Kawasaki LTD400 1982 good place to find parts

Hello,

Im having a hard time finding part for my KZ 400 H1 or LTD 1982 model. most of the parts are for the older straight KZ400, i was wondering if anyone knew any good sites, that sell like rep kits for these KEIHIN carbs also maybe a place where i could find used carbs and parts in general would be greatly appreciated.
