Jetting advice

Hi all,

struggling to get my PX125 2005 with Mallossi 166 running right. I have a SIP twin exhaust and spaco SI 24/24E carb. Terrible idle, extremely boggy when pulling away and top end speed of around 45mph


my jetting is




114 main jet


56-160 pilot

60 starter jet


plug is ngk B9ES

not sure if the porting was done as it was fitted before I bought it  air filter is drilled

Thanks for looking  


hi peedy17 i bought malossi 166 mk3 they supplied two main jets 105/106 for non ported and 115/116 for fully ported but i think they were for original carb and not 24mm if thats any help
