Went out for a quick ride last night and went to start my 00 Yamaha sxr 500 and it wouldn't go. So I pulled gas line off my carb and sucked antifreeze out! How does this happen? A blown headgasket wouldn't do it I don't think

FYI..........A lot of the yami's have heated carbs. They come in handy on those cold cold mornings. Specially if there's lots of light fluffly snow dust. Cold air, humidity, etc. all have an effect on the carbs freezing up. Some people turn them on for the first 15 minutes and then shut the valve. You can experiment with yours, and find the best performance for certain conditions. You won't hurt or break anything if you close the valve.
