jetting wont make it snappy.

I think what happens is if the low throttle settings are off (pilot,mixture screw,slide) then once it comes up onto the properly set midrange(needle,needle position,spray nozzle) it can snap to attention rather quickly.

yes id call that strong mid range and poor running up to 1/4 throttle. (not snappy and most 250s jetting will be close anyway?)

You note your bike is on standard gearing of 10/41.

In New Zealand our Gas Gas was supplied with 11/42.

The taller gearing may smooth the response.

Also make sure you have a slow throttle fitted. 

If a Domino throttle is fitted this would be a black tube under the grip.

A slow throttle has full travel over around one third of a turn, while the fast throttle movement is the same throttle opening over a quarter of a turn.

Hope this helps.

Regards,

Peter.
