Duninshee Posted September 29, 2004 Report Share Posted September 29, 2004 The jugs just got an aggressive dune port job. My question is, Do I need to rejet the carbs? I am runing 280s mains and stock pilots. Needle is in the middle. I ride 4500 feet above sea level. I also just changed to 17cc domes.

Big Blue Posted September 29, 2004 Report Share Posted September 29, 2004 yes i would jet up quite a bit, not sure how much due to your elevation. Quote Link to comment Share on other sites More sharing options...
sredish Posted September 29, 2004 Report Share Posted September 29, 2004 The jugs just got an aggressive dune port job. My question is, Do I need to rejet the carbs? Without a doubt. You'll be flowing much much more air which means you'll be needing more fuel as well. All port jobs flow a little different, so we can't really tell you where to begin, but I'd go to 350s and start there, or maybe 370s. Definitely start rich and see what happens. Let us know where you end up as well. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted September 29, 2004 Report Share Posted September 29, 2004 If it's an agressive port job I'd start right where sredish said. Maybe even a 390. I've had to run 390's on a ported 350 before. Quote Link to comment Share on other sites More sharing options...
