Quick fuel makes the billet 850 base plates with Teflon bushings ,sealed ,run around 150 ,curved bowl vent kit 20-50 ,secondary 50cc pump kit 20-50 ,build it from there . The demon is a good deal if its marine version ,those seem to have less intake noise than the choke horn versions for some reason .
