Might be it's different section related to my question so sorry for that. Now I come to my question At what kilometers we should change our spark plug if installed NGK orginal. Amjad Bhai or any other brother kindly advise. I driven my pakhero ph70 with Original NGK plug 7000 kilometers. Before cleaning of plug bike was not runing smootly and after crossing speed of 50 kmph bike used to give sound like dus dus just like missing so Cleaned it and reinstalled bike is runing fine now as compare to before but some times felt little missing but that dus dus annoying sound is not now so should I change spark plug if I driven alot of kilometers ?
Kindly also tell NGK plug kitnay kilometers tak chal jata hai in chinese 70's ?
