I need some advice.

I sunk my bike over the weekend. I had a little too much liquid courage and tried to cross a pond that I shouldn't have.

My snorkel barely dipped under the water and as soon as it did, I shut the bike off. We pulled it up the side of the pond and i stood it on it's rear end to try to drain any water out of the exhaust and air box. I got it to fire and rode it back to the camp, but if I let off the throttle, it would kill.

When I got home, I took the carb and air box out and cleaned them really good. I drained the oil and let the bike sit for almost two days. The oil didn't appear to be milky, but I am going to change it twice more to be sure.

I tried starting and running it tonight to circulate the oil through the motor, but it still will not run at idle. When I gas it, I get a lot of backfiring and what appears to be gray smoke. I ran it for about three min, before it killed, but now it will not start at all!

Sorry for the long post, but I need help and want to get all the facts out.

The one good thing you have going for you is that those single cylinder/air cooled yamaha motors are truly hard to kill. Follow the instructions Phreebsd linked you to and you should be able to get her going.

I still can't get the bike to idle. If I hold the throttle open, it will run. Even when it runs, it is popping like crazy through the exhaust. It smells like it's real rich. The fumes will actually burn your eyes. I need to get back into it tomorrow.

I did empty the gas tank. I had to waste almost a full tank of fuel, but better safe than sorry. I let the tank sit open over night to let anything remaining evaporate.

If anyone has any ideas, let me know!
