Got an s&s super e on a mostly stock 74inch cone shovel. .68 .295 jets, bike starts fine etc. but when you get highr up in the rpms it seems fuel starved. Checkd for intake leaks, timing is good no loose wires etc. is it possibl the tank may not be venting correctly at w.o ? Got one of those tiny screw in caps with a small hole that you can hear hiss from time to time when moving it around..thoughtz or opinionz..bigger jet needed ?
