My local dealership sells both Husky and Stihl. He sells the 261performance kit which is a packaged two loops of 63PS and a Picco rim sprocket for $99. The package looks like it would hold a 16" bar, but no bar inside.
He's selling them like hotcakes.
He had 4 new 562's with the new style fuel/oil caps last week , yesterday only 1 left.
