95 XR100 -- Need parts

Where have you been looking? That bike is very common, and parts are not difficult to find. Virtually any Honda dealer will have OEM parts, and aftermarket suppliers should have most parts you could need available as well. I'm not quite certain why you can't find anything, my guess is you haven't found the right sources yet. Dennis Kirk, Bike Bandit, Service Honda and others all have many parts available online, which should give you a start to your search.
