Help with 94 Sportsman 400

Hi all,

Ill apologize for the million questions. Recently I purchased a 94 sportsman 400. I was told the engine was fresh. (Its was freshly Junk) I sent the cyl out to get bored which is on its way back. however, digging a little deeper, I see its has several issues so Im going to pull the motor out completely out and do the bearings and seals. ok, so I see on the right case half it appears its missing some kind of plug or dipstick for the countershaft fill? where can I find one? or can I make something to put there? Any additional info on this part? Besides ebay, is there a good place to get a decent deal on the countershaft/waterpump bearings and seals? any tips tricks for this thing would be great. I want this to be a reliable machine for the wife. I was sold an old girl in need of some love..well lots of love. Thanks in advance. J..
