Hello,
Sorry for the Noobness. I don't have much experience with dual carb motorcycles (only dirts bike when younger). This is my first motorcycle since then. Any how bought a 1980 XS650 for a project in the evenings. When I purchased it it ran but was rough. I pulled the carbs and cleaned them. Now only one cylinder fires and fuel comes out exhaust of dead side, unless i shut of the petcock. A couples seconds after I cut off the fuel to the carbs the second cylinder picks up and the motor revs to about 4000. I am at a loss on what to do. Also the factory petcock was replaced with an on/off/reserve and the vacuum lines at carb boots were plugged. Replaced spark plugs and spark looks good. Also has cone filters instead of airbox.
Here is my bike so far
