Think about it and when you are ready make sure you get all the HP you want and do it one time. All the kits are reliable and run good on the street. You can go to 100 HP with pistons, heads and cams and pushrods. Going above that will require roller rockers. They are not cheap. And not sure what else since you have a carb. Its really not that expensive considering what some spend on their bikes. But if you are going to be a bear, be a grizzly.
