Try Beartooth Kawasaki for new parts. If you join their forum they give you a discount off of list.

FYI, motrocycles and parts are duty free into Canada, just don't get them shipped by anything other than USPS as the shipping firms, like Fedex, will charge you a clearance fee.
I use a drop center across the border and then drive over and pick up the parts. Usually the Customs guys don't make me pay the GST.
