Well, the bike started out as a 1985 Kawasaki ZL900 Eliminator. I bought it brand new in 1985. The engine has since been bored, stroked, ported, polished, re-cammed etc. The trans is overcut and undercut for quick shifting. Bill Brutton from Harvey, Illinois out of Fast Bike Engineering built the frame and the engine mods were done from original designs by Dale Walker from Holeshot performance out of Santa Cruz, California. She runs REAL good but the local police usually ask me to take it home if it's on the road after dark.
