Carb set up advice

Hi guys
I need to upgrade the guts of my carb. Any chance someone can give me a pointer to jetting's/pilot/needle/slide requirements etc.?  
Details are:
  • Dellorto PHBH 30
  • Vespa PX200 late engine
  • Casings ported/matched and fitted with Malossi 210
  • T5 4th gear
  • SIP HP4 flywheel (might put original back but not sure it would make a difference to carb set up)
  • JL Right hand (under engine) stainless pipe
Appreciate your help. Also I may reedvalve it later so would I need to make any changes then?
Cheers all - stay safe
