A while ago I replaced the seals in the water pump because coolant was pissing out of the weer hole even when the bike was hot...and after 2 hours of work and a forced oil change, with 5 hours of riding afterwards....still does this.....any Ideas?

Quite often, the water pump shaft itself will develop grooves in it, and will need to be replaced. Did you check the shaft for wear?

Just an off hand question could you have pinched the seal when you reinstalled? I did. :ride: I also had a "forced oil change". :devil: The next time I laid the bike on it's side to save the one hour old oil change. :banghead:
