last sunday say mairay paas 150 main prob arahi hay, hoa ye tha kay office jatay hoye bike missing kar rahi thi, wapis atay hoye bilkul hi band hogai, ghar kay paas chek karai to bataya kay ignition coil ka prob hay wo change kardo set hojaeygi, aaj mainay coil lagwai bike set hogai, but aaaj jab office say wapis anay laga then phir wohi problem start hogai, yani bike start hojati hay but jaisay hi race denay lago band hojaeygi, ek week say is beemari main mubtala hay, koi dost hay jo iska hal bata sakay.
check the plug wire or may be tunning is due and again let it check by electrician who knows about coil issue. coil prob is very obvious in 150. coil of honda cd 100 also compatible with 150, i have experienced the same issue with my last suzuki...
problem solved, and the issue is replaced the CDI, many thanks friends.
Special thanks to Junaid Akhter pakwheel member, he helped me allot. and a very nice person. and the mechanic Jahangir and his crew. and my friend and colleague Shoaib Ali.
