I'd pay someone to split the cases and then get your hands on a manual and DIY. The key here is to be patient and research every single piece that you touch before you install it. That way, even if you don't know a single thing about engine building, you can still do it properly. Patience will get it right.
We have a guy in our shop that's impatient and refuses to take advice. As a result, he has taken a perfectly fine 636 Ninja, blown it up, and turned it into a rattling, blubbering, high idling, oil leaking, slow pile of junk. You'd think that being surrounded by a bunch of mechanics with over 90 years of combined experience and 4/5 of us certified Honda powersports techs that he'd have something that could keep up with the MotoGP guys. However, his lack of research time, impatience, and excessive pride have cost him quite a bit of money and he still doesn't have it right.
I say that to say this: The information is available to you. If you don't take advantage of it, the fault is solely yours. Any question you have will be answered.
