I have PC Duals and K&N Filter with Dynojet Jet Kit. The kit only tells me to run 124front and 128rear jets for a high flowing muffler. Im not sure they are using a single pipe or duals when they tell us to use these jets. Dont the duals flow better and thus need a different jet? Since I am running a K&N I went up on the jetting to 126front and 130rear, is this ok? My plugs are dark around the insulator and have a greyish ring around the electrode, normal??
Also what is everyone else running at 1,000 to 2,000 feet with duals and K&N as far as jetting? Should I switch out to the Keihein Jets? Thanks for the help
