Friends, I have swapped my engine 1000CC to 660cc (JDM) in alto vxr 2004 model, the engine works good, but two problems I am facing:
1- Much noisy sound when I select the gear liver at (P) or (N), there is no noisy sound at (D), (2), (L).
2. While driving a car, it goes to the left side.
Kindly advice me:
