partially stripped cover bolts

i just bought an 1981 csr1000 m1 and am having trouble finding replacement bolts for the engine covers, i am willing to buy a whole kit so as i remove bolts i can replace them, i did find one site that sold them but they only went up to 1980 kz 1000 models, boo to them somebody give me some info

I got my cover bolts from Z1 www.z1enterprises.com/catalog.aspx?pid=XX110

Made my own kit, took a few minutes to put together using the WWW.Kawasaki parts page and Z1

got the bolt kit for everything on the motor even exhaust flanges in the allen style in stainless, ebay for 27 bucks
