Common YZ250 Rust Spots

Hello fellow “Thumperatalkers”, I have a question in regards to rust on my YZ250. I had left my bike out in the rain for a couple days about a month ago, and I am still concerned. I have done a general look around the bike and have only seen a small amount of rust on the radiator cap. Are there any other things on the bike that are prone to rust? Also, I pulled the jug to inspect the piston yesterday. There was no indication of rust on it or in the crank. Should I still split the cases to ensure that there isn’t any rust on the bearings or on the sides of the crank? Also, how do I check external bearings such as those in the linkage or wheels for rust. Do I need to pull them apart, or is there an easier way? Sorry for the long post. Thanks!

* I just wanted to add that if there is any rust, it would be noticeable because it has been a month since the bike was exposed to water. *
