1. jetting a single carb is just like jetting 2. what size carb do you have.
2. actually alot of people say that the single carb setup sucks, so you may wanna think about going back to 2 carbs especially if you want more top end. the best mod is porting but if you have stock exhaust, youll see a big gain just from getting some pipes.
an adjustable timing plate set to +4 and a cool head are good mods also. but the question as always is what type of riding do you do?
3. as far as anything you need to know, youll find that out and some things you dont wanna know on this site. :biggrin:
