Water pump seals

Just got of the phone after speaking to my dealer regarding my 2002 520 . We were just having a general conversation regarding the bike and he said to keep an eye on the water pump weeping water out of the weep hole . He said that they have had a bad batch of seals on the 2002 models and that they have had to change 10% of the seals .Has anyone had this problem or heard of it.I also asked about the cams bearings and he said they personaly have not had any problems but other dealers have. I get on well with my dealer so I'd say there must be some truth in this.

Can anybody confirm these comments.

I can't confirm it but I find it very interesting. One of the big pluses for '02 was a redesigned WP seal so it's the last thing I expected to hear about them. My buddy has an '02 400EXC. No problems so far.
