I used to work for the distributor of Pingel petcocks and they are defintely not only for Harley's. They started in the dragbike business and continue to make a crapload of petcocks. I will not have my KLR until next Wed. so I can't check but if you visit http://www.pingelonline.com/fuel_system_accessories.htm I am sure you can find an adapter plate that will work.
