Main Jet – 260 Pilot jet – 40 Needle clip on second slot up from the bottom. Needle jet (emulsion tube) – Q-8 Air screw 1 3/4 turns out.

Air screw 1 3/4 turns out. September 10, 2017 at 3:48 pm #3465 Chris RogersParticipant Will be interesting to see the difference between the 34mm and 32mm. Dan barford reckoned he had better results with the 32mm. November 14, 2017 at 9:48 am #3531 mongno1Participant Does anyone know any other bikes that either of these carbs are fitted to as standard ?
