Bike sat a couple years after I stopped commuting on it. Ran fine up to about 90mph. Was always a little hard to start cold, especially the longer I didn’t ride it. Fuel started to gel. Cleaned the carb and put in fresh treated ethanol-free fuel. Didn’t help. Had to spray fuel in the carb. Hard to keep running, at best would eventually die at idle and wouldn’t rev enough to ride away. Found the jets to be 45/165. Considering the Buell Pro Series intake and V&H exhaust, this should be lean, so I got 48/175 jets, sanded some washers down to 0.050” to shim the needle up, and adjusted the screw to 3 turns out (from about 1.5). Added a large Wix filter to the fuel line. This essentially changed nothing. Still have to spray a lot of fuel to start and it won’t hardly rev. Fuel bowl is filling fine..
IDEAS?
