    Reserve petcock without stub pipe is supposed to be on the left hand side on a P11. Commandos have them on the right, I believe.

    Or at least that is where the reserve stickers are on my bikes.

    Can they be switched from side to side for sake of consistency between bikes.

    What do you prefer, having the reserve on left or right hand side?

    I have mine on the right hand or as in the UK called the (offside). This is preferential to me, being right handed.
    Only the rivet counters will know, if you choose the opposite side to as it left the factory.

    I just noticed the fuel outlet bungs are not symmetrical. The right side on my P11A tank is way further outboard than the left. So when riding with the reserve off, the lever will be sticking out, as opposed to being tucked in towards the frame as was intended.

    Looks like I'm just going to leave reserve on the left hand side as per original. I will just need to remember that main is opposite Commando.

    All the old sons-of bitches fuel taps leak anyway. So when you sputter out of fuel open the other one but don't expect to get very far. Then, when they're both open and your still out of gas...push.

    Or go and buy some good ones and be done with it. It doesn't matter what bloody side you put them on unless your an OCD concourse nut.

    Nothing to stop you fitting a leakproof washer between the tap and the tank to make the taps easier to turn on.
    Also check that both taps have the SAME height inside the wire mesh, they could be different :!:

    I would think the reserve tap should go on the left side (mine is on my Commando). That way you can switch it on as you keep your right hand on the throttle sputtering down the road.

    My '66 Matchless G80CS scrambler had the same tank as the P11 and reserve was on the right. My '72 Commando is the same. I believe they switched sides for the reserve around when the steel tanks appeared in '73.

    My new reserve (left side) is perilously close to my p11 air cleaner. I need to order some type of elbow for it. Any suggestions?

    I trimmed away the air box plate causing interference, not much, maybe 1/2" x 1/4" half moon slice.
    An elbow or rather a 45 deg piece helps as well.
