Lisa Epifano Hall, yea, I never get more than about 6000 miles out of my tires, but then again I change them yearly whether they've got tread life left or not. Too many heat cycles and they start getting hard which gets problematic when leaning the thing over.
Hmmm. $900 at 18K. I think that's probably around the same range that I pay for having service done on my bike. I'll have to check my records. But I rarely put that kind of mileage on unless I'm touring. My bike only has 92K on the clock.
I'm really surprised by the water pump. That is troubling.
I do admit the "technological monsters" that these bikes have become is a real turn off for me. It's the same with cars. With increased complexity and performance comes radically increased cost of ownership over the long term.
Were you running Marathon's or similar hard compound tires on the Gold Wing? What year Gold Wing?
What are you riding now?
