It is widely believed that the miniceptor (500) was not prone to an oil starving situation. This has NOT prevented some people from installing the mods available, but I have not done it, and mine has over 25k miles, with nary an issue in sight.
The 750s did have this issue, and your date range is good enough.
Reliable? As with any inexpensive, older bike, you've got to accept doing some maintenance which might not have to be done on newer bikes.
There is a relatively good supply of 500 stuff on Ebay and in user forums, but I don't know about the 750 supply.
Hope that helped, and post if you've got more ?s. Drop me a PM for group-specific forums.
