1 ) Cam is finished and needs replacement
I have two choices
first choice is brand new i asked a shop keeper form lahore and he is offering me a cam of taiwan for Rs 2000
and other one is a person on facebook page he is offering me kabli cam for 5000 Rs
2 ) Crank is also damaged and is woren out (kaat ho gaie hy according to khradiya)
Connecting rods are available in market (brand new)
kabli crank is also available for 8000 from Mr ZKZK of roadmaster group
Last option is to weld the crank sides with steel and then make its size with sleeve
3 ) bearings are loose and needs replacement
Bearings may be repaired too, and khradiya also forwarded me to a bearing shop where i can get bearing of my choice
piston is ok and just needs sleeve and rings only
