Fix it - I did
I have been through this process a couple of times and fixed it myself (had help the first time from Mike A).
I bashed my bike almost as bad as yours twice - replaced the plastics fairings, new engine crash bars, new front fender, new wind shield, new or straightened the headlight mount, new shift foot lever, new handlebar mount and bolts, loosened the forks and rotated them back into place.
Ordered new original KTM parts through KTM twins or the Motor Cafe in Sunnyvale. Most parts took a week to arrive - the only exception was the handlebar mount which took six weeks.
I am guessing the headlight not working is the connector popped out or the bulb got damaged. Easy to check.
This is easy bolt on repair - and can be fun to do yourself - give me a call tonite and I can help you.
