The reason for my swap is my ‘95 zr700 broke the bulkhead in two spots and the tunnel rivets are coming out by the chaincase.you will have to change the jackshaft bearing/ rear motor mount support every time going from twin to triple or vice versa.
maybe the jackshaft also. have to verify part numbers.
the rest of the motor mounts.
depending on the where the mount bolt holes line up in the chasiss
you may have to install threaded inserts in the frame
Here’s a couple pictures of the breaks.I would put your good engine into the good chassis.
Your old bulkhead probably has the front cooler welded .
Engine swap seems a lot easier without seeing them .
Appreciate your advice. I’ll go ahead with the swap then. Definitely don’t want my sled to fold up on the trail and injure me or anyone else.i disagree.
throwing good money away
your old chassis has broken already.
it has been weakened
the repairs will hold, but the chassis will crack again on the edges of the new welds.
seen it happen more than 15 times.
it is up to you, your sled
your time and money
