I have an old Mehran and overhauled engine 2 times now it again has some problems now I want to swap engine. I visited pindi last saturday and found F6A 660cc 6 gear EFI engine for Mehran for 40K with all fittings. My old engine will also get me some money back. I planned to do it on sunday but just hold for next week to first ask from you people here. Is its price worth it and will it be a good idea to swap?? Has anyone experienced such a swap? Please suggest me.
