Well, I'm glad I only have to watch. My first choice would be, like suggested, to make the LC4 more reliable. I've seen people do this. For a transplant I'd go with the F650 Classic motor. Dual carbs (in the rear), very tunable, reliable, good mileage and I see a lot of low mileage ones on CL. They still hold a good price, tho, so maybe a wrecked one. But in the long run, no matter what you put in that KTM frame, how is it going to be that much better than a KTM?
