Salam all ! I bought a new united us 125 euro 2 bike 2 days ago from akber road karachi.. I really like it ... But i'm so confused about it's engine and chachis number , they both are same eg; engine number 12345 and chachis number 12345.. I just want to ask that is this ok or i should worry about that.. And also i found rust (zang) inside it's fuel tank ... Waiting for the replies .. Sorry for bad english and pics coming soon.. JazakAllah..
