Venting crankcase
Ok, I'm going to vent the crankcase to the atmosphere so I don't get oil back in throttle body and motor. Was wondering if any of you have done this on a softail and if so, where did you run the hose? Pics would be great! Thanks.

Usually when you are getting oil out of the breather you can fix this by only filling the oil tank to half way up on the dipstick. A lot of people also end up venting their breather back plate by drilling it and adding a small filter as opposed to venting their crank case. I don't think venting the crank case is necessary.
Here is a link that shows a vented breather with pics. Third post in the thread I believe.

Check out Mud's postings in the "DIY under fifty bux" thread in the Dyna section.
He's made up a couple of different breather sstups for his Dyna that should work just as well on a Softail's "B" motor.
Try looking on the last couple of pages first for his latest version.

I agree with Drew lowering the amount of oil in your tank helps.
But before I learnd this trick I vented my fatboy.
check the softail dirt cheap mods - homade breather kit about the twentieth post I provided pics.
