HI there Pakwheelers, been a long while since I last made a post. I have a Super Power SP 125 my daily commute is around 70 km altogether on this bike. The problem I am facing is that its engine doesn't feel like a 125 engine, makes noise like a 125 but its power is like a 70cc bike, can you tell me what can I do to improve it? I have got its engine overhauled, the engine weight had some trouble, I got that fixed and put in another head cylinder with a new piston, I get its oil changed every month like I don't compromise on the maintenance I always keep my bike maintained because I don't like a rusty bike that looks like it'll fall apart at any time.
As I stated earlier it doesn't feel like a 125cc bike it seems like the bike has no power, changed the carburetor to Honda's, and changed its clutch plates and pressure plates too but still no difference got NGK iridium spark plug with Honda's CDI but still no difference the bike hardly goes up to 70 or 80 km/h speed and after that seems like the engine is struggling to drag itself more feels like the bike is trying to stop itself I can't explain the phenomena exactly but idk what to do with it anymore, don't wanna sell it and buy a Honda because I live in Karachi and Honda is more prone to being snatched and stolen and I want speed and power because my office shift ends at 2:30 in the night and I have to travel from Clifton (Do talwar) to Gulzar e hijri Scheme 33 and you know how things are like in Karachi city so I need enough speed and power in the bike to get out from any sketchy situation (May Allah keep us all safe from situations like this)
I thought yesterday of swapping its engine with the sleeper 125cc engine. Still, I don't know where to get it and how much will it cost I am confused about what to do because an engine swap would cost me more but if I can get this engine fixed properly I would be happier to do that.
Please suggest to me what should I do.
