Good evening gentlemen 

 

I was riding my bike in the track with a leaking water pump,, the bike got overheated and suddenly it lost all the power (it feels like i'm dragging ton of stones behind me) with a backfiring !

 

I took it home changed the water pump seals,, checked the valve clearance, timing chain, piston compression and spark plug every thing was good ! but it still having the problem

 

what might be wrong with it ??

 

Thanks in advance
