SilverBack is ROCK SOLID! I just had my Monster in there this last winter for a hand full of maintenance things and ended up doing a few more performance mods. Their prices are fair and they are very clear about you're options and price ranges.
And to anyone who will need maintenance done before next riding season, Silverback really appreciates any off season work they can get.
During the 12k maintenance I had them lighten my flywheel and open the airbox. Then had a them tune my Stock ECU with there new... not 100% sure what it was called, but I think it was an Alientech.
