I was reading Hondaman's 500/550 tips (yowza, thanks!) when a thought occurred to me. Advice was to change the oil pump after 20,000 miles. I have 35,000 on her so I start thinking about this. But wait! I don't have OEM gauges. For all I know it may actually have anywhere from 1,000 to 100,000. Is there anyway to determine how many miles this may have on it?
I'm not really interested in an actual figure but rather a range for preventative maintenance purposes. I suspect a thorough inspection would reveal the general condition and a 'To-do' list, but I'm a newbie who doesn't know what the heck I'm looking at. If I can see something is wrong, chances are it's already way beyond catastrophic.
Thanks.
