Running rich and burning oil?

[HowDoICarbs]

So I think its time I addressed this problem. The first time I started my motorcycle after I crashed, it burned oil for about 5 minutes straight. It looked like I was cooking steak inside my engine because I had white smoke coming out of both exhausts . I figured it must be from the crash since the bike was on its side for a bit. So I left it on and let it burn it all off, and it did stop. I assumed that was that however my motorcycle Reeked of unburnt fuel. And it still does no matter what I do I can always smell the smell of non burnt fuel, and I'm no where near that 52 Mpg mark. If I were to make an educated guess id say I get 10 - 20 miles per gallon of premium gas, and 20 is being generous its probably more like 16. Despite that I also now get an awful knocking sound from inside my clutch cover after I shift into neutral, and today my motorcycle started burning oil again! When I started it up with the choke fully open It had white smoke coming from both exhausts and then it stopped, but when ever I stopped at a stop sign I could see smoke glimmering in my headlight. Keep in mind this was a night ride about 45F out. So I'm at a loss here, maybe it was just my exhaust because the bike was hot I'm not sure. It doesn't get cold here in Arizona often so I'm not used to seeing it. I know for a fact I need more oil because when the bike is on I cant even see it in the sight glass. What do you guys think is wrong here?
