What is a Pod filter?

I guess that is it. What is a pod filter. I have a chrome v-8 breather with a piece of 1-1/4 heater hose to connect it to the carb. I havent put it on yet because with when I was trying things out I discovered that the engine just dies when you hit the gas w/o the stock air box. What size main jet should I start out with to try this.

these are unifilters:

and pod filters are gauge wire filters, like K&N's.

Guys that claim to have gotten it to work usually run #80 - #90 jets.

i hav found, when running a hi-flow filter, you lose some of the "snap" from bottom end.

Totally. It has to do with the design of the airbox. I've been so unimpressed by them I've quit messing with them for a time. If you can connect a piece of hose to the carb, lengthening the intake tract, it helps the scoot draw air better at lower RPM. The airbox volume helps the scoot draw air better at a variety of RPMs, rather than just being optimized for one.

for a stock engine don't even bother, i only use them on engines above 82cc and hope it doesn't rain!

Yeah, I think at that point you can actually use the airflow. Either way, you'd be running a larger carb that won't fit the stock airbox tube. I wonder, though, if you created a larger tube to the stock airbox and opened up those little airbox inlets by the same amount you bumped up the carb, if you wouldn't get a better running scoot that could run with a smaller main jet.

Some guys have posted positive results with stock displacements and pods, though, so I haven't completely written them off.

kuka makes tubes with the oversized lip opening to fit on a bigger carb.

At 72cc you could use a DDx airbox but they are hard to comeby. Most guys in the 808 use the pods,uni or nothing at all.

hahahah. why eould you say that???
:lol:

but yes, they used to carry it, i believe there are still some there. i used one to adapt my stock sym dio50 airbox to a 28 oko carb

i have found when running a pod filter on a spree. it good to have a velocity stack on... but its more effective when you have a velocity stack.
