There are a couple of issues with the Wee, but the EFI itself is just sensitive, not jerky - these might also apply to your current bike.
New, yes, it's jerky. After about 1000km's that went away.
That leaves issue #2:
Stock the front suspension is soft and underdamped - I thought it was jerky EFI until I did some suspension work - what was happening is that the throttle was moving under my hand every time I hit a bump, which made the bike jerk, which made the throttle move, which made the EFI seem jerky - that fixed and it's fine.
Still needs a delicate touch, but it's tractable enough to cope with nasty offroad - so probably O.K. once run in.
The Wee was carbed from the get-go
so no get out of jail there.
