Ap na Kis bike pa lagana ha our kion?it's only good for altered bikes as it has bigger venturi and allows more air to go to engine whose bore is increased. The difference between 1 nmbr and 2 number is hardly 1-2kmpl less mileage on 2 nmbr( from my experience on cHonda altered to 110cc ) . And slightly poor quality of metal or fitting. Petrol ka nozzle nikal jatha ha aksar but after Magix depoxy it will never come out again..
