I just recently did this with my 750 k8. Its pretty simple, or at least mine was. I bought stock ears, turn signals, headlamp bucket and light, as well as those rubber rigs that go at the top and bottom of the fork ear tubs between the fork tube and the ears tube. The wiring harness on my simply unplugged from all the connections in the wiring harness. No splicing, no taping and just the same type of connectors all over the bike. Everything else plugged right back in to all the new stuff with not problems.
Another thing I found was that the front brake hose, the metal one coming out of the caliper had been changed and so had the routing of the brake hose up to the MC. The NOS metal tube is pretty easy to find and made the hose hit all the spots it was suppose to originally.
I'm going for a completely stock look, and have managed to find all the stock front end parts mostly off ebay and this forum.
