classic motorcycle forum

hello everyone, i just picked up a 1980 honda xl125s for free, but it needs some work. Hence joining this forum. I looked on the internet and found only 2 places that sold OEM parts, and nothing for aftermarket. All this bike needs is the usual general maint stuff like all fluids/filters/tires. The big stuff is front shock seals, new gas tank. Thats about it. I can only find OEM replacement gas tanks for $211, which is way to much for me. Anyone able to help me out here? Also looking for aftermarket stuff like pegs, exhaust, controls, just little stuff.

thanks guys! pictures soon!
