Fuel leak in new-to-me XS11S

[XS1100_OEM4ME]

+1 Natemoen, You might as well get used to and good at a complet rebuild / cleaning of these carbs, not that hard and plenty of advice on here with step by step instruction The #1 thing I have found that effects the way these run is how clean and well adjusted the carbs are. You dont need to buy parts (unless some are damaged) I have even reused the gaskets three or more times when in good condition Just make sure "ALL" the ports, jets and emulsion tubes are clean and clear and make sure that the fuel that flows to them is clean and filtered (mine runs through the tank screens, then through two in line filters, then new needle valve screens) sounds like over kill but one pice of crap can make a needle valve stick open and flood the oil with gas Also make sure the float hight is "exact" and the stop for the float opening is set. If you get these parts right, you will have headed off many nightmares of trobble shooting
