Depends on the kind of parts you're looking to start in. If you wanna run the parts for the local market ****, best of luck because you're gonna have a hell of a competition. No good if you ask me.
I'd suggest you start running (if you're in for it) the japs parts for all the motorcycles that we can't find parts for.
E.g. All the classic hondas suzukis, kawasakis and yamahas.
Plus you can make a lot of money importing parts for all these super bikes that we have on road now. as they eventually end up in a junk yard somewhere due to the lack of access to the parts. That is why every superbike owner usually get rid of their bikes after they've had a good 2 year run.
Hope this helps.
