Breather hose with pods?

Forces

As you say, the lateral forces will always be down through the frame (what for air craft is called a coordinated turn where you are pressed down into your seat and your drink doesn't slosh one way or the other), however it is possible with hard braking or acceleration to get spill overs longitudinally(ask me how I know about a coffee cup). Some members here might also like to perform a death defying procedure called a "wheelie". I might need some paper for that. The breather bottle could use some too.

Not exactly. On a bike any point other than the Center of gravity will get some side force when the bike's angle is changing, for instance a sudden change from a hard right turn to a hard left turn will put a force to the right on anything above the center of gravity, only during the time the angle is changing. Especially during the time the rate of change in angle is changing. Oil would theoretically slop out, but there should be no oil in the first place unless your engine is very worn indeed. Use asparagus oil and no one will know the difference.

Well not exactly not exactly

>>>>On a bike any point other than the Center of gravity will get some side force when the bike's angle is changing,

The bikes rotation is about the tire patch and so the frame roll induces a lateral (inertial) translation of the bikes CG (e.g. with respect to the tires patch line of travel). It is not a free inertia where rotation would occur about the C.G. The tire patch is an additional boundary condition.

We are now getting fully immersed in the second order dynamic effects.:shock:. I don't want to start taking about the flipping effect this has on the viscous medium in the bottle .

I'd say put it in a bottle and let it shake around, but use gravity (and centripetal acceleration) to keep it in (i.e put the filter vertical and the enclosed bottle down in the bikes z- frame). \\/

Ok, what about when the bike is sitting on the sidestand parked. My bike leans pretty far and I think it will spill out. The reason I have no room under my seat is that I rerouted my harness and have a plate that I bolted the starter relay, fusebox, rectifier too. Plus I stiil havea tool tray.

I found this on ebay and I think I will buy it and see if I can make it work.

Wow there are really a bunch of pretty ones over at flea bay

Ray mentioned having a return line to the engine.

There are at least two fitting on each of the ones I've seen. So if you run the breather hose to one, do you hook the other to the breather filter? How would you route the oil back to the engine? What would get it there?

Boy this is shore pretty ; too bad it gets to hold all that crappy breather oil......

TIA

Mine does not spill... ever. If it did, I would certainly change it.

On a street bike, you could route it to the exhaust and burn the vapor that way.

For the most part we use plastic juice and pop bottles. Stuff them about half full with paper towels. Add 10 or so small vent holes at the top. A couple of ties and call it good. Much lighter/cheaper than those fancy bottles. Clean them once a season at best. Unless things go bad, we don't get much in them.

The cases build pressure and need to vent, so if you route back to the cases, you still need some sort of vent.

Theres alot of those type of cans on there, but they all seem to big.

[andrewclaycomb]

Mine's run back to a plastic paint can lid strapped to the frame, with a K&N crankcase filter on it. I stoled the idea from Keith. :-D

Where did you get that braided hose and what size is it? Got a web link?

I bought my hose from www.summitracing.com They carry a bunch of different brands. I think mine was the Spectre brand. You can buy it in various lengths. I used it for the crankcase vent line, oil cooler lines, and fuel line.
It's 3/8".

Jeez. I never knew a simple breather catch could be so difficult.

[PAULYBOY]

Go to the grocery store and buy a kid size water bottle (12 ounces) in black. Remove the water nipple pull out thingy from the lid, leaving you a perfect place to put the hose in the top. Thick black wire ties to a black frame, and it becomes an object of stealth.

Call me over the top

Approximate Dimensions are:

2.7" diameter and 4.8" height
Made specifically for small engine space cars to reduce oil blow by and for compact engine vehicles.

Now where to get those braided lines......:?

P.S
Ray says if you want to put a return back to the engine that you should tap into the engine case above the clutch basket and run the return there.

:-D
Thanks Ray

Yes, the other is the vent line, not a return line. If your pulling from the top of the motor, doubt you will see much oil. My old worn out GS will maybe show a few table spoons after a season. Now if you remove the pads from the beather cover that keep the oil from splashing around, you will have issues. So you already have a return system built into the motor. The pads act as a filter, and gravity does the rest.

The only time I heve seen anyone return oil to the cases is with a turbo (has to return). The vapor that gets into the can is nothing I want in my motors anyway.

On the race bikes, we use an electric pump on the race bikes to pull a vacuum on the cases and still just vent to a pop bottle. I will say, those fancy bottles do look nice.
