hi, ive a px125/polini 177 iron barrel , with mazzy polished crank/rod,mallosi inlet n mallosi down n forrad pipe , inlet n cases matched n barrel packed up by .5mm . it came with a phbl carb ,24mm , with 50 pilot,40 slide , aq264 mixer an d22 needle on 3rd notch down .
the kit an inlet had been just bolted on before an are now matched ,was running despite a blown clutch seal , i'm happy for now with pilot n slide as it starts n picks up from tickover ok , next is dialling in the other jetting . other info i can find is mostly from 24/24 spaco's ,or 28mm dells n better spec engines (worb5) ,
my question is ,does that main seem small to anybody else , i was thinkin more in the 115-120 range , an guys with 28's seem to be up in the 130-135 range ,
an same with needle/atomiser , anybody got any ballpark figures i can start from an get on the road n fine tune from , H
