Aoa,
brother may i ask why? are you planing to change it? if you kindly consult with mr. omer sharif, he is very good mechanic at mcleod road lahore, 0321-7222251 is cell number.
last week my bike's acceleration became very poor like i was riding a 50cc bike, 5th gear with top speed max 60km. so i want to get it checked, he said that the carburator needs cleaning, so when he disassembled the carburator, the slide Diaphragm was worn out.
so he replaced it and yes its expensive the genuine spare's are expensive.
but now its acceleration and performance is excellent. it touches 120km and the fuel is good.
he is very expert person especially 150cc and plus.
He knows a carburator repairing expert, so i will suggest you to consult with him
ALi
