As far as I know neither Haynes nor Clymer make a manual for the EX250. It seems strange, since there's got to be thousands of these EX250's on the road, and they're virtually unchanged since the 80's, like Freakinout said. As far as I know the only service manual available is from the dealer or from www.buykawasaki.com. You'll need the service manual and the supplement.
