anyone extend a kz400 swing arm?

whats up guys, id like to extend the swing arm on my kz400 ltd, just want to make sure im doing it right. has anyone done this before? have ideas as to how i should go about it

or is there an interchangeable swing arm out there from another bike i should look into?

A guy here in Boise did. Are you on dotheton.com?

He is on there, but not sure that he is on here.

if you want to extend the stock one id find another one like it,cut one long and other short and slug/sleeve them together

yea i just picked up an extra one just seeing if anyone maybe had pics of theres i cant find anyones on here to see where they cut it, and if i need to set up a jig or not

also wanted to know what kind of stock i should pick up? i was told chromoly but then i was told that they didnt use that on the bike so im confused.

This forum (Kawasaki Twin Owner's Forum) is very helpful with the 400s. The post in the link is about a KZ400 with a 6" stretch. The OP in that thread (Phil) is a really good guy and is very helpful. He fabbed his own stretched swingarm and I'm sure could get you pointed in the right direction. He is in Cincinnati and I live in Dayton and I've seen his work first-hand. Top-notch worksmanship.

Also, if you only want a minor stretch, the LTD440 swingarm is plug and play and is about 2" over stock. That is what I ran on my old '75 KZ400.

Here's the build thread of the guy here who did it. He extended it 2.5"

It's a bit of a secret, and takes a bit of creativity, but an EL250 swingarm will add about 6" over your stocker. I've seen it on a KZ440, so it should work for you. It is wider at the pivot point so you either have to narrow it, widen the frame, or bottlejack the frame apart a bit. I don't recommend the jack, but have seen it.
