There is no carb of course - it is fuel injected. I've never had an issue with surge on my '03 650. You are about due for your break-in service, so I would mention it to the dealer at that time. They should probably check for any air leaks at the throttle bodies.

Slow Speed Surge

Two things come to mind what is the idle speed ? Should be 1200 rpm next would be the throtle body sinc. Has to be done by a dealer unless you have the factory manual and a dealer mode switch.

I haven't heard of anyone having a throttle body sync done on an AN650 yet, but it was a common cure for V-Stroms. It is basically the same fuel injection system. I think the ecvt tranny kind of hides the problem if the throttle bodies are a bit off, where with a standard transmission bike you feel it much more. The other occasional issue with the V-Stroms was air leakage at the throttle body boots. Sometimes a backfire would even completely dislodge a boot. I did have a minor low rpm surge on my V-Strom last year - and a throttle body sync did resolve it.
