Thank you all for your comments.
So far I have not had any major issues with the 2002 GL1800. I do change my oil alot, change all the fluids annually, some more often, keep good tires on it, do all the maintenance items and I constantly check the bike over for loose nuts, bolts, and other things. I lubricate everything that moves. I have found over the years that if all the little things are caught early and taken care of that seldom are there major problems. When I take the bike apart to service it and all the plastic is off I always clean everything that is covered and wipe the frame down. It just seems to make a difference.
I have redone my front and rear suspension and I feel that has made a difference with the handling and performance as well.
I hope it has another 100,000 in it.......
