johnautobus Posted October 5, 2004 Report Share Posted October 5, 2004 My stock cdi box went south so I bought a dyna fs box. I installed it and banshee runs. Problem is that motor will not idle and misfires at high rpm. Could the new cdi box be letting the motor rev higher? The directions say to rejet to bigger. I went up three sizes and back to 1 bigger and I still have the misfire at wide open. I borrowed a stock cdi box and it idles good but motor misfires off low rpm. Higher rpm seems better. does any have had experience with changing over to dyna.. What does a person have to do to make motor run right. I think the idea is good to change timing but I am growing tired that banshee would perform. Help would be appreciated. Quote Link to comment Share on other sites More sharing options...
