I've posted links to this guy's work before, but this 872cc project on a 748R (Guy are you reading this??) is exceptional in my opinion. What impresses me about this guy is the level of detail he goes to with his tuning efforts and his write-ups. I mean 130 RWHP from a 748 is hugely impressive!
It's a good read (well for techies anyway).
