I have noticed some members state the new Cubs use a bit more fuel than maybe they should. I have also noticed the inside of the exhaust pipe on my 2554 being a bit black with what seems to be an overly rich air/fuel mixture. Anyone lean their settings out?
I know the penalties for messing with such but I also have jetted a lot of dirt bikes for use at altitude in Colorado so I may just be the guinea pig here.
Another item that makes me think they are jetted and set too rich is the fact they can be taken off choke so quickly upon starting.
I also realize being air-cooled a rich mixture helps keep temps down.
Let the verbage commence
