Salam.
Guys I own 70cc super power (2006 model). It has star head. The sprocket are not genuine as my mechanic fitted some time ago but I don't remember their number (I think they are 14-36...maybe). Everything else is genuine even engine is sealed.
But the problem is that my bike heats up very quickly and the max speed becomes 30-40 after 1 hour of fast riding. I change oil every month and the bike is in good shape overall. Is there any solution for the excessive heating? maybe the sprockets settings?
I would really appreciate your help. Thanks.
