to be running fine just has never had the carbs checked.
Thanks in advance for the advice.
