First of all on buying a good ride CONGRATULATIONS
I know many people have same bike and they all are happy and are not in mood to change the ride any time soon. I have heard that Its really a great bike in this budget.
I would say don't change originals, you have changed the Headlight, That HID would have fit in the original one as well, any way you have changed it and looks good. I have Superpower 125, which has the same headlight and I m not happy with the same, although electrician has promised to install HID in it for me or I may replace that with GS-150 Headlight.
