So i had the reeds out of my 93 yz 125 and noticed some junk in the intake and decided to flush it out so i poured a bit of mixed fuel in the bottom end to find that it all drained out the mag side behind the cover. i pulled the cover, fly wheel and stator to find that the crank seal was barley in there. with a little touch the thing feel right out! the seal it seal looked pretty good with the little spring still there so i pressed it back it and put it all back together. is the correct way to install a crank seal is to split the cases or am i all set the way i did it? i was think about buying a new seal for both sides just to be safe? any input?
