I just got this bike my first ktm she´s vintage but still runs strong KTM 125 exc haha!! but first I was wondering how much gear oil that my 125 exc takes? and also I can not find parts for this bike for the life of me just eBay here and there ....I´m looking for either front and rear complete brake assemblies besides rear break lever, I believe this bike came with a flange for where the exhaust mounts to the head of the manifold and mine is a dyno port exhaust any suggestions to stop the black crap that is spitting outta there all over the place ? worst case I might just just have to buy a new pipe and silencer . thank you please help with parts if you can!!! and taking any advice
