All else being equal between your two bikes and having done carbs on/off and engine swaps before, there is a lot more work and expertise needed IMO to R&R engines than to just swap body and accessories between bikes, especially since you're going to have to pull a lot of the plastics from both bikes to change out the engine anyway.

Any farkle swapping that is needed will be relatively easy as most are bolt on and / or wiring in scenarios (nod to your 'harbor freight' comment!)

Sounds like a fun project.    >:D

Keep us posted.

What kind of damage did the hydrolock do? Often they can be repaired. If it bent a rod, you'll have to pull the motor out anyway.

But, if it don't have a bent rod, why not keep the ugly one to ride for right now and keep the pretty one to work on and repair at your leisure?

David, IMHO i would put the ugly motor in the hydro bike.
Just me.
Where are you located? Could be up for help if not too far from Western NC.
Thought I'd throw that out.

Only if its rod 1 or 4.

Rods 2 and 3 can be done without pulling the motor or splitting the cases.

Are both bikes currently titled and registered?  The VIN on the frame may become the deciding factor.

e bay has some used Factory Service manuals. Be careful of the location. I would get one and read through the engine removal and see if this is something you want to tackle. I took the motor out of my Z1 900. I know it's not the same bike but it was pretty straight forward.
