Sv650s 2008 hunting/surging btw 3k-4k!!! Arrrgh

Is it my bike or do the later twin plug euro bikes hunt/surge between 3000-4000 rev range? On constant throttle at that rev range my bike just want settle, jerking and so on, especially in 2nd/3rd gear.
Anyone know about this? The bike has only done 6500 miles and has been meticulously maintained.
Many thanks

If it helps, there is no surging as you describe on my twin spark with about the same mileage. I would try a tank of super unleaded before anything else.

At those rpm in 2nd/3rd gear, you're probably using only very light throttle, which could highlight the throttle bodies perhaps being very slightly out of sync. Check the caps / tubes on the TB sync stubs aren't cracked or leaking. Has the TPS set-up been checked recently?

Might also be worth checking the spark plugs are nipped up snugly, they can and do loosen in use.
