help dont know what kind of bike I have

I dont know what kind of bike I have, where are the numbers or something that would tell me.......the seller said it was a 74kz1000 but I dont see that on the model history

The vin says the model. It should have KZ1000 somewhere in the vin. There should also be a sticker somewhere on the frame listing the build specs, year, make, model, etc. It should also say on your title.

Vin number. By the headlight on the frame. Or on your title.. Then go to kawasaki.com, the owners section, punch in your vin number, and VIOLA!

thanks guys it appears to be a 77 is there anyway I can change my username?

No, you can't change your username, but you only have four posts so yes you can just become a "new" member. You'll lose your post count, a lot of us here are proud of our post counts so cannot or won't change our username (I would like to change mine!)
