Bro what u can do in 70 cc bike is u can alter them by body kit. i'm not sure in lahore but i used to be karachi . Alteration kit which includes tanki taape in new style front and back mud guards in new style, head light case, horns , indicators ,handle, Meter, seat. which i s totally different from local market stocks after that you can alter you bike engine with using alter chain spocket set. front will 17T and back will be 34. it helps u to have long gear shifting. Means u can increase top speed. normally we used 14 front and rear 32. or if you want to increase more speed of your 70 cc bike then u can use air filter of Honda pointer 50 cc. it will increase shoot. change your bike silencer it will help in increasing average. it will help bro. but after that just one thing if you want to increase your bike life then never make alteration in your bike.
