Spluttering mallosi 210

Hi guys!
Help me out here. Got a new PX200, fitted Mallosi 210 & scorpian exhaust. Modified head & standard carb with 125 main jet.
The problem is she splutters badly at mid revs until she hits powerband. Tick over is ok, so is low revs.
Why?? Can anybody help??

Nice 1 Lost Boys!!
Put the 118 jet in, shes running spot on now! [:smile:] [:dance1:] [:D]
Suppose i will have to have the ports matched if I want to up jet.
