suzuki ts250 crankcase question

Post by dollydog »

looking at the diagram below, around the left crank seal are 3 holes [only 2 visible on the drawing, but there are 3 at 120 degrees apart] that are bunged with some non magnetic metal and look like little black plugs. does anybody know what they are actually for? only reason i'm asking is because after taking my stator off i noticed that one of them was slightly weeping 2 stroke oil, so obviously if oil can come out, then air can be sucked in. any help greatly appreciated.
cheers, dd.

oops, sorry dor, i missed your post somehow :oops:
yes, they are the ones. the only other thing i could think of, if they are threaded [not at the mo], they are used for a different stator? at the moment they just seem pretty pointless :) i have in my collection of odds and ends a stator with 3 holes in it that line up perfectly with the 3 black dots. unfortunately i haven't got a clue what it's off. anyway, thanks for the reply. i suppose the only people that would know for sure are suzuki techs.
cheers, dd.
