Oh. The "P" is a little separated from the "RI" so I figured the "P" was a separate setting for "Park", to be used while you are inside the pub getting a beer. My valve has a "P - RI", a "RES", and an "ON". I guess there isn't an "OFF"? Should you put the valve at "P - RI" to start the bike? What do you put it on when the bike is going to be sitting for a while? Sorry for the unthinkably niave nature of my questions. As you can see I have no pride. Thanks muzza - I think she is almost ready to start!
