Husqvarna 2011 Husky Wr250.. Help???

My buddy has a 2011 wr250 and some problems have come about. 1. Broken flywheel magnet. 2. Damaged lower fork tube.
Where in hell/on earth do you find parts for these damn bikes? No listing for either part. Although he said he found the fork tube for $500. Any good fork swaps that will allow the use of stock wheel and brake? Thanks

He was still selling huskies back then. Also, Halls in Indiana I believe. WWW http is a wonderful thing.
