I installed the r-0990 on my 2012 250R with a dynojet stage 3 jet kit, air box gone, and a yoshi slipon exhaust. What do you guys use in the rain? cant figure out where or which one to purchase, K&N says they are avail but not from them, you guys got a brand or part number, thanks:eek:

I don't use anything. I have had it get wet twice and the bike bogs badly. Both times were down pour conditions and the bike was parked. I ride in light rain fairly often and have never had a problem, just mainly in down pours when the bike is not covered. If you use a good filter oil it should help with water retention as well.
