I am with PCS on this, and I've been saying it for a long time as well. Someone just needs to nut up and actually give it a try. As soon as one person does it and figures it all out, or most of it, then a second person will. Then a third, fourth, so on and so forth. After the first few people, majority of the kinks will be worked out.
If I weren't broke I would give it a try on my 250. Just because it's different, mainly. But I'm broke, and know the building an EFI set up will make me even more broke.
