Its been 15 years since i had my 125 (as all of 5 friends have and we live in Lahore).
Honda have dealer ships in All over Pakistan...???. However company dealerships are not famous for good tuning/modification, they are usually good for routine maintenance and good part, On the other hand there is one famous mechanic in city which every bike lover knows, so dig it out and get your bike repaired from him.
However Honda carburetor and due to Pakistani fuel you need to get it cleaned fully after 10,000 km or when the bike loses economy and performance
