Salam to all, My YBR is now about 4 months old and I am very happy with it. I am getting good average of 45Km/l. But I have noticed a "chuck-chuck" sound form engine when my bike is cold in morning or when I start cold bike. The sound immediately disappears after some time as the engine gets Hot. I discussed it YBR warranty claim mechanic Mr.Amjad and he said that it is normal and bike will do it because engine oil gets cold and settle down some thing like that.
Any other YBR owner facing same problem?
