I'm finally moving over to two carbs to see what I've been missing. Using the oem 932s that the bike came with, but renewed jets, needles, seals. One bowl banjo is metal and seals well with gaskets. Other is plastic and I'm unsure if gasket needed between banjo and bowl, as I do have the plastic screen filter there also. Got the choke blanking screws to eliminate choke cabling. I'm following Bushman tuning guide for initial settings. Wish me luck!
