modifications did you need to do to the headlight to make it fit?
Nothing you cannot do with a hacksaw,drilling machine and hammer. The main problem is, that there is a hole in the original headlight at the bottom. The original headlight is pinned on metal pin underneath the headlight. So you have to drill that hole in the new headlight.
The second problem ist that there it not enought room at the back part of the headlight because of the ignition switch... So you have to deform the back of the headlight that it fits.. i used a hammer

it worked. It does not look good but you cannot see it whe the headlight is installed.
Plate holder is form Valtermoto (ebay). It ist the same as for mt07. There ist just 1,5 (!)cm beween the wheel and the plateholder. Scary. I will post a picture ...
