To keep it simple, what are the best mods you can do to your bike and get the most out of it without having to go turbo or use nos (engine wise)? I was looking around and saw that people offered bore kits? I also noticed how much money they were.. Is that pretty much the best thing you can do? Also, for that much money, they don't seem worth it.. I guess if you ended up going turbo you would have to get that anyways right? Later down the road, I would like to get a turbo system but I don't want to just slap one on there for durability reasons. I want to make sure I build it up and make sure I have no problems when / if I do get one.
