After four months of layup, the bike in many, many pieces ( replaced tach, gearbox rebuild, swingarm bushes & Keigler collars mod, fork seals, valve seals/spings, tank de-rusting, oil pressure gauge added, rear frame hoop de-drooped), finally had everything back together today in hopes of a first ride. She fired up on second kick. Oil pressure up 40-60 range on new gauge with cold oil. Idling pretty well. After a minute or two noted oil flowing from rocker spindle cover, then noted a second cover with same issue. Bolt torque snugged a bit but failed to stem flow. I'd attempted to cobble the gaskets out of gasket making material and recalled if was a bit hard to get then trimmed/holed as needed. So that's most likely the issue. Did use some aviation type flange sealant (the black molasses type, not a silicone rubber) on these too. Oh well, live and learn. Need to order gaskets. Consolation prize was to hop on the Bonneville and ride her out to the Wigan Pier British chip shop in Squamish, some 80 km north of where I live.
