Try both and see which one you like. 650cc's is a good volume and change it maybe every 10-15 hours of use max and your engine and clutch will be happier. Most of use a 50/50 mix of distilled water and auto anti-freeze with good results. You don't need to bleed the system but it's good to check it after running a short time just to be sure you don't need to top it off. Fill the coolant to the bottom of the filler neck and if you over fill it a little expect a little to dribble out the overflow tube at first (not a problem).
