As a brand new owner of an 02 wr 426 I was wondering if anyone else has had this issue. I have noticed that when I start my bike there is a very slight coolant leak coming from the water pump cover. It's just a drop or two and actually seems to go away when the bike heats up and everything expands. Has anyone else had this issue and if so what's the fix? I figure just a gasket or O-ring or whatever seal it uses. Any advice would be appreciated.

You need to change out the water pump shaft and seals. The part numbers for the 450 are in the FAQ. Cross reference them to see if they match...SC
