So my dl650 hasn't felt quite as "smooth" as it should. I chalked it up to a slightly loose chain and the touchy fuel injection. I no longer think this is the case after putting about 6k miles on the bike.
I am coming up on my 7.5k mile service, and throttle body sync is one of the scheduled maintenance items. Most people seem to say they are unnecessary or that their bike hasn't needed one. Based on other posts I have read, it seems like I definitely do.
At low throttle inputs, the bike seems to slightly surge. At highway speeds, the issue seems to go away. I held the throttle slightly open at idle the other day and noticed that the RPM's would go up and down within a couple hundred RPM. This seems to explain exactly what I have been feeling at low speeds and coming off idle.
Am I accurate in my reasoning here? I wouldn't question it normally, as it is a scheduled item for maintenance anyway, but most people seem to say they don't need it.
