Originally, it was to the rear (intake side)..... The 500T's have one on both covers.... AS long as it's open to "breathe" out, you'll be fine......

Originally, there was a hose attached that simply curved down along the backbone to beneath the frame and "dumped" (open to air) any excess oil onto the roadway...
The hose length was more to prevent dirty air from being sucked in than anything else.
It should have no real effect on the engines running.....

The only thing I can think of by not having something attached is that you'll tend to have an oily mist exiting into the under-tank area around the carbs. It's not dangerous but will cause a little bit of an oily mess.

Most people just use the before mentioned length of hose, running down to the ground. Others I've seen, have used a short piece of hose with a little crankcase vent breather/filter. Almost like a mini K&N filter looking thing.. I'd stick with the hose myself. No filter to worry about plugging up, or cleaning.

i got a question on the 450. On my breather cover there was a plate in between the cam cover and the head. Is this plate necessary because i have slight oil leak around that area even with new gaskets installed. And if it is required....why?
