@ lord of isb
you have altered the bore of GTO110, surakh bara kar kay GTO125 ka piston to daal dia hay but your GTO110 would not become GTO125, you would spend a lot of money but it wount become orignal. The differences are in Headlight., Meter, Tank, Sidecover, seat and backcover and if you do all the alterations, your bike would be identified by small rear brake drum, small engine head, engine and chassis number which would show 110
