As some of you know I have had intermediate oil leek into the crank where it would load up with transition oil burn it up and go away for a few, miles then load up again. I finally had enough. After talking to my dealer as what to look for I tore the clutch side case off to take a look-see. What did I see….just as my dealer thought the main seal was in backwards, hence the intermediate leek. Luckily the seal is only $24 so I replaced it an now no leek. So all you 250 and 300 owners check it out I may be the same as mine.
