Here is a video - the bike was mostly torn down though before the engine was removed. There may be some useful info though.
This actually sounds like it may be the best option assuming the pistons aren’t damaged. You know/assume your SweetTreat block is in good condition as you’ve done all the maintenance while you don’t know everything about the donor engine (and it’s unlikely you can fire up the donor engine to see if it runs properly on an engine stand- also, was the donor bike on its side as a donor, such that maybe it was running and oil starved? Again, just a thought). If you have just have valve and water pump failure, I would agree with the above opinion, as it’s much less work. How about pull the spark plugs, use a bore scope (not sure if you can rent one vs buying one), and have a look inside, and at least that way you can assess you current ST‘s engine condition.Something else to consider.
I know of one other situation where an ST1100 had a water pump failure, the bike had approximately 250 000 miles on it when the water pump bearing seized, leading to the derailment of the timing belt, which in turn lead to the valve timing going out. The upshot was sixteen bent valves, a couple of broken valve guides and a set of pistons with virtually not a mark on them.
Like you the owner had a spare engine, previously purchased for it's gearbox, so simply used the heads (and water pump) from the spare engine to replace the damaged ones. Last I heard of that bike it was running in excess of 285 000 miles so I guess it was a success.
I only offer this as an example of course and your damage situation may be very different, but if it is possible it might entail far less work.
Do you have a motorcycle lift like one of these?From what I can find, the engine weighs a little north of 300 lbs according to those that have done it.
I've got some time before I can do it so I am researching it ahead of time.
It comes out the left side per the manual so I am figuring a furniture dolly blocked up should work to move it onto.
That's a interesting 'widget', the price is not too bad, and they supposedly have one locally.Do you have a motorcycle lift like one of these?

Thanks for that information. I guess I will have to wander over and take a look see (and hopefully catch a coupon along the way to get a better discount!).I have one of those - totally worth the money but I find the ram won't stay extended for any length of time, so plan to use the safety catches or something like wood blocks for support. It also works great as a lift to slide a double oven in and out of a wall.
I'm not sure how you'd keep an engine from falling off once free from the frame, though. Straps and some sort of cradle?
Phil, I have one on these lifts, if you need to borrow one, instead of buying. I also have an engine hoist Available.Thanks for that information. I guess I will have to wander over and take a look see (and hopefully catch a coupon along the way to get a better discount!).
John - That would be wonderful as I hope I won't need it again any time soon!Phil, I have one on these lifts, if you need to borrow one, instead of buying. I also have an engine hoist Available.

I had one of these from HF. It didnt hold up well. Spend a few more $ and opt for the aluminum upgraded version.Do you have a motorcycle lift like one of these?

You will be able to raise it up to the motor, block it if needed, and then lower it out of the frame after the sub comes off. Wheel it out of the way. When you put the replacement motor in, you can raise and lower it just enough to get the bolts through everything.
Nope - donor bike has already been stripped of a lot of stuff.Might be easier to move everything else to donor bike?????
NashCat has graciously volunteered the use of his unit, an engine hoist, and an extra set of hands when I get ready.I had one of these from HF. It didnt hold up well. Spend a few more $ and opt for the aluminum upgraded version.
