So after 8600 miles, I seem to either still have a fair amount of vibration on the throttle grip, or it is perhaps getting worse. Back in the day, people used to say to synchronise throttle bodies or carburetors for such a situation.
Back in May, I had a shop that I respect a LOT do my 6,000 mile service, and am confident they did no less than what the manual calls for. I have never seen nor heard of anyone sychronising the TBs on Americas.
What am I missing here? I am sure I just exposed my fundamental ignorance. Thank you for any forebearance.
