I had a chinese scooter before I bought my big boy bike, and I found it had numerous flaws in design from the factory. I needed to lose the stock airbox, and add a unifilter. When I did that, my oil breather hose, which was attached to the stock airbox needed to go somewhere. There was more than a tablespoon of oil gathered in the bottom of the stock box, so I didn't feel comfortable with routing the breather hose out the bottom of the bike to possibly add some 'slick' to the rear tire. It was squirrely enough to ride on 13's without adding any slidey slippery stuff on the tires!
My solution was to find something that would easily fit into the space and would be easy to empty if necessary. It also had to breathe, as that was the whole point to an OIL BREATHER. I didn't really have any ideas, other than it should be something easy to work with, so aluminum was at the top of the list. Actually free and already designed was at the top of the list, but no such luck. Something with some creative style was also in order. Space is extremely limited, as this fits under the seat, and over the cylinder head, and behind the carb. Tight fit!
Ladies and Gentlemen, I present to you my less than $50 dollar mod: Martini Shaker Oil Breather.
2- 4" hose clamps, local auto store.
1- 10" aluminum flat stock, laying around the garage. It attaches to stock bolt holes, then is riveted to hose clamps.
1- threaded brake hose fitting. I drilled out the ball, and bolted the fitting into the bottom of the shaker with a washer on each side for more strengh.
1- brushed aluminum martini shaker, $8.00 at Target. (department store here in the US for you out of towners.
)
The breather is easily removed from the clamps, and can be emptied into your dirty oil container and re-installed. I leave the top cap off, as the breather is supposed to be vented, and the martini strainer is just the thing for that. The liquid that gathers inside never got up high enough to splash out.
Enjoy.
Below is a pic of the scoot to give you some idea of what I was working with last winter.
