Hello all, my name is Dan otherwise known as Butch. I thought I would join thumpertalk and give it a go! I recently swapped at 2001 husqvarna cr 125 for this wr400/426 problem is the frame number is kCj01w - 004580x and doesn't display on any vin checks.. also I need to replace the stator, in which I am mechanically sound. But I don't know what year the thing is or even if its the 400 or 426. Any help would be great. Thank you all in advance. Butch.
