I got an 01 warrior and sometimes when i start it with choke, gray and white smoke comes out for like 5 sec or so, then it doesnt smoke at all. It doesnt burn any oil either. I just started it to move it next to the hose to wash it. No smoke. Then after I washed it, I started it and gray/white smoke came out for 5 sec again. Im thinking water is getting into carb? But from where?

 

If you were getting water into the carb, it wouldn't run very good, if at all. More than likely it's the early signs of needing a top end rebuild.
