Well my mom's 2000 honda shadow latly has been having issues. Basically progressivly pouring black smoke(unburned gas) out of the exhaust, I have some mods on it such as intake, porting, cams, and exhaust.. I figured a jet fell out but the odd thing is I checked bolth cylinder plugs and bolth are covored in carbon(aka bolth are getting way too much gas). This is odd. So I inspected the carbs and all is well. Is there such thing as a fuel pump pumping too much? I figure the floats would eliminate this but thats all I can think... bolth getting too much gas simotaniously, out of nowhere. PS, this is also tested with all intake off to rule out air filter issues. Thanks-darren
