bike specs?

Where do you guys get your specs for HP from? I'd like to be able to look through the years of say, the 550's and 750-4's and see how the HP changed from year to year.

bikez.com seems to have some, but it appears to be a little disorganized.

The KZ manuals all have a tech section with specs for the bike including hp.bj

As hocbj23 says, the factory service manual has it, (but not the one in my signature). Then there are old motorcycle magazines that will have it too.

Check out this link www.cyclechaos.com/wiki/List_of_Kawasaki_motorcycles#KZ it does list claimed HP for most of the bikes listed.
