what frame can i use for an 80 KZ750 motor?

I have a complete kz750 that someone ( NOT ME LOL ) cut the frame to make a bobber and it didnt turn the way i wanted so now looking for a frame that i can use to swap my all my 80 kz750 parts to.. i found a 82 frame but not sure what years and what size motor frame will take my motor.. thanks for the help guys...

Is it a Twin or 4-cyl?

If it's a KZ750 twin engine, your limited to that line of frames. If it's a KZ750 inline 4 engine, any KZ 650/750 frame will work. Even the early air-cooled gpz rubber mount frames.

is a 4 cyl. in line. Is an 80 i found few frames with title but non of them is 80.. this is what i found so far:
82 kz750 frame
77 kz750 frame
83 kz750 frame
77 kz650C frame
82 kx750N frame
so not sure what years frame will work with my 80 Kz750 parts..

Yes the KZ750 came in two variants. A 2 cylinder and a 4 cylinder. If your bike has four exhaust pipes off the engine, then it's a inline 4. If that is the case, you can use any KZ750 or KZ650 frames stated in the previous post above.

If it is a twin cylinder engine, you will need to locate another KZ750 twin frame.

1980 is the first year of the 750mfour cylinder so any 750 made before then wont work.

also, i believe in 82 they made both, so without the model letter really cant answer if the frames work or not

yes there are 4 exhaust pipes and 4 carbs. so any newer than 80 will work?

Any KZ750 frame except the following:

76-79 KZ750B
1980 KZ750G
1982 KZ750M
1983 KZ750K
1984 KZ750K (Canada only for 84).

The above will not work with a 750 four cylinder motor (not without a lot of work anyway).

Is the bike an Ltd or Standard? You can check a 17-digit VIN at Kawasaki.com.
Ltd = Chrome headlight bucket, chain guard & other stuff.

Ltd: the easiest swap to match all of your other parts would be the 80-83 KZ750-H Ltd models or 81-83 KZ650-CSR . Their frames are virtually identical. (note: the 1980 & earlier 650 models are quite a bit different --- your engine would fit, but not a lot of the other stuff).

If it's a 750E Standard the best fit = 80-82 KZ750-E models. And maybe the later standard models: GPzs, 83 750-L3 & 84 KZ700. The 750-H & 650-CSR frames would probably work, but you may have to get some different brackets n stuff for this n that.
