thought my water pump had a leak so ordered a new one. installed it and it leaked, or at least I thought that until finding that it leaks from this little drain hole under the pump.

everytime I rev my engine it pours out of the hole... is this normal?

also sorry about grammar.. i'm typing this from my phone.

The outer water pump seal. Change both while you are in there (inner is to keep oil from goin into the coolant/vice versa, outer to keep coolant from draining out the weep hole)

Click to expand...

Drain hole or weep hole?

Drain hole would imply your drain plug seal is leaking ( if there is one on your bike).

Weep hole, which is what I think you are meaning, would imply the shaft seal or shaft is shot, and allowing it to leak. Quite possibly the bearings are done as well.

When you replace the seals you should inspect the shaft and the bearings. If the shaft has wear grooves on it, you should replace the shaft also. The little hole under the pump is there to tell you when the seals are leaking.

As above but some honda's also have tell tale holes for things like water gallery o'rings, hope that is not the case for you though as its a engine split. Its probably just the water pump tell tale hole.
