'99 GL1500. I maintain it well and it runs great. There's a chance Momma and I will be repeating a trip from the Seattle area to Jacksonville, Florida this year. There are no symptoms of a bad pump but the bike now has about 112,000 miles on it and the trip will probably be 6-7,000 miles and I don't want to be screwing with a water pump in the woods somewhere. So do you think the water pump is nearing its end? Is there an easy way to check? How hard is it to replace? Any help appreciated.
