I don't know nearly as much as I'd like to about my carb ('95 XR600R). I went ride this morning and when I turned on the fuel, noticed a steady stream of gas running out of the overflow tubes from the bowl (?? the bottom part of the carb). I fiddled with the throttle for a minute and removed the drain bolt from the bowl. As soon as I turned the fuel on again, gas just poors out of the bottom. I rode the bike hard for hours last Saturday without any problems at all. It's been parked since. I'm planning on pulling the carb off tomorrow. Any help on what I should be looking for? Obviously something that should be closed is stuck open, but I'm not really sure where, or what I should be looking for. Thanks for all your advice!!
