    Working on getting my Centauro road worthy again. Lubricating the swing arm is on the list of to-do's.
    Advice on rear drive and swingarm removal appreciated.

    I may be the last person on earth to not see this as an obvious procedure.

    Thank you,
    Kurt

    My plug porcelains on my 1100 Carby Sport when removed are brown & clean on one side & black & rich on the other side. Have 35k miles on the clock & she runs great & gets around 45mpg on a 200 mile trip (70 -80mph cruise in 4th gear).
    Bike is ex USA & Iruns quiet restrictive cans (small outlets)
    Comments aprecitated - fuelling or exhaust flow?

    Fueling: Carb Balance and/or valves.

    Mmmmmm thanks.
    Had trouble setting the carbs balance last maintenance check but it runs smooth & responsive.
    Had also Checked the carb slides & some wear is evident, may have to look for new replacements.
    Will go & set tappets, do a compression check & see what I get.

    it'll run smooth out of balance, but the lean side will run hot and the rich side cool(er). I've gotten decent milage with throttle bodies very off balance but I did get oil temp faults when idling. Generally you'll be down on horse power milage will be a little down and it's hard on the valves.

    Thanks for that - agreed, I dont want it running lean & doing valve/ engine damage.
    Has plenty of power, runs smooth no hesitation etc. & idles nice
    Have just re- set tappetts & inspected tops of pistons visyally by light & all looks good.
    Will raise the needles a notch, re balance & see how she goes.

    The start of my thread may have been a bit misleading.
    Each spark plug is coated black (i.e. rich) on one, and is clean (dark brown) on the opossite side, & the interface includes the outside electrode.
    I will mark the plugs & check their orientation when tightened, then take for a ride & check again before I reconsider my options.

    Sorry, I just saw this. That is not unusual, and I would not worry about it if it runs fine. That is fairly common on older 2 valve motors.
    If you are curious, mark the plug orientation before you pull it. I would mark where the intake side is. Then pull the plug and you can see which side is which. I forget which is which, but I reckon you will see that both plugs show the same orientation of the dark side relative to the intake valve.

    Thanks GuzziMoto, you were correct.
    I just put some free flow Megaphones on & the first thing I notice is she starts up instantly from cold & can now be blipped with the throttle whilst lettingthe choke off; whereas b4 she would stutter & die & there was no way you could turn the choke off until it had warmed sufficiently to the revs came up.
    Overall it appears to have significantly improved the overall smoothness in the lower revs, so Now I will give her a good 200mile run & assess overall running characteristics.
    I'm sure the US mufflers (small outlet & very baffled) did not let her "breath", despite my drilling holes around the main exhaust outlets.
    The big plus - Sounds like a Guzzi should !
