Hello folks any advice appreciated. I rebuilt the fuel tap on my gs850 with rebuild kit. The tap now hardly flows on prime, on, or reserve and engine wont start but overflows into engine overnight and leaks with oil from somewhere onto floor. Slight amount of petrol in oil. Dropped the oil and replaced but not sure what to do now because already rebuilt tap. The bike has just been recommisioned after sitting for a few years. I have cleaned the carbs. What to check or do next? Thanks
