Hello all! I'm located in Alberta and just picked up my 1975 KZ400 yesterday, I'll post pictures as soon as it's off the truck, it's complete but it is in pieces which I have to try and put back together, I'll have to look through some of the categories and see if I can find assembly instructions!

Howdy. KZ400.com has lots of info, including a factory service manual. Should be lots of help here too.
Warning: the KZ400 site forums may harm your computer. This was a problem reported by others several years ago. not sure if it still is. but I wouldn't venture into them.

Thanks! I came across that site when I first found the bike but haven't really looked around it much but I'll definitely check it out.

Welcome aboard! Yeah, a manual is a must. i’m pretty sure you can get a PDF online.
