RE: Evo oil venting...lots...and lots...
Part of my winter maintenance is after I drain the oil I give the check ball a light tap to seat it good then fill it up with fresh oil run it and it's good for the year, before that It used to mark it's spot I work overseas and am gone for 5 weeks at a time so when I came home it would puke when first starting it up. now it doesn't

Would someone point me to a thread with more information about the check ball?
I've got a 93 Evo that's been pushed to 89". The breather/vent hose lets out oil by the droplet enough that the rear tire is oil after a couple miles, and lets about another 4 drops after I park the bike.

The check ball only prevents oil from filling up the crankcase when the engine is stopped. If your getting oil out of the breather after you increased the size of the engine then you probably didn't enlarge the timed breather hole, you can get the exact size and timing of this on the S&S website. Basicly you have to change the hole from a rough cast oval hole to a square hole, easier still is to just take the timed breather out and replace it with the S&S reed valve it works much better than the timed breather. I assume yours is any early 93 that is not a head breather. To covert it to a head breather TP makes some great rocker boxes that cures the problem but it's not a cheap fix. I would just try the reed valve first.

Well, I'm not sure how everyone else does it, but I upload my pictures somewhere (I use my own website/album) and then I get the URL of the image (The http:// location) and come here, and click on the yellow "Insert Picture"square icon. This pops up a window where I paste that URL of my image and then click ok. This inserts the picture into my post.
