Great question. A reservoir does not “need” to be above the master cylinder. In theory, there should be zero air in the system so it doesn’t matter. I believe that it is usually placed above as precaution, so if air were to get into the system it might make its way up to the master cylinder.canyoncarver said:Is the reservoir lower than the master cylinder? Will that work right?
My reservoir is actually just about level, however the clear tygon hose loop is well above the master. If air were to get into the system, the highest point is that hose loop where it would be clearly visible.
I have a great motorcycle museum nearby, and I actually noticed several race bikes with a lower reservoir which made me consider the whole theory.
For an everyday rider just racking up miles between servicing, put the reservoir at the top.
