is a stock 4 clutch the same as a 600 ? what kind of fuel do you recommend? highest octane available? or does it matter, ive heard it both way for other sleds. how bout if i have to put coolant in it? what kind, 50/50 or straight up or some special kind from nasa? i dont like buying nice things cause i get all paranoid. i like things u can have fun on and not have a heart attack if u sit on the seat wrong and make a wrinkle. so i will probably be asking you guys a lot of dumb questions. be prepared!
