let me correct yself, the first things you shoudl do on ANY new car/truck/motorcycle etc.. is to get to checking over the basics..fluid levels, condition of ball joints, brakes, suspension and the overall health of the engine and trans. From there work on getting her bvack to at least OEM functioning form andafter performing those things ytou'll have learned enough from reading that you'll probably know the first performance things to do.. Hell, I don't even know the first "free" things on a GN/GNX, I bought one built to go low 10's, i just have to put it together,( but it helps io've been racing and building things with engines for over20 years at this point...saying that makes me feel old LOL ) thankfuly the trans, engine, suspension and all are new in it but there's still a lot of maintenance i'm finding that will need done once i'm finished assembling it.. but the basic principal in ANY engine is more air in and more air out = more HP (but you need the fuel system to support the air) and management to keep things in check once you pass a certain point,
