Bit late but only just seen it. My Bantam has D14 engine with B175 head and runs fine on either B6ES or B7ES, Petroil mix on full synthetic 40:1

Hi,

mine is a Drayton 185cc running a standard B175 centre plug head with B7ES plug.  50:1 petrol oil mix using putoline.

PVL ignition set 1.1mm BTDC

main jet 120

pilot with 2 rings

105 needle jet

NO.3 slide

seems to work fine for me.

one thing you ll find for bantams is that no two are jetted the same. however buy a set of jets and much and i mean much time later you  can have a bike that runs as smooth as poured cream that ll pick up clean from stopped dead on a slope.. no big bang of power they were commuter bikes remember.. but enough to haul evenbig boned fellas around more than adequately.. mine is std b175 on pvl with drayton exhaust used 50:1 for last 5  years
