I just recently put a roland sands air filter on my bike.I was just curious about riding in the rain.I bought the slip over rain cover but how much rain is to much.
I 've been runing with no cover for about 2 years. for the most part, no problems. BUT, I keep the stock cover in one of my side bags becuase in pouring as rain, you def need it.
I've been caught in some Monsoon type weather with no ill effects. I reoil at the first opportunity. Also, when I wash the bike, I cover the A/C with a plastic bag. The soap tends to leach the oil out of the filter if I don't.
