z1 - j engine swap

Hello. I would like to enquire please, If it's possible to swap a z1 engine into a 1982 ltd frame that has the j engine?
I am currently looking at an Ltd that's up for sale. It may be a future project.
Many Thanks.Mike

Don't think you can,,,,,,,,,,Z1 motors have a kick start and that makes them a bit longer that J motors. Either way It certainly won't be a straight swap

I've seen the opposite swap: J-model in earlier frame. If I can remember correctly, the rear mounts and maybe the side mounts are the sane but front mounts are different.

Later, Doug

You would have to be a good fabricator. I bought a J bike with a KZ engine sitting in it and the only mount that was bolted was the rear one.
