My EP90 having arrived, I have just poured some into the gearbox of my 1965 B40F, having drained off the old stuff last week. The capacity I believe is supposed to be 3/4 pint. Yet the oil was coming out of the level tube when I had put in less than half a pint. Seems a bit odd. The only two explanations which spring to mind are: 1) there was residual oil in the gearbox? But surely the drain plug is at the lowest point when the bike is on its centre stand?; or 2) the oil level tube is too short? Maybe I need to take it out again and measure it? Any advice would be appreciated. Phil.
