    On my XS1100 I did remove the Octo system, but then you have to play around with the best way to get the fuel line eight straight down from the petcock or over to the other set of carbs. I am guessing your carbs are like mine and there are two sets of two? There is no sharing of the fuel between 1,2 and 3,4 on my bike. So two fuel petcocks, one for each bank.

    My XS1100 has double down tube petcocks...I don't think yours does? Not that I can see them in your pic above.

    Rebuild the octy fuel valve, its a safety feature that shuts off gas if the bike falls down. You don't want gas all around you in an accident. Diaphrams are easily available to repair it.
    I use Motion Pro 1/4 black fuel lines on both my XS and XJ11. Its a little pricy but lasts a long time. So far my XS11 is going on 8 years with them. The XJ11 got them 3 years ago. I found that regular 1/4 fuel line at the parts store is too thick and does not bend easily. You will need about 6 feet of line to replace all them.
    The handle on the petcock is the indicator as to what it does. Whatever it covers is what it does, On,off, reserve or prime. There is a right and left petcock don't get the parts mixed up when rebuilding.
    A rebuild kit for both petcocks and octy valve is about 30$.

    When rebuilding my octopus, I ended up crossing the feeds from the petcock to the far side of the bike, after the 'T'. This allowed me room to put in-line fuel filters in without much fuss.

    I was thinking of getting some aftermarket petcocks, run one fuel line between them. Drop the fuel line to the carbs with "T's" at each carb fuel intake. The stock petcocks don't leave much room for fuel lines or clamps.

    I run T 4 or 5 in all my bikes, have never had a issue. That is a great cheap oil.

    Just don't put all 4 quarts in. Capacity with the filter change is just a tad shy of 4 quarts.

    If it's the same 20w50 valvoline that I'm running, the best price I have found in my area is $4.99 a quart and farm n fleet. It gets over $7 at any auto parts stores that carry it in my area. Worth the 2p minutes to drive to farm n fleet over the less than 5 to advance auto parts
