Hi guys

I'm looking for a bit of advice
I'm about to put a deposit on a second hand Transalp 2012
Had a test ride on a local bike today and had a bit of a problem with it.
The throttle response at low revs seemed a bit jerky.
Almost like it was dying as I shut the throttle down
Then sort of surged as I opened it up.
I found on roundabouts I had to slip the clutch to get round cleanly.
It was Ok on normal pulling away, and only seemed to happen
when I shut the throttle down then tried to open it up again slowly.

Is this normal on these bikes?
I'm wondering if it's just a Fi Vtwin thing
and I just need to get used to it,
or if there was some fault with the bike I rode today.

Cheers Dog
