The first year EFI will probably go over just fine. I have not heard a lot of issues with the 700 raptor EFIs. But I think the longer you hold you, the better it will be. I think eventually you will just be able to download software and USB cable it to the bike to tune the thing. First few years probably all the software and hardware will be proprietary stuff which equals $$$ to play with. If they have it something like the GasGas where you get all the software and updates with the bike, that would be best. then you can tune at will for free at home or the track. it will be interesting to see what comes down the pipeline.
