Raced two classes this weekend and noticed this while washing the bike today. Bike has plenty of coolant and the high was 65 degrees this weekend, so I have a hard time believing it over heated. Bad water pump seal? Bike has 166 hours. Bone stock.
This is bc even with new seals, the old shaft could have a very small groove in the shaft from the old seals. New seals may last a ride but then it leaks again,,,post results- J
While you're in there, if upgrading your water pump to a Boyesen setup/other was on the bucket list, now's a good time to git 'er done.

Why would you not have a service manual? It's your bike, your investment and you should invest in it. The cost of the manual is less than the cost of doing this repair on your bike.

I was going to comment on the assembly lube --- and that I would put a lot, too --- so I think it's a "wait and see game" and you actually may have already solved the problem.
