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
