do some research on the kawasaki web sites im sure you will see what others have done .You have to make what you want as these bikes werent factory fitted with any .Me I looked at enough on the web and it seems you can make just about any thing work .but its a matter of finding the style or look you want gathering up the pieces and laying them next to the bike fit up the pieces and make the parts you dont have .like the bracket to bolt the pegs and arms to.or the bar that links the shifter to the pedal exctra. No one can tell you what to do unless someone had your same bike and you do exactly as they did. Geeto is a big kawasaki fan so expect his input soon as he sees this post .Omar has a complete list of rear sets with pictures that will get you in the ball park but you will still need to fittle and fit.
you don't need a welder to make rearsets. Most guys use the passenger peg mounts and a through bolt set of rearsets. Good donors are fzr600s, some triumph, cbr, basically anything that the levers pivot around the foot pegs and attach with one bolt per side. As far as drum, they all should work so long as the mounting tab is below the pedal. just rebend your brake rod and you are in business.
Once you've got the rearset linkage, it's up to you how to set it up for the shift pattern. I think if the linkage is oriented up, you'll retain the standard pattern, if it's down you'll reverse the pattern.
drag bikes and some other race bikes run a reverse pattern because they want to make fast positive upshifts and the length of time on the down shift is less significant. however you set it up just make sure you get used to riding liek that before you try speed shifting, nothing sucks worse than going from 3rd to 2nd at redline instead of 4th.
