My take on a PVC intake...

I'm hoping the long tube down the center will solve the dirty air problem as well as restrict the air flow to a tunable lever. As this looks promising on the bench in my garage with a shop vac providing the vacuum source we all know the real world may be a different animal. Right now my bike is in the middle of major modifications and will not be runable for sometime and not to mention it's January in northern Indiana it may be sometime before I can test this theory on a runable bike. All constructive input is welcome.

 

forgive me for sounding stupid,i am english after all.but if you run a tube down the centre of the filter with a hole in the end as per the bottom pic,will it not just b drawing unfiltered air into the carb? or are you planning to plug the end so air is drawn thro the filter then pulled thro the tube to carb?

 

The first pic is it fully assembled the last pic is how it looks with the pod filter removed just so you can have some ideal of how it looks. The tube fits inside the filter with about a 1/2 inch gap from the bottom of the pod so all air will be drawn through the filter then down the tube.

 

thats pretty cool....

when u put them on the bike, you should let us know how they work

 

Thanks Schooter will keep everyone informed. Wish I had a runner right now to test on. This is actually Ricks ideal I'm just trying to make it reality it's nice to have his brain to bounce ideals off.

 

Hey Sour, great idea on the pipe, I read on another post that there may be melting from gas ? can you confirm this ?

 

i was just about to ask the same thing.sure i read on here somewhere that someone did something similar,but after a few months i think it was the plastic was getting mis-shaped as it got hot then they wdnt seal properly.i forget who it was now,but im sure he decided in the end to remake them in alloy or stainless?

 

I think you may be referring to me, but those where carb to head intakes. I don't think the same problem would happen since this is a air intake. There would be some exposure, but very little. Still, using large fuel line would be better.

 

Before you experiment with a Manifold.
Try addressing the issue needed to eliminate a major portion of the lean running problem.

Seal the Kidney-shaped Atmosphere Orifice.
Add a "Vent" beyond the Vortex Pods allow too form that lowers Air Pressure at the Atmosphere Opening.

With a supply of Atmosphere reaching the Cavity below the Diaphragm and feeding the Main AIR Jet ... the Carbs wont run so lean.

 

Rick has anyone tried this? i might give it a go this winter and take pics along the way, sacrifice marie in the name of science.... i like your idea, and have been looking for a project like this...

 

No. I don't know of anyone who has tried it yet.

This can be done without fear of restoring the Rack to "Normal"

Drill the Port to an I.D. that will allow you to fit a Grommet to Hold a Hose Fitting.
Buy four Rubber "Solid Grommet-type Plugs" to cap the Holes if you return to stock.

I'm confident that (2) -- 2-Into-1's will do the trick.
