It got up to a toasty 40 degrees out yesterday so I decided to try to start my new to me 2003 WR450. With a little bit of coaxing she finally turned over. After a quick ride around the block I noticed a few drops of anti-freeze right were I started the bike. It looks like there is a factory predrilled hole underneath the water pump housing (which is on the kick starter side of the bike, the hose from the radiator connects to the housing, obviously). Has anyone else noticed this or has this issue? I'm not sure wheather the anti-freeze is coming from the predrilled hole or the seam of the housing. The hole has got to be there for a reason and it is only about 5 drops of anti-freeze.
