Man I hate to hear this kinda crap. I am sorry for this man. I feel your pain. I lost my first bike to these bastids.
The insurance process can take a little time. It seems frustrating, but there are ways to speed it up. What they generally look for are pics of the bike, list of mods, and prices on similar bikes. So do a search and find some upper end prices, some mid range prices, and low range prices. They will also need the milage on the bike. Low ball it. They take a chunk off for milage too.
If you have all this lined up, the process goes a lot quicker. It took me 3 weeks to get a check with everything lined up. And with the appropriate price checks (aim high) I got my bike paid off plus about 900 bucks. Just sucked to be without.
Best of luck man, and if you got any questions I will do my best to answer.
