1977 frame w\ 1980 ltd driveline

i have found my frame on a 1980 kz 1000b ltd is twisted . i found a 1977 with a beginning vin kt00a looks very close only thing different thats obvious is the way the rear peg brackets are. what i am asking is will every thing bolt on or is it a lot of headaches

From what I understand 76-80 is pretty much the same with minor changes. So yes it will bolt together.

Make sure the frame has a brake pedal.

Thanks for asking this question. I was just about to ask basically the same thing. I have a 77 frame and i just got a 79 police bike I plan on pulling the motor to build my 77.

I have '77 and '82 KZ1000s. The places that are going to jam you are are all 'external' to the block.
- The triple tree areas are different. I discovered this while trying to install a Vetter fairing.
- The carbs are different, so the placement of the fuel petcock has to change.
- The tank mounts are totally different.
- The seat mounts are close, but may require some detailed engineering.
- The side cover mounts are a little different.
- The tail stock and fender mounts are a little different.
- The passenger pegs on the newer frames are on a 'bolt on' spacer. The old frame has fixed foot peg mounts.
- I might be mis-remembering this, but it seems to me that the swing are pivot width is a little different (240mm vs 230mm).

The frame has some additional gussets and the frame tubes on the top are a little bigger.

I bought and put a 76 reproduction seat on my 80 and it fit's like it's supposed to. You are talking 77 and 82, anything after 80 is different and his is an 80 model.

The problem I ran into (I swapped the seats by accident) was the latch loop. On the old bike it was adjusted different than on the new bike. It seems to me (and it's been a while) that there was also a pivot lock on one and a spring operated spring latch to hold it open on the other.

It wasn't a big issue and it all more or less fit, but it was enough that I realized I swapped the seats.

It was all in the details, which was entirely the point I was trying to make.

Pre 76 might use the plunger style seat latch, but 76 to 80 share the same latch style U-bolt.
