humne sab se phle is stock mount ko use kiya to confirm hua k engine is perfectly horizontal for engine + swing arm
then aik aluminum door panel ka sirf panel use kiya on the ground to touches both tires for alignment
aur frame k dono pieces ko engine aur tires k sath hang kar diya chain kuppi pe
due to hanging position its perfectly vertical then place a water level on seating position and bismillah welding
