Had one of the scariest experiences in my 20+ years of riding. Friday I am coming back home from an afternoon of cruising lil county roads. Had been on the interstate for about 15 miles. The interstate curves and there are a couple exits in the cure so traffic was tight. There was a semi on my left that either dropped or ran over a 2.5 to 3 foot 4x4 piece of lumber sending it into my front tire. The effect was my bike attempting to go down on it's side at 70MPH in traffic. I was able to fight it up and then back straight, but stayed in my lane. Once I had control I pulled off the road to check for damage, and catch my breath. A few guys in cars slowed down and applauded me and gave me the thumbs up (they must ride). I didn't see any damage, at the time and road on home.
I noticed that I had a vibration in the front and figured the impact had knocked a weight loose so I took back roads home at 40 to 50 MPH. Got home had a few beers and decided not to go mess with it til morning. Saturday morning I went out to take the front tire off and get it to the local shop. As I was taking off the tire I noticed there were no weights missing, the tire was low(15psi) and there is damage to the faring and belly-pan. Both have large cracks in them with the belly-pan actually being broken at the attachment points. Went through the whole bike and found the shifter lever is bent and loose and, one of the side covers that runs below the seat is cracked, had to be from the death grip my legs put on it to stay up.
Insurance people are to look at it Monday. It will for sure need new tires, left fairing, belly pan, side cover, and shifter linkage. Have to take it to the shop to see what else. I am thinking possible new wheels if they were knocked out of round. I am hoping repairs won't exceed the value.

As for me, I was shaken but not spilled, so all is well.
Anyone have any other suggestions as to what kind of damage to look for and how to assess it?
