I couldn't find anything in the threadfest about this so I'm going to start a thread. Ok, so it's winter and the bike's not being ridden as much as it should. I pull the oil dipstick every time I go for a ride and have a look in there. The last few times I've noticed the milky residue ( ) that nobody wants to see building up around the neck of the oil tank and under the dipstick cap. The first time I noticed this I freaked out and thought that coolant somehow escaped into the oil so I changed the oil. There was nothing in the oil to prove that though, the oil was perfectly fine. Somehow moisture is getting inside the oil tank through the cap, the o-ring is fine so I am astounded as to how this is happening. There is a gap of air between the oil and the top of the neck and this is where it is happening. It's starting to worry me a little since I see a little rust even starting to form close to the threads at the neck. So, any ideas as to what is going on here? Has this happened to anybody else? I live in colorado and it's been snowing a lot lately so the moisture is in the air and I've ridden in wet/snowy conditions a few times but how the hell is it getting in there? Thanks.
