Ok here's my story. I have an 03 yz250. I went riding over the weekend and it just rained the day before. My bike ran strong when left the house. After a while it started losing power then it would be fine again. It also stalled on me a couple of times. I took it back and changed the plug in it. It seemed pretty wet so maybe it was just fouled. Iput a new plug in and it seemed to run fine and then beleive it or not it happened again. I not really sure whats happening because i havent fouled a plug in sooo long and it happened twice in one day! :think: I run it at 40:1. im pretty sure its not the gas thats the prob. My airfilter was fine not clogged or anything. Is it possible that maybe somehow water got in the engine? I dont know. Anyone got any ideas? Thanks for reading
