Everytime I start my XT125X it revs into space and I have checked for air leaks and replaced the boot that goes from the carb to the engine. I went to go check for an air leak on the left crank seal and there was a pool of oil in the stator cover, is that normal or it it the seal allowing oil into the cover? When I stand the bike up oil trickles out but I’m not sure if that’s the left over oil at the back of the stator cover. Please help!!!!
