hey guys i have a 1998 c400 and was wondering what years and motors are interchangable with this motor? brought bike with motor already torn down was handed a shop repair manual managed to put the bottom end back together but having trouble with the top end and still have a jar full of bolts. would i be able to pull the gears from the bottom end and place them in the cases of a early 2000's motor casing? only asking because every repair shop i call gets scared as soon as i say 1998 husaberg and refer me to call the dealer.
