First you need to decide on a riding style and stick with it. It sounds like you are concerned about speed so you want big pipes, got vforce 3's, but you want to keep your stock carbs? That's not real good. If you trail ride get some good reeds for your stock cages, sell the vforce , buy some pt mids and your stock carbs will be fine. The one thing I have learned from owning these fucking machines is that you cant have one that is good at everything, thats why I now have four of them.I just dont have one thats good for anything.
