Kawasaki Lakota Sport Mod ?'s

I am looking for new parts and aftermarket parts of my 03' Lakota Sport (kef300-b3). On the aftermarket stuff I am looking for a bigger gas tank and the rear and/or front racks. Does anyone know a place I can find this stuff, preferably used so it's cheaper? or any other aftermarket stuff for this bike?

The Lakota I Used To Have I Got A Aftermarkt Pipe From Cobra And Some Nerfs Form Dg, And Some Nuckle Busters From Some Damn Where.
