472 super cub BB CPI vs BB shearer (both inframes) and 35mm carbs vs 39 pwks


Recommended Posts

Was wondering which pipes would be better for my style of riding. I do alot of play/dune riding. I have the shearers on it now and it's peaky uptop but want a Lil more bottom end. but I'm still dialing it in. I have 472 sc/shearer bb if/39pwks/50pilot/168main/CEL needle clip. 30-50 degrees outside/sea level/ pump gas/ air-fuel screw 2 turns out does jetting sound right??

 

Also would 35pwks give it more bottom end than 39pwks?
