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

 

160

BE3

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
