Welcome to the site Shawn..Be careful these KZs are addicting! I think you can find out anything you need to know here.

Check in the filebase, especially here:
kzrider.com/component/option,com_docman/...w/gid,231/Itemid,49/
Welcome to the forum, too!

welcome to z-jungle;) im not sure about your 15hp gain,but a 4 into 1 and some carb rejetting should help id also suggest leavig the baffle inB)

Welcome to KZR! Good to see more Illinoisans (is that even a word? )here. Plenty of useful information to be had here, and TONS of useless info too!

there's a site dedicated to the 550 that might help too, like this one:
