How did you use the seafoam? I have some and don't know to use it. I sank mine last sunday and am changing the oil and seen your post and am wondering if it helps.actually it only took 4 oil changes.. along with some seafoam for insurance. There wasnt all that much water in the oil. i think the snorkel actually helped me.. the air box hardly had any water in it. But when it flipped upside down i think water went through that vent at the top of the airbox.. This is one strong bike..
