I un-assembled the fuel guage by opening the nuts at the back due to which the whole guage (opened) was in my hand and i didn't know what to do. I got it assembled back perfectly but now the calibration of the fuel guage & speedo pointer both are not properly calibrated.
Speedo shows 0 on 20, 40 on 60, 80 on 100 etc
and fuel is empty when the pointer is still above E -_-
