I know this is a heavily covered issue but I dont have much access to the internet right and was hoping for an answer by tomorrow. It is on a '77 XS650 (my dad's bike). It had an issue and was draining gas out of what looked to be the float bowl so I swapped his carbs out for my old ones ('79 XS650) today and took it for a spin. It seem to work great. I then let him go for a ride but he accidently kicked it into 1st from neutral without the clutch and killed it (he was pretty excited and just didnt realize he didnt have the clutch in haha). When we tried to get it started again it was draining gas through the air filter. What could cause this? I mean it ran parfect for me then killed it then carb is free flowing? I mean this may have been the problem before as when I removed the filters to replace the carbs there was some gas in them as well. Any help would be awesome. Thanks a lot guys.
