Hey guys, Have just bought a ktm 300exc 2006 mdl, When i first got the bike i drained all the fluid and replaced them without a drama, After 4 rides i changed gearbox oil and found my problem, attached to the magnetic sump plug was a small (6mm) bolt with a hecs head (allan key) flush head. Dont know what it is? where it came from? or what to do to fix it? Help please..
