big oil leak

Shift shaft seal ????

Hi DanielKDX125,

Is your KDX an SR model? Does it have oil injection? Do you have a metal gas tank?

If so, look under the engine... does it have a "D" shaped hole in front of the oil drain hole (on the case half seam)?

If so, wipe it and see if the oil is coming out of that hole.

If it's coming out of there, then you probably have a crank seal that is leaking.

The US version bikes do not have this hole, but the SR models do...
