hack off the 4 bolt mount, a little cleanup, silicone coupler and mount dual air filters 8-)

Yeah Kris, my thoughts exactly.

Still working out the details and need to order a USED one to play around with and see if it is even doable ...

Perhaps a few thousand hours with some sandpaper would thin it down to a manageable piece?

Linkert Intake Manifold

Quote:

Linkert Intake Manifold Harley Knucklehead 1936 to 1939 61"

Here is a new in the package replica manifold as used on 1936 to 1939 Harley Big Twin Knuckleheads, OHV EL 61". Also used on 1942 ELA & ELC army knuckleheads. This is a faithful reproduction of the so called "baby butt" manifold that used the 2" nuts with brass seals and mounted a 3-bolt brass Linkert carburetor. This one can only be used on the small port knuckles. It has the raised "503-35" for authenticity.

What about using a PVC Y-adapter? It would be much lighter and flexible.

I assume you're doing this for "show" and not for "go".

for "GO" ... no trailer queens for me ... ;)

Ya think the stock filter is that restrictive for a low RPM thumper?

another way to do it...

home made tea
heavy wall 2.25 ID rubber tube
cut a 2" thru both sides or slightly smaller.
push a 2" tube thru with some gorilla glue on the outside.
open a hole in the 2" tube to match the id of the rubber tube.

If you run a dual filter how do you jet for something like this? I have mine rejetted with a K&N filter in the airbox and the side door off with the outside panel covering the hole. What do you do with the black tube from the head to the airbox when you do a cone filter?

You jet it the same as any other bike.....trial and error. You install a pilot jet and see if the idle mixture screw is between 1.5 - 2.5 turns when the mixture is set properly. You go for a full throttle run and see what size main jet makes the bike run best.....then you start fiddling with the needle to get the mid-range proper. Dual air filters is not likely to change much of anything with the pilot jet.....as there is very little air flow through the filter.

CHANMAN,

jetting for dual filters isn't gonna be an issue, as Dave pointed out, it's a matter of getting the fuel/air ratio dialed in. Dave's instructions are what everyone uses when swapping out our stock box for open filters.

The dual filter setup is just for looks, as long as I keep the airflow as close to stock without restrictions, it should be fine.

The Lancer Jet Set in the MarketPlace has all the jets and parts we need to play around with while getting things dialed in. ;)

Now if I can remember who sells the stainless steel cap-head kit for our carbs, I'll be golden.

You can add 16 filters if you want. The bike can only inhale so much air. You rejet to mix the proper amount of fuel with whatever amount of air the engine is sucking in. Multiple filters shouldn't make much difference beyond what one free-flowing filter can do.

If you look really hard, you can see a motorcycle in the background! It only took me 4 minutes!

Okay cool. I have the jetset from lancer. I might do a dual filter one day. It is pretty cool idea.

the idea came when I was being stubborn and was refusing to relocate the battery, but remove the airbox and intake guts. A lot of the single filter folks just mash up the filter under the seat, or run a 90° elbow out the right side.

I figured if I was gonna MOD a 90° elbow out the side, why not run DUALS and have a nice symmetrical intake setup ...

Maybe I could run a longer tube over the battery and then 90 degree down behind battery with a filter on both sides
