crank case breather

So I am in the process of restoring an 86 rebel i bought for $100 at the beginning of the summer. Its coming along, but I'm missing a lot of parts. the bike did not come with any of the stock air intake parts, only a pod filter. I wanted to use the pod filter, but I was concerned about the crankcrase breather. I'm trying not to buy the whole stock intake because that would be expensive.

Would it suffice to simply run a tube from the breather to the bottom of the bike? My only concerns about that is the breather may need the vacuum created by the air intake, and atmospheric pressure might not be great enough for it to breathe. The guy I bought it from planned to put a small pod filter over the crankcase breather, but I figured that would clog up and cause problems. Has anyone done this before or have any ideas?

Piston movement creates alternating pressure/vacuum. Leaving an open tube runs the risk of sucking in unfiltered air and grit directly into the crankcase. Have you tried looking for used parts on ebay, Jacks, etc.? Possibly there is a parts bike near you?

Keepin' all the left over parts. Gonna use 'em to build another bike!
