oil leakage

[kxrider125]

i got a kx125 and when i rip for a while, the govener shaft boot spits oil. IT doesnt do it all the time and doesnt affect the bikes performance at all but i cant figure out what it is. i think its tranny oil but im not shure any one ever heard of any thing like that happening.

ok, if i am picturin it right, it is comin out of the sprocket right, if i am wrong just dont mind this, but if i im right, theres a little o-ring you have to replace, just pull out the shaft the sprockt is on , and replace the o-ring, and it quits leakin, tell me if im wrong
