My bike clunks into first gear also, but maybe not as badly as you describe. I've owned about 25 bikes in my lifetime (I own six right now), and my CB1100 makes the most noise of any of them when shifting into first gear from a dead stop,but I still don't think there is any problem with it - (have you ever heard some of these Harleys when they shift into first gear at a traffic light?). Have you checked your chain tension? A loose chair will definitely add to the clunking sound as the slack is suddenly taken out. MY CB1100 is the most sensitive bike I have ever owned with respect to chain tension.
