correct jet size

[donk]

Hi Everyone,

I've just upgraded my air filter on a sukida 125cc (pretty sure its a lexmoto scoot with a different skirt on) with a nibbi pipe and 40mm filter on a 24mm stock carburettor.
I already have a performance exhaust so I guess upping the jet is the next logical step.
The stock jet is a 101, so my question is, to what size can I upsize too?
I was thinking 110-115 but would that be too large a jump?
Im at sea level with a few small hills around so not exactly mountain terrain.
The rollers are stock at 13grms but the clutch has been swapped out for the 1500rpm clutch.
I do intend to lower the rollers slightly for a faster takeoff in town traffic.
I hope I've done everything correct so far, any advice on the jets would be greatly appreciated!
Many thanks in advance
