I'm sure you could make "something" but would take some effort and appropriate material to make something good and reliable.
Buddy of mine is in the US for another week and going to carry it back. He's actually one of the 5 owners of the bike :)

A small amount of the oil vapor may be pushed out from blow by , but MOST of it is from 650cc of air displacement every time the piston goes up and down.

Like OnO said, get some bark busters(along with a new lever), problem solved! Some bark busters require you to cut the ball off the levers to work.



PBOB, There's not much "mist" by the time it gets to the air box. Just drops of oil. It would leave a small puddle of oil in the bottom of the box and start leaking out the drain tube. It was off the bike when I purchased it. I put it back on after about 6 months. No more air box mess!
Trackside shortie levers from Cyclegear for an XR250. You won't have to remove your balls.

That's why they call it a breather tube. There's something alive down in those cases.

This is what I need. Hard to tell from the photo. But it is a loop of plastic that wraps around the swing arm.

Ulyses made his out of nylon laminate, or something like a Derlin cutting board.

Might be something to keep in mind and probably easier to find a cutting board then a thick piece of rubber.

Believe what you will; I maintain that the air displacement due to piston movement simply moves back and forth in the tube - no net movement.

Seems like he discovered it wasn't a long-term solution, though. Alvincullumyork - is that still on there?

Exactly. 650cc in and 650cc out , back and forth continuously. Considerably more volume than the tube and oil separater.

+1 on chopping up a plastic cutting board to make a slider. I made this from a plastic sheet very similar to a cutting board. Used a band saw to carve it out. A heat gun to bend.

There is a slight problem with plastic though, it will last forever but is very noisy.

Unless there is some malfuction allowing other air into the crankcase. Each piston stroke is followed by an equal and opposite stroke, resulting in a "vibration" of air mass in the tube, not net migration.

What have you done to our buddy OFFandON?

Makes sense. But ancdotal evidence seems to disprove intuition: 1) if you feel near the end of the long tube in the airbox while the engine's running, it won't seem like that much air pumping, especially when revving to cruising rpms. And 2) when I put in new rings, it cut the oil condensation considerably. Perhaps there's some air compression due to inertia and flow restriction going on.

You should change your handle.
In fact let's have a Top Ten List for New Handles for OFFandON.
#9 William Buckley 650
