I am almost done with my bike however ,I can't seem to get it running at a good idle speed. I do not have my tach cable hooked up yet but it isounds like 5/6k rpm. I am running pods with the h pipe between the pods and the carbs. Carbs have been cleaned (3 times). I am running a custom 2 into 1 exhaust with almost open pipes. I have adjusted the air screw to see if that would help, had no effect. I have decided after much reading on this site that I need to adjust my jets. I have already found main jets for them but I am having trouble finding the pilots on mikes. I have not purchased anything as of yet according to the forums tech center I need to go up 3 sizes in the main jet and one in the pilot. 1979 xs 400. I'm not sure what kind it is.
