Oil Leak! Split the case???

[thing2_and_thing1]

I changed the oil last night in the kx100 and this morning I noticed a small oil spot. It appears to be leaking around the front sprocket. Do you have to split the case to get to this seal? :yikes:

no you will not. you can usually get them out pretty easily. there is usually a collar and o ring that slide off of the ouput shaft and the seal will be right there.
