today i was trying to find out what was wrong with the rear brake on my ytm 200 and when i opened the case for it up, i found a *Edited**Edited**Edited**Edited* load of greasey sludge, my brother told me it was from dirt and dust and such collecting, but i thought it may be some kind of lubricant for the break,....we both know nothing about machines like this so i know someone on here could help me out.
thanx
