I am getting ready to get a 5 port. So use P3 plugs and I have a JP-3 now will that be good in a truggy? Soon I wil be going to a buggy and then I will need a different pipe correct? When is the most practical time to swap the rear bearing to the TKO? Where do you get the TKO bearings and why wouldnt you switch both? And is my choice on the 5 port the best for what I am going to be doing with it? It will be for truggy use at the most 2 months of saturday races. Sorry for the 20 Questions.
