jetting with pod filters
« on: May 22, 2014, 08:18:02 AM »
Im in my last few tasks before I can finally fire my sumo.
I built a 86 motor and switched from the mikuni to the keihin pwk 39
In the process of finding a place to put a battery I added a foam pod filter and removed the air boot leaving the box empty.
Whats a good place to start since Im using just a pod and switching carbs?

Cant say I blame you :-)
I thought since the bike is only going to seeing asphalt why not let it breathe.

I've got a 4" by 4" Uni filter Pod on my 87 K5 quad Goatzilla. At 700ish feet above sea level I'm running 55 pilot 165 main on a PWK. Don't remember if it's a 38mm or 39mm carb. About the only thing different between mine and anyone elses is I custom built my own pipe so my jetting may be too lean for someone with a unmolested pipe. I'm also running an outerwears filter on top of the uni inside a 5 sided airbox I built. It has an open top to pull in all the air it needs from under the seat without getting coated in the elements from the rear tires.

It's hard to keep a drivers license riding a 2 stroke dirt bike on the street.  If you drive within the law they are VERY boring.

I fitted up one of the fmf pipes for the af conversions with a Q silencer for the cr 500. I'm also running a v-force 2 with the uni pod as well.
I hadn't seen much about the older motors switching from mikuni's, and given the few slight mods I've made I wanted to see if anyone else is doing anything similar.
I'm like 4 feet above sea level :-D
