if yu really want to know there is a trans oil out there , not sure of the brand, my local independent bike shop sells it, that has a color in it, red im thinking. he sells motor,primary, and trans oil in 3 different colors. when i asked him wtf he said if a customer calls me saying his bike is pukeing sumpin, i just ask him what color and i know what kind of job i got comeing in.yu might try looking for sum of that.or yu can clean the bike up really with a pressure washer then when dry spray the suspect areas with spray starch after its dry. the leak will be pretty evident if yu look close.
